The correct option for given statement is
D I and II only
I. Enzymes are not consumed during a chemical reaction.
II. Enzymes are specific to particular molecules
Explanation:
Enzymes are biological molecules (typically proteins) that considerably speed up the speed of nearly all of the chemical reactions that turn up at intervals cells.They're necessary|important} always and serve a large vary of important functions within the body, like aiding in digestion and metabolism.
Answer:
Only I and II
Explanation:
Enzymes are catalysts that increase the rate of chemical reactions by decreasing the amount of energy needed to activate the chemical reaction.
Enzymes are not consumed during a chemical reaction and, therefore, once an enzyme has finished catalyzing one reaction, it can move on and catalyze another reaction. Enzymes are also specific to particular molecules based on their shape and size. Enzymes do not, however, increase the amount of energy produced by a chemical reaction.
Only I and II are characteristics of enzymes.
