5 important questions on Tutorials - Enzymes

What is the temporary intermediate complex between an enzyme and its substrate called?

Enzyme-substrate complex

What is the enzyme’s impact on the energy required for a chemical reaction and the subsequent rate of the reaction?

Less energy input is needed to begin the chemical reaction and means the rate of the chemical reaction increases

What happens to the substrate or reactant in the course of an enzyme catalysed chemical reaction?

The substrate or reactant binds to the active site of the enzyme creating the enzyme substrate complex

What happens to the product in the course of an enzyme catalysed chemical reaction?

The product releases from the enzyme allowing the enzyme to be reused in another chemical reaction

Why is it that each different chemical reaction requires a different enzyme?

Substrate must have a specific shape to fit into the specific shape of the active site in the enzyme, which means a different enzyme is required to catalyse each different chemical reaction
