Question

Which of the following describes the role that enzymes play in the process of metabolism?

A: Enzymes carry the genetic instructions required for a cell to initiate metabolism.
B: Enzymes provide the chemical energy that is broken down and released during metabolism.
C: Enzymes store the chemical energy that is used to construct nucleic acid during metabolism.
D: Enzymes increased the rate of the chemical reactions carried out during metabolism.

Answer 1

D. Enzymes increase the rate of the chemical reactions carried out during metabolism. 

Answer 2

Answer: D: Enzymes increased the rate of the chemical reactions carried out during metabolism.

Step-by-step explanation:

Energy production in the cell requires the participation of many enzymes in a process called energy metabolism. Many of these reactions occur very slowly in the absence of a catalyst (a substance that accelerates the speed of chemical reactions). To solve this problem, cells have developed a way to accelerate the speed of reactions. In this context arise the enzymes that are the biological catalysts. Most enzymes are globular proteins. They have specificity (preference) both for their substrates (the molecule that will undergo the chemical reaction) and for the type of reaction on the substrate.
