Question

in the Krebs cycle the carbon atoms in a three carbon molecule are released in A one molecule of water B three molecules of oxygen C three molecules of carbon dioxide D one molecules of glucose​

Answer 1

In the Krebs cycle the carbon atoms in a three carbon molecule are released in Three molecules of carbon dioxide.

Answer: Option C

Explanation:

Kreb’s cycle is also known as the Citric acid cycle which during oxidation produces 2 Adinosine Triphosphates. In the Kreb’s cycle water is taken along with NAD+ and it is reduced to produce NADH sending out carbon in the form of the carbon dioxide. Three molecules of carbon dioxide is released.

In oxidation of glucose through glycolysis without the use of Oxygen 2 molecules of ATP is produced. This serves as the main source of energy.
