What is true about the end products of glycolysis?

Options

A. 2 pyruvic acid `+2ATP + 2NADH_(2)`
B. 2 pyruvic acid `+2NADH_(2)`
C. 1 pyruvic acud `+2ATP + 2NADH_(2)`
D. 2 pyruvic acid `+1ATP +1NADH_(2)`

Explanation

### Step-by-Step Solution:

1. **Understanding Glycolysis**: Glycolysis is the first step in the process of cellular respiration, where glucose is broken down to extract energy.

2. **Starting Material**: The process begins with one molecule of glucose (C6H12O6).

3. **End Products**: During glycolysis, glucose is converted into two molecules of pyruvate (C3H4O3).

4. **Energy Yield**: In the process of glycolysis, energy is captured in the form of ATP and NADH:
- **ATP Production**: Two molecules of ATP are produced directly during glycolysis.
- **NADH Production**: Two molecules of NADH are also produced. Each NADH can generate additional ATP during the electron transport chain.

5. **Total ATP Calculation**:
- Each NADH can yield approximately three ATP molecules when it is oxidized in the electron transport chain. Therefore, two NADH can yield about six ATP.
- Adding the two ATP produced directly from glycolysis, the total ATP yield from one glucose molecule through glycolysis is 8 ATP (2 ATP from glycolysis + 6 ATP from NADH).

6. **Final Summary of End Products**: The end products of glycolysis are:
- 2 molecules of pyruvate
- 2 molecules of ATP
- 2 molecules of NADH

### Conclusion:
The true statements about the end products of glycolysis are:
- 2 pyruvate molecules are formed.
- 2 ATP molecules are produced.
- 2 NADH molecules are generated.
