`"Glucose + ATP" rarr "Glucose6 - phosphate + ADP"` The enzyme which catalyses the above reaction belongs to this class

Options

A. 1
B. 3
C. 4
D. 2

Answer

To determine the class of the enzyme that catalyzes the reaction:

**Glucose + ATP → Glucose 6-phosphate + ADP**,

we can follow these steps:

### Step 1: Identify the Reaction
The reaction involves the conversion of glucose and ATP into glucose 6-phosphate and ADP. This indicates that a phosphate group is being transferred from ATP to glucose.

**Hint:** Look for the components involved in the reaction to understand what is happening.

### Step 2: Understand the Role of ATP
In this reaction, ATP (adenosine triphosphate) donates a phosphate group. When ATP donates a phosphate, it is converted into ADP (adenosine diphosphate) and an inorganic phosphate (Pi).

**Hint:** Remember that ATP is a high-energy molecule that can transfer phosphate groups.

### Step 3: Identify the Enzyme Class
The enzyme that facilitates the transfer of a phosphate group to a substrate (in this case, glucose) is known as a kinase. Kinases are enzymes that catalyze the transfer of phosphate groups from ATP to specific substrates.

**Hint:** Think about the specific type of enzyme that transfers phosphate groups.

### Step 4: Classify the Enzyme
Kinases belong to a broader class of enzymes known as transferases. Transferases are enzymes that transfer functional groups from one molecule to another.

**Hint:** Consider the broader category of enzymes that includes kinases.

### Conclusion
The enzyme that catalyzes the reaction of glucose and ATP to form glucose 6-phosphate and ADP is a kinase, which is classified under transferases. Therefore, the correct answer to the question is that the enzyme belongs to the class of transferases.

**Final Answer:** The enzyme belongs to the class of transferases.
