Pick out the incorrect statement about glycolysis

Options

A. It is anaerobic respiration
B. During glycolysis glucose is converted into pyruvate or lactate with generation of 38 molecules of ATP per molecule of glucose
C. Glycolysis provides energy to those cells which live without oxygen
D. It occurs in the cytoplasm of the cell

Answer

To solve the question, we need to analyze the statements provided about glycolysis and identify which one is incorrect. Here’s a step-by-step breakdown:

### Step 1: Understand Glycolysis
Glycolysis is a metabolic pathway that converts glucose into pyruvate or lactate, depending on the presence of oxygen. It is a crucial process for energy production in cells.

### Step 2: Identify Key Features of Glycolysis
- **Anaerobic Process**: Glycolysis occurs in the absence of oxygen.
- **ATP Production**: Glycolysis produces a net gain of 2 ATP molecules per glucose molecule.
- **Location**: Glycolysis takes place in the cytoplasm of the cell.
- **End Products**: The end products of glycolysis are pyruvate (or lactate in anaerobic conditions).

### Step 3: Evaluate Each Statement
1. **Statement 1**: "It is an anaerobic respiration."
- This is **true** because glycolysis can occur without oxygen.

2. **Statement 2**: "During glycolysis glucose is converted into pyruvate or lactate. With generation of 38 molecules of ATP per molecule of glucose."
- This is **incorrect** because glycolysis produces only 2 ATP molecules per glucose molecule, not 38. The 38 ATP figure refers to the total yield from complete oxidation of glucose in aerobic respiration (including glycolysis, Krebs cycle, and oxidative phosphorylation).

3. **Statement 3**: "Glycolysis provides energy to cells."
- This is **true** as glycolysis is a primary pathway for energy production in anaerobic conditions.

4. **Statement 4**: "It occurs in the cytoplasm of the cell."
- This is **true** since glycolysis takes place in the cytoplasm.

### Conclusion
The incorrect statement about glycolysis is the second one, which claims that glycolysis generates 38 ATP molecules per glucose molecule.

### Final Answer
The incorrect statement is: "With generation of 38 molecules of ATP per molecule of glucose."
