What is the outcome of the Krebs cycle?

Answer 1

Products of one cycle:

2 CO2

3 NADH

1 GTP (or ATP in bacteria)

1 FADH2

Acetyl-CoA (6 carbon) enters the cycle, and is converted into 2, 3 carbon molecules.

Answer 2

Krebs cycle or citric acid is Complete oxidation of acetyl CoA without electron transport

The sum of all reactions in the citric acid cycle is:

Acetyl-CoA + 3 NAD+ + FAD + GDP + Pi + 3 H2O →

CoA-SH + 3 NADH + H+ + FADH2 + GTP + 2 CO2 + 3 H+

Two carbons are oxidized to CO2, and the energy from these reactions is stored in GTP , NADH and FADH2. NADH and FADH2 are coenzymes (molecules that enable or enhance enzymes) that store energy and are utilized in oxidative phosphorylation.

The end result of Krebs cycle is 2 ATP, 6 NADH, 2 FADH2, 4 CO2

Answer 3

The Krebs cycle produces energy in the form of ATP through the oxidation of acetyl-CoA. It also generates NADH and FADH2 molecules, which carry high-energy electrons to the electron transport chain for further ATP production. Additionally, the Krebs cycle produces carbon dioxide as a byproduct.
