Question

Substrate level phosphorylation is:

• A. $\text{NADH synthesis}$
• B. $\text{Direct ATP synthesis}$
• C. NADPH${}_2\text{synthesis}$
• D. FADH${}_2\text{synthesis}$

Answer 1

The correct option is B $\text{Direct ATP synthesis}$

Substrate level phosphorylation is direct ATP/GTP synthesis.
NADH${}_2$ and FADH${}_2$ are converted to ATP via ETS.
NADPH${}_2$ is reducing power produced during photosynthesis.
