Ethics in production and operations management refers to the principles and values that guide decision-making and behavior in the production and management of goods and services. These principles and values help ensure that production and operations are conducted in a manner that is fair, responsible, and sustainable.
One key ethical consideration in production and operations management is the treatment of employees. This includes issues such as fair wages, safe working conditions, and opportunities for advancement. Companies that prioritize the well-being of their employees are more likely to have a positive impact on their communities and the environment.
Another important ethical consideration is the environmental impact of production and operations. This includes issues such as the use of natural resources, pollution, and waste management. Companies that prioritize sustainability and minimize their environmental footprint are more likely to have a positive impact on the planet and contribute to the long-term prosperity of society.
Another ethical issue in production and operations management is the treatment of suppliers and other stakeholders. This includes issues such as fair and transparent business practices, responsible sourcing, and the maintenance of good relationships with suppliers. Companies that prioritize the well-being of their suppliers and other stakeholders are more likely to have a positive impact on their communities and the environment.
In conclusion, ethics in production and operations management is a crucial aspect of responsible business practices. It involves the fair treatment of employees, the minimization of environmental impact, and the responsible treatment of suppliers and other stakeholders. Companies that prioritize ethics in their production and operations are more likely to have a positive impact on their communities and the environment, and contribute to the long-term prosperity of society.
2.23: Photosynthesis Summary
The combination of carbon dioxide with ribulose biphosphate gives an unstable 6-carbon compound which splits immediately into two molecules of a 3-carbon Compound, phosphoglyceric acid PGA. In C 3 plants in the presence of fructose-2,6-bisphosphate the K m FBP of the cytosolic fructose 1,6-bisphosphatase is rather low at 20 μM. This improved performance has enabled native C 4 species to dominate hot, open landscapes of low latitudes, and warm temperate regions receiving summer rain. Leaf anatomy in C4 plants differs see Fig. In order for photosynthesis to take place, it needs these three things: Water, carbon dioxide, and sunlight. In the next step, the energy from the light reaction transforms carbon dioxide into glucose. Again, this reflects high concentrations of glycerate-3-P in the bundle-sheath and the fact that a gradient of P i must exist between the mesophyll and bundle-sheath, following its release in sucrose synthesis Fig.

What is Photosynthesis
Without photosynthesis there would be little to no oxygen on the planet. A photon contains one quantum of light energy. For more information regarding the photosynthesis process step by step, go through the course materials available on our website! Joseph Priestley was another scientist who contributed to the discovery of photosynthesis Jan also discovered that plants have cellular respiration just like animals. Light is needed for this process and is absorbed by pigments. Dark reactions will not continue if plants are taken away from light for too long. The starch is not the only end-product of photosynthesis. It is the basic reaction on which the entire world depends.

On the other hand, in the case of bacteria, hydrogen sulphide replaces the water along with carbon dioxide to release carbohydrates, sulfur, and water molecules. The phosphate translocators of the bundle-sheath and mesophyll of Panicum milaceum, an NAD +-malic enzyme species, have also been shown to differ in their affinities for PEP, triose-P and glycerate-3-P. The phosphate translocator in chloroplasts of C 4 plants is distinguished from that found in chloroplasts of C 3 plants by its additional ability to transport PEP and glycerate-2-P. DNA is found in chloroplasts Stocking and Gifford, 1959. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. According to Brawerman 1966 this DNA differs from nuclear DNA in GC guanosine and cytosine content.

They are put into two different units; Photosystem I and Photosystem II. Plants carry out both photosynthesis and cellular respiration. The photochemical reaction takes place in the thylakoid membranes. How do plants absorb sunlight for photosynthesis? Light-dependent reactions When a photon of light hits the reaction center, a pigment molecule such as chlorophyll releases an electron. Energy moves from molecule to molecule to get to a chlorophyll molecule called P700, which absorbs red wavelengths at a range of 700 nanometers.

Photosynthesis
They do this by a process called photosynthesis. Because of this, such plants are called C 4 plants in contrast to those that produce 3-carbon PGA which are known as C 3 plants. Humans and other animals consume these stored materials and finish the loop of the food chain. It takes plate in the plant stroma, the inner space in chloroplasts. During respiration, plants take up nutrients just to keep the plant cells from dying. Without it, plants would not have access to the energy in the sugar glucose. Also on the basis of differences in quantum yield, C 4 dicots are predicted to not have gained an advantage over C 3 monocots and dicots until CO 2 concentrations fell below about 250 μmol mol -1, which occurred during glacial maxima in the Quaternary.

Photosynthesis: Essay on Photosynthesis (2098 Words)
Pigments absorb the light that is used in the photosynthesis process. From a photosynthetic standpoint, the greatest advantage of C 4 photosynthesis is in situations that promote photorespiration in C 3 plants, most notably high temperature and low intercellular CO 2 concentrations that result from restricted stomatal aperture and low atmospheric CO 2. About 1500 species are a variety of dicot species, some of which form woody tissues and grow as shrubs and small trees. Because natural C 4-dominated grasslands and savannas often occur on more productive landscapes, they too have been heavily exploited for agricultural purposes, resulting in habitat loss and impoverishment of the native C 4 flora of the planet. The biologist suggested that there were differences in the light-dependent stage and was used as a source for hydrogen atoms, Niel suggested that hydrogen should be transferred from hydrogen sulfide or into the water. It releases oxygen as a byproduct. Adapted from Larcher W 2003 Physiological Plant Ecology.

This is then transported into the BS mitochondria for decarboxylation. Image Courtesy : co2crc. Elevated CO 2 will enhance photosynthetic efficiency and yield of C 3 rice plants, perhaps more than might be obtained with C 4 rice. When the sugar is made, it gets broken down by the mitochondria used to produce energy in a cell to produce energy for the growth of the plant. Living creatures breathe in oxygen and release carbon dioxide as a byproduct. Almost half a century passed before the Overall reaction of photosynthesis In chemical terms, photosynthesis is a light-energized 2O , producing oxygen gas O 2 , + , and 2 , which is reduced to organic products.

Photosynthesis is the process using which green plants and some other organisms convert light energy into chemical energy. This process uses a four-carbon compound intermediate called oxaloacetate which is opens in new tab , according to Biology Online. The third step is the sunlight releases energy to the chloroplasts to create glucose which is sugar, the food. If it we didn't have photosynthesis could we live? Heats speeds up the rate of photosynthesis. Examples include Indian pipe Monotropa uniflora — also known as the ghost or corpse plant — and beechdrops Epifagus americana , which steals nutrients found in beech tree roots. Furthermore, the location of the primary decarboxylation enzyme differs between the 3 C4 types. All the significant reactions of the photosynthesis process generally take place during the daytime in the chloroplasts of leaves.

Conclusion Of Photosynthesis
C4 plants also have a high water-use efficiency WUE compared to C3 plants, and this contributes to their success in arid or highly saline environments Table 1. In both C 3 and C 4 plants, reduction of oxaloacetate and export of the malate produced results in the export of reducing equivalents from the chloroplast. Unlike C3 plants, the mesophyll cells have no rubisco activity Way, 2012 , and instead use the enzyme phosphoenolpyruvate PEP carboxylase PEPc , which has no affinity for O 2 to carry out the initial fixation of CO 2 from the atmosphere. In C 3 plants, the low atmospheric CO 2 levels of recent geological time promoted substantial inhibition of photosynthesis by photorespiration in hot conditions, particularly if water was also limiting. Note the higher quantum yield for C 3 leaves at cooler temperatures, but the higher quantum yield for C 4 leaves at warmer temperatures. These differences in enzyme localisation may account for the slight differences in the C4 cycle between plant types.

C4 Photosynthesis
With the help of water and sunlight, they absorb carbon dioxide from the atmosphere and turn it into oxygen and carbohydrates. Cellular respiration breaks down complex organic molecules, releasing the energy they contain. What exactly is photosynthesis and why is it so important? So it is very important to protect all the natural elements involved in this process of photosynthesis. In conclusion, the process of photosynthesis is a major fuel of all life in some way. This NADH is then oxidized in the mitochondria to generate ATP for the PCK reaction Leegood and Walker, Chapter 4. As humans, in order to live plants, must take in gases.
