Does an enzyme use a substrate, and cause a reaction to make a
different molecule, that is termed the product.
Such as in the substrate glucose, in the first step in glycolysis?

anonymous · Answer

Glycolysis comprises the 10 steps, which are catalysed by different enzymes.
In the first step glucose is converted to glucose-6-phosphate by the enzyme:glucokinase or hexokinase. this enzyme is utilizing ATP and mg2+ ions.

To answer the first part of your question: yes. There can be a single substrate complex or a multiple ones. During their reaction with the enzyme on the active site, the subtrates within the complex creates a new chemical composition through the enzymatic mechamism (forming the product), but the enzyme itself doesn't change.
