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 breaking down of a compound by the addition of water. It is a type of cleavage reaction, as it breaks bonds in the presence of water.

2. **Identifying the Type of Reaction**:
- In the context of the question, hydrolysis can be classified as a **cleavage reaction**. This is because it involves breaking chemical bonds (specifically, the bonds in ATP) to release energy.

3. **ATP Hydrolysis in Glycolysis**:
- In glycolysis, ATP is hydrolyzed at specific steps to provide energy for the conversion of glucose into its phosphorylated forms.
- There are **two steps** in glycolysis where ATP is hydrolyzed:
- The first step involves the conversion of glucose to glucose-6-phosphate, where one ATP molecule is hydrolyzed.
- The second step involves the conversion of fructose-6-phosphate to fructose-1,6-bisphosphate, where another ATP molecule is hydrolyzed.

4. **Final Answer**:
- Therefore, the completed statement is: "Hydrolysis is a **cleavage** reaction and in glycolysis at **two** steps the ATP is hydrolyzed."
