Question

An enzyme is a catalyst used by living things to promote and regulate chemical reactions. What is the most likely enzyme for the chemical reaction depicted below?

A. Catalyst A
B. Catalyst B
C. Catalyst C
D. Catalyst D

Answer 1

B. Catalyst B

Step-by-step explanation:

Explanation: Enzymes are complex proteins that have a very specific shape. Just as a key fits a lock and allows it to open, the active site of the enzyme fits the reactants, allowing them to meet at the right orientation to form new chemical bonds. The shape of catalyst B is the best fit to the given reactants and product. The presence of catalysts allows reactions to proceed at much lower energy levels than without, as high-energy collisions between molecules are no longer necessary.
