Question: Which step of glycolysis involves substrate-level phosphorylation?

Options:

Correct Answer: Conversion of phosphoenolpyruvate to pyruvate

Solution:

The conversion of phosphoenolpyruvate to pyruvate involves substrate-level phosphorylation, producing ATP.

Which step of glycolysis involves substrate-level phosphorylation?

Which step of glycolysis involves substrate-level phosphorylation?

Step 1: Glycolysis is a process that breaks down glucose to produce energy.
Step 2: During glycolysis, there are several steps where energy is produced.
Step 3: Substrate-level phosphorylation is a way to produce ATP directly in a metabolic pathway.
Step 4: In glycolysis, the specific step that involves substrate-level phosphorylation is when phosphoenolpyruvate (PEP) is converted to pyruvate.
Step 5: This conversion releases energy and produces ATP.
