How many atp per glucose. How many ATP are produced in the electron transport chain per one glucose? 2022-10-10

Glucose is a simple sugar that is an important source of energy for cells in the body. It is broken down through a process called cellular respiration, which occurs in the mitochondria of cells. During cellular respiration, glucose is converted into ATP (adenosine triphosphate), the primary source of energy for cells.

The breakdown of glucose into ATP occurs through a series of chemical reactions known as the citric acid cycle (also called the Krebs cycle) and the electron transport chain. The citric acid cycle takes place in the mitochondria and involves the conversion of glucose into intermediate molecules, such as acetyl-CoA, which are then used to produce ATP. The electron transport chain, which also occurs in the mitochondria, involves the transfer of electrons from intermediate molecules to oxygen, which generates a proton gradient that is used to produce ATP.

In total, the breakdown of one molecule of glucose can yield a maximum of 36 ATP molecules. This process is known as aerobic respiration, as it requires oxygen. If oxygen is not available, an alternative process called anaerobic respiration can occur, which produces a smaller amount of ATP. During anaerobic respiration, glucose is converted into ATP through a process called fermentation, which yields only 2 ATP molecules per molecule of glucose.

It is important to note that the actual number of ATP molecules produced from the breakdown of glucose can vary depending on the specific conditions of the cell and the efficiency of the cellular respiration process. However, in general, the breakdown of glucose into ATP is a crucial process that provides cells with the energy they need to carry out their functions.
