Question

Which of the following is/are TRUE of an enzyme?

Enzymes lower the release of free energy

Enzymes are not consumed in a reaction

Not all enzymes are proteins

Enzymes only affect endergonic reactions

Enzymes only affect exergonic reactions

Expert Solution

Step 1

Enzymes are proteins that reduce the activation energy of processes. In most cases, each enzyme only binds to one substrate. Enzymes are not consumed during a reaction; instead, they might bind new substrates and catalyse the same reaction over and over again.

All enzymes are proteins.

It's vital to remember that whether a reaction is exergonic (spontaneous) or endergonic is unaffected by enzymes. This is due to the fact that they have no effect on the free energy of the reactants or products. They just lower the required activation energy for the reaction to proceed.
