Which of the following is released during cellular respiration Rating: 8,3/10 1761 reviews

Cellular respiration is the process by which cells produce energy in the form of ATP (adenosine triphosphate). This process occurs in the mitochondria of cells and involves the breakdown of glucose, a simple sugar, into energy. There are three stages of cellular respiration: glycolysis, the citric acid cycle, and oxidative phosphorylation. Each of these stages releases different byproducts.

The first stage of cellular respiration is glycolysis, which occurs in the cytosol of the cell. In glycolysis, glucose is broken down into two molecules of pyruvate, releasing a small amount of ATP and NADH (nicotinamide adenine dinucleotide) in the process. NADH is a coenzyme that carries electrons and is used in the production of ATP during oxidative phosphorylation.

The second stage of cellular respiration is the citric acid cycle, also known as the Krebs cycle. This stage occurs in the mitochondria and involves the breakdown of pyruvate into acetyl-CoA, which is then used to produce ATP and NADH. The citric acid cycle also releases CO2 (carbon dioxide) as a byproduct.

The final stage of cellular respiration is oxidative phosphorylation, which occurs in the mitochondria and involves the use of ATP synthase to produce ATP from ADP (adenosine diphosphate) using the energy from NADH and FADH2 (flavin adenine dinucleotide).

In summary, the main byproducts released during cellular respiration are ATP, NADH, and CO2. ATP is the main source of energy for cells and is used to fuel various cellular processes. NADH and FADH2 are used to produce ATP during oxidative phosphorylation. CO2 is a waste product that is released during the citric acid cycle.

What substance is released during cellular respiration?

which of the following is released during cellular respiration

C NAD+ has more chemical energy than NADH. The filter was too large, and he needs a smaller mesh filter. It increases the surface for oxidative phosphorylation. The electrons gain free energy. C The rate of ATP production would decrease, but the rate of carbon dioxide production would increase.

You have a friend who lost 7 kg about 15 pounds of fat on a regimen of strict diet and exercise. D It yields energy in the form of ATP as it is passed down the electron transport chain. It allows for an increased rate of glycolysis. A 3 ATP, 6 CO2, 9 NADH, and 3 FADH2 B 1 ATP, 2 CO2, 3 NADH, and 1 FADH2 C 6 ATP, 6 CO2, 3 NADH, and 12 FADH2 D 3 ATP, 3 CO2, 3 NADH, and 3 FADH2 Exposing inner mitochondrial membranes to ultrasonic vibrations will disrupt the membranes. What is likely to happen when an athlete exhausts his or her ATP supply? C During aerobic respiration, muscles cells produce too much lactate which causes a rise in the pH of the muscle cells, thus athletes must consume increased amounts of sports drinks, high in electrolytes, to buffer the pH. There is more NADH than FADH2 made for every glucose that enters cellular respiration. A ATP is transported into the cell from the circulatory system.

which of the following is released during cellular respiration

The two processes of the carbon cycle are photosynthesis and cellular respiration. A two molecules of ATP are used and two molecules of ATP are produced. C Both oxaloacetate and citric acid will decrease. B He or she has to sit down and rest. D Other cells take over, and the muscle cells that have used up their ATP cease to function. Following glycolysis and the citric acid cycle, but before the electron transport chain and oxidative phosphorylation, the carbon skeleton of glucose has been broken down to CO2 with some net gain of ATP.

Carbon dioxide is released during which stages of cellular respiration?

which of the following is released during cellular respiration

ATP is a molecule that provides a small amount of energy to the cell, which provides it fuel to do specific tasks. A During anaerobic respiration, lactate levels increase when muscles cells need more energy; however, muscles cells eventually fatigue, thus athletes should modify their activities to increase aerobic respiration. Glucose is consumed, and carbon dioxide is produced. The citric acid cycle produces most of the ATP that is subsequently used by the electron transport chain. The function of the bonding of acetic acid to the carrier molecule CoA to form acetyl CoA is the reduction of glucose to acetyl CoA. A ATP will be produced from ADP and P i in the interior of the vesicle.
