9. TRUE OR FALSE
1. The oxygen we inhale is the final electron acceptor in the electron transport chain and allows aerobic respiration to proceed, which is the most efficient pathway for harvesting energy in the form of ATP from food molecules.
2. Electron transport chain
Electron transport chainThis stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle). The electron transport chain takes place in the mitochondria. This stage converts the NADH into ATP.
3. The first stage of cellular respiration, called glycolysis, takes place in the cytoplasm. In this step, enzymes split a molecule of glucose into two molecules of pyruvate, which releases energy that is transferred to ATP. The organelle called a mitochondrion is the site of the other two stages of cellular respiration.
4. No Explanation
5. Mitochondria are double-membrane enclosed eukaryotic organelles with a central role in numerous cellular functions. ... The inner membrane is composed of two subcompartments, the cristae membrane and the inner boundary membrane.
6. During the process of glycolysis in cellular respiration, glucose is oxidized to carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).
7. Organisms carrying out fermentation, called fermenters, produce a maximum of two ATP molecules per glucose during glycolysis.
8. Aerobic fermentation is a metabolic process by which cells metabolize sugars via fermentation in the presence of oxygen and occurs through the repression of normal respiratory metabolism (also referred to as the crabtree effect in yeast).
9. No Explanation
10. During the process of glycolysis in cellular respiration, glucose is oxidized to carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).
