Which one is removed from substrate during glycolysis

Options

A. Hydrogen
B. Electrons
C. Both A and B
D. Oxygen

Answer

**Step-by-Step Solution:**

1. **Understanding Glycolysis**: Glycolysis is a metabolic pathway that converts glucose into pyruvate, producing energy in the form of ATP. This process occurs in the cytoplasm of the cell and is the first step in both aerobic and anaerobic respiration.

2. **Breakdown of Glucose**: During glycolysis, one molecule of glucose (which is a 6-carbon compound) is broken down into two molecules of pyruvate (each being a 3-carbon compound).

3. **Removal of Atoms**: In the process of converting glucose to pyruvate, certain atoms are removed from the substrate (glucose). Specifically, hydrogen atoms and electrons are removed during this conversion.

4. **Identifying the Correct Option**: The question asks which component is removed from the substrate during glycolysis. The options provided are:
- A) Hydrogen
- B) Electron
- C) Both A and B
- D) Oxygen

Since both hydrogen and electrons are removed during glycolysis, the correct answer is option C, which states "both A and B".

5. **Conclusion**: Therefore, during glycolysis, both hydrogen and electrons are removed from the substrate, leading to the formation of pyruvate.

**Final Answer**: The correct answer is option C: both hydrogen and electron are removed from the substrate during glycolysis.
