Hydrolysis is a ……….... reaction and in glycolysis at ……..... Steps the ATP is hydrolyzed .

Options

A. Cleavage and two steps
B. Electron transfer and three steps
C. Condensation and two step
D. Rearrangement and three steps

Answer

To solve the question, we need to fill in the blanks regarding hydrolysis and glycolysis.

### Step-by-Step Solution:

1. **Understanding Hydrolysis**:
- Hydrolysis is a chemical reaction that involves the breakdown of a compound due to its reaction with water. It is often referred to as a cleavage process because it involves breaking bonds in the presence of water.

2. **Identifying the Type of Reaction**:
- Since hydrolysis involves breaking down a molecule (in this case, ATP) into smaller components (ADP and inorganic phosphate), we can conclude that hydrolysis is a **cleavage** reaction.

3. **Analyzing Glycolysis**:
- Glycolysis is a metabolic pathway that converts glucose into pyruvate, producing ATP and NADH in the process. During glycolysis, ATP is used in specific steps.

4. **Finding the Steps in Glycolysis where ATP is Hydrolyzed**:
- In glycolysis, ATP is hydrolyzed in two specific steps:
- The first step is when glucose is converted to glucose-6-phosphate, where one ATP molecule is hydrolyzed to ADP.
- The second step occurs when fructose-6-phosphate is converted to fructose-1,6-bisphosphate, where another ATP molecule is hydrolyzed to ADP.

5. **Conclusion**:
- Therefore, hydrolysis is a **cleavage** reaction, and in glycolysis, ATP is hydrolyzed at **two** steps.

### Final Answer:
Hydrolysis is a **cleavage** reaction and in glycolysis at **two** steps the ATP is hydrolyzed.
