Answer:

O D. To provide molecules for the electron transport chain

Explanation:

The Krebs cycle, also known as the citric acid cycle, refers to a series of reactions during cellular respiration that produces energy by the oxidation of acetyl-CoA. The Krebs cycle utilizes acetyl-CoA and water in order to reduce the cofactor Nicotinamide adenine dinucleotide (NAD) to NADH, in a process that releases carbon dioxide (CO2). This NADH is then used by the oxidative phosphorylation electron transport pathway in order to generate ATP, the energy coin of the cell.
