#Applied Microbiology

Consider the following statements regarding ATP production during aerobic respiration:

1. Substrate-level phosphorylation occurs in both the cytoplasm and the mitochondrial matrix.

2. The oxidation of one molecule of Acetyl-CoA in the Citric Acid Cycle results in 11 ATPs via oxidative phosphorylation.

3. The enzyme ATP Synthase (Complex V) utilizes the proton motive force to generate ATP in the intermembrane space.

Assertion (A) : The net gain of ATP during glycolysis is only 2 ATP, even though 4 ATP molecules are actually produced.

Reason (R): Two molecules of ATP are consumed during the preparatory phase of glycolysis to phosphorylate glucose and fructose-6-phosphate.
