The correct answer is B. Production of ATP from the breakdown of glucose.
Aerobic respiration is a metabolic pathway that uses oxygen to produce energy in the form of ATP. It is the most efficient way to produce ATP, and it is the primary pathway used by most cells.
Aerobic respiration begins with the glycolysis of glucose, which produces two pyruvate molecules. Pyruvate is then transported into the mitochondria, where it is converted into acetyl-CoA. Acetyl-CoA is then used in the Krebs cycle, which produces NADH and FADH2. NADH and FADH2 are then used in the electron transport chain, which produces ATP.
The overall reaction for aerobic respiration is:
C6H12O6 + 6O2 â 6CO2 + 6H2O + 38 ATP
Aerobic respiration produces 38 ATP per glucose molecule, which is much more than the two ATP produced by glycolysis. This is why aerobic respiration is the most efficient way to produce ATP.
Lactic acid is produced as an end product of anaerobic respiration, which occurs when there is not enough oxygen available. Anaerobic respiration is less efficient than aerobic respiration, and it produces less ATP.
Radiant energy is converted into chemical energy during photosynthesis. Photosynthesis is the process by which plants use sunlight to produce glucose. Glucose is then used by plants for energy or to store energy.
Polysaccharides are long chains of sugar molecules. They are used by cells to store energy.
