Question

In glycolysis, electrons are removed by ______.

Options

• ATP

• NAD⁺

• glyceraldehyde- 3 -phosphate

• molecular oxygen

Answer 1

In glycolysis, electrons are removed by NAD⁺.

Explanation:

NAD⁺ is an electron acceptor in glycolysis. Electrons are eliminated and accepted by NAD⁺ during oxidation. Two NAD⁺ molecules are converted to two NADH molecules for every molecule of glucose. In the electron transport chain, the terminal electron acceptor is molecule oxygen. During glycolysis, glyceraldehyde- 3 -phosphate is decreased. ATP is the cell's energy currency.
