Question

Compare the three metabolic pathways the body uses to generate ATP, including site of production, ATP yield, duration, oxygen or substrate requirement, and corresponding optimal form(s) of exercise.

Answer 1

The body uses three pathways to generate ATP: glycolysis, pyruvate oxidation, and the citric acid cycle. Glycolysis is used during anaerobic exercise, while pyruvate oxidation and the citric acid cycle are used during aerobic exercise.

Step-by-step explanation:

There are three metabolic pathways the body uses to generate ATP: glycolysis, pyruvate oxidation, and the citric acid cycle.

Glycolysis occurs in the cytoplasm and generates a small amount of ATP by substrate-level phosphorylation. It does not require oxygen and can be used during anaerobic exercise.

Pyruvate oxidation occurs in the mitochondria and generates some ATP through substrate-level phosphorylation. It requires oxygen and is used during moderate exercise.

The citric acid cycle also occurs in the mitochondria and generates a small amount of ATP through substrate-level phosphorylation. It requires oxygen and is used during long-duration exercise.

Answer 2

Glycolysis, Krebs cycle and oxidative phosphorylation

Step-by-step explanation:

1.glycolysis yield net two ATP,Krebs cycle yield 2ATP but oxidative phosphorylation yield 34ATP

2.glycolsis occur in cytosol,Krebs cycle in mitochondria matrix while oxidative phosphorylation occur in mitochondria membrane

3.glycolsis substrate is glucose,Krebs cycle substrate is acetyl CoA which comes from pyruvate while substrate for oxidative phosphorylation reduced NAD and FAD which are generated from Krebs cycle and glycolysis
