in a chemical reaction bonds in the reactants molecules are broken and new bonds are formed to yield products. how does an enzyme make this happen an optimal rate in a cell?

A. It increases the amount of energy needed to break the bonds in the substrate.

Explanation:

Enzymes are known to be protein-based catalyst. It helps to speed up the chemical reactions that take place in the human body. They actually bind molecules and work in ways to alter chemical reactions. These enzymes are needed for food digestion, reproduction, healing diseases, blood coagulation, etc.

Enzymes help to increase the rate of reaction by lowering the activation energy. Certain enzymes can work to convert substrate to product at million of times faster. As a catalyst, it increases the energy needed to break bonds found in the substrate. This makes the reaction to occur at a faster rate.

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up
