Question

what is the term used to describe the energy needed to get an enzyme reaction started?
o adhesion energy
o activation energy
o cohesion energy

Explanation:

Enzymes are biological catalysts. For a reaction to occur in the presence of an enzyme, a certain amount of energy is required to reach the transition state (the state where the reaction can proceed). Activation energy is defined as the minimum energy needed to start a chemical reaction. Cohesion energy refers to the energy that holds similar molecules together (like water - water molecules due to hydrogen bonding). Adhesion energy is the energy that holds different molecules together (e.g., water - glass molecules).

Answer:

activation energy
