Consider the following
1. Two lactate molecules
2. Two Pyruvate molecules
3. Two ATP molecules
4. Two `NADH + 2H^+ `
Which of the above are the end products of aerobic glycolysis?

Options

A. 1 and 4
B. 1 and 3
C. 1, 3 and 4
D. 2, 3 and 4

Answer

To determine the end products of aerobic glycolysis from the given options, let's analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding Glycolysis**: Glycolysis is a metabolic pathway that converts glucose into pyruvate, generating energy in the form of ATP and NADH. It occurs in two phases: the preparatory phase and the payoff phase.

2. **Products of Glycolysis**:
- **Pyruvate**: During glycolysis, one molecule of glucose is converted into two molecules of pyruvate. This is a key product of both aerobic and anaerobic glycolysis.
- **ATP**: In glycolysis, two ATP molecules are consumed in the preparatory phase, and four ATP molecules are produced in the payoff phase. Therefore, the net gain of ATP is 2 ATP molecules.
- **NADH**: Two NADH molecules are produced during glycolysis as glucose is oxidized.

3. **Analyzing the Options**:
- **Option 1: Two lactate molecules**: This is incorrect for aerobic glycolysis. Lactate is produced during anaerobic glycolysis, not aerobic glycolysis.
- **Option 2: Two pyruvate molecules**: This is correct. Pyruvate is the end product of aerobic glycolysis.
- **Option 3: Two ATP molecules**: This is also correct. The net gain of ATP from glycolysis is 2 ATP molecules.
- **Option 4: Two NADH + 2H+**: This is correct as well. Two NADH molecules are produced during glycolysis.

4. **Final Conclusion**: The end products of aerobic glycolysis are:
- Two pyruvate molecules
- Two ATP molecules
- Two NADH + 2H+

### Answer:
The correct end products of aerobic glycolysis are:
- **Two pyruvate molecules**
- **Two ATP molecules**
- **Two NADH + 2H+**

Thus, the correct options are 2, 3, and 4.
