Question

How many ATP molecules are produced by oxjdation of one molecule of acetyl-Co-A?

Options

• 6 ATP

• 12 ATP

• 32 ATP

• 24 ATP

Answer 1

12 ATP

Explanation:

When one molecule of acetyl CoA is oxidised,

1. it produces three molecules of NADH₂. The number of ATPs produced by three NADH₂ molecules is nine.
2. One FADH₂ molecule is produced. FADH₂-2 produces a total of two ATPs.
3. The number of ATP molecules generated is equal to one. 9 + 2 + l = 12 total ATPs created.
