Q1: Substrate-level phosphorylation occurs in?
Solution
Substrate-level phosphorylation occurs in both glycolysis and the citric acid cycle.
Step 1: Glycolysis This is the process where one glucose molecule is broken down into two molecules of pyruvate. During this process, substrate-level phosphorylation occurs twice. This results in the direct synthesis of two ATP molecules.
Step 2: Citric Acid Cycle (also known as Krebs Cycle) This is a series of chemical reactions used by all aerobic organisms to release stored energy. During this cycle, substrate-level phosphorylation occurs once per cycle, resulting in the direct synthesis of one ATP (or GTP) molecule.
So, in summary, substrate-level phosphorylation occurs in both glycolysis and the citric acid cycle.
