Question

what is this pathway?
a kreb cycle
b electron transport chain
c fermentation

Explanation:

The Kreb cycle (also known as the citric acid cycle) involves the conversion of acetyl - CoA (formed from pyruvate) into citric acid (as seen in the diagram). It produces \(NADH\), \(FADH_2\), \(CO_2\), and a small amount of \(ATP\). The Electron Transport Chain is mainly about the transfer of electrons to generate a large amount of \(ATP\) through chemiosmosis (not depicted here). Fermentation occurs in the absence of oxygen and typically produces lactic acid or ethanol (no such products shown here).

Answer:

A. Kreb cycle
