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

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.
