The stage of cellular transportation at which the most ATP is produced is during the electron transport chain. This stage produces a total of 32 ATP molecules for every glucose, according to the Indiana University Purdue University Indianapolis Department of Biology.
Three of the four stages of cellular respiration produce ATP. The first stage, glycolysis, occurs in the cytoplasm of the cell. During this stage, one glucose molecule is broken into two pyruvic acid molecules. This results in the production of two ATP molecules for every glucose used.
The pyruvic acid is taken to the mitochondria during the transition reaction, which is the second stage of cellular respiration. The pyruvic acid is then converted to acetyl CoA. During the Krebs cycle, which occurs in the mitochondrial matrix, all the hydrogen atoms are taken from the acetyl CoA. Four ATP molecules are produced during the Krebs cycle.
The final step of cellular respiration is the electron transport chain. The NADH produced during the Krebs cycle carries the electrons from hydrogen down the electron transport chain.Learn More
Faculty resources from Thomas Nelson Community College explain that cellular respiration is the process by which cells produce adenosine triphosphate, or ATP. ATP is the molecule that carries energy for the cells of an organism, and it functions as a “currency” for the cells in an organism. Cells cannot store ATP; instead, they must produce it continuously or the organism will die.Full Answer >
Cellular respiration is directly related to breathing, as breathing provides the necessary oxygen molecules for the process of cellular respiration to take place; cellular respiration is a process by which cells acquire energy. The oxygen provided by breathing is used as a final hydrogen acceptor for the process, explains Antranik.org.Full Answer >
Cellular respiration occurs in the cytoplasm of prokaryotic cells and the mitochondria of eukaryotic cells. The process can be aerobic or anaerobic, and is used as a means of energy production for the cell.Full Answer >
Cellular respiration takes place in the mitochondria. This is where the chemical energy of glucose, carbohydrates, fats and proteins is harvested and partially captured in the form of ATP. Cellular respiration involves glycolysis, the Krebs cycle and oxidative phosphorylation via the electron transport chain. Glycolysis occurs in the cytosol, and the other two processes occur in the mitochondria. In the absence of oxygen, respiration is confined to the cytosol.Full Answer >
