In glycolysis, during oxidation electrons are removed by

Options

A. ATP
B. GAP
C. `NAD^+`
D. molecular oxygen

Answer

**Step-by-Step Solution:**

1. **Understanding Glycolysis**: Glycolysis is the metabolic pathway that converts glucose into pyruvate, releasing energy and producing ATP and NADH in the process. It consists of ten enzyme-catalyzed reactions.

2. **Identifying the Oxidation Step**: During glycolysis, one of the key steps involves the conversion of glyceraldehyde 3-phosphate (G3P) to 1,3-bisphosphoglycerate (1,3-BPG). This step is crucial as it involves the oxidation of G3P.

3. **Role of NAD+**: In this specific reaction, the oxidation of G3P involves the removal of electrons. The molecule that accepts these electrons is NAD+ (Nicotinamide adenine dinucleotide).

4. **Formation of NADH**: When NAD+ accepts the electrons during the oxidation of G3P, it is reduced to NADH. This means that NAD+ acts as an electron carrier, facilitating the transfer of electrons in the glycolytic pathway.

5. **Conclusion**: Therefore, in glycolysis, during the oxidation phase, the electrons are removed by NAD+.

**Final Answer**: NAD+ is the molecule that removes electrons during oxidation in glycolysis.
