Which one of the following is wrong about glycolysis

Options

A. It uses ATP
B. It produces ATP
C. End products are `CO_(2)" and H_(2)`
D. NADH `(H^(+))` is produced

Answer

To determine which statement about glycolysis is incorrect, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understanding Glycolysis**: Glycolysis is the metabolic pathway that converts glucose into pyruvate, generating small amounts of energy in the form of ATP and NADH. This process occurs in the cytoplasm and does not require oxygen (anaerobic).

2. **Analyzing the Options**:
- **Option 1**: "It uses ATP, it produces ATP."
- In glycolysis, 2 ATP molecules are consumed in the initial steps, and 4 ATP molecules are produced later in the process. Therefore, this statement is correct.

- **Option 2**: "End products are CO2 and H2, NADH, H plus is produced."
- The end products of glycolysis are two molecules of pyruvic acid, not CO2 and H2. While NADH and H+ are produced, CO2 is not a product of glycolysis. Thus, this statement is incorrect.

- **Option 3**: "NADH + H+ is produced."
- During glycolysis, NADH is indeed produced when NAD+ accepts electrons. This is correct.

3. **Conclusion**: The incorrect statement about glycolysis is that the end products are CO2 and H2. The correct end products are pyruvic acid, along with NADH and H+.

### Final Answer:
The wrong statement about glycolysis is: **"End products are CO2 and H2."**
