Tell the EC code number of hexokinase.

Explanation

To find the EC code number of hexokinase, we can follow these steps:

### Step 1: Understand what hexokinase is
Hexokinase is an enzyme that catalyzes the phosphorylation of hexoses, which are six-carbon sugars. This process involves adding a phosphate group to the sugar molecule, which is crucial for various metabolic pathways, including glycolysis.

**Hint:** Remember that hexokinase is involved in the phosphorylation of sugars, particularly glucose.

### Step 2: Know the role of hexokinase in glycolysis
