Question

the following graphic shows the energy curves for the same chemical reaction of a + b → ab.
enzymes are used in the chemical reactions that occur in living things. use the graphic to explain why these biochemical enzymes are important to these reactions.
enzymes raise the activation energy for the chemical reaction.
enzymes release energy that allows chemical reactions to occur.
enzymes absorb energy in a reaction to allow it to occur faster.
enzymes lower the activation energy needed for chemical reactions.

Explanation:

Enzymes act as catalysts. In the graph, the lower curve (which likely represents the reaction with an enzyme) has a lower peak (activation energy) compared to the higher curve (reaction without enzyme). Lowering activation energy means reactions occur faster, which is crucial for the efficient biochemical processes in living things.

Answer:

D. Enzymes lower the activation energy needed for chemical reactions.
