Question

_____________ are biocatalysts that speed up the reactions in biosystems.

Answer 1

Enzymes:

1. The reaction in the body occurs with the help of biocatalysts called enzymes as they provide an alternative lower activation energy path and so increase the rate of reactions.
2. They assure the metabolic needs of cells and assist in a great range of life-sustaining biochemical reactions.

Final Answer: Enzymes are biocatalysts that speed up the reactions in biosystems.
