Question

enzymes are involved in nearly all metabolic processes. what is the purpose of enzymes? enzymes supply the energy required for chemical reactions. enzymes provide the water and oxygen required for chemical reactions. enzymes cause a chemical reaction to proceed without substrates. enzymes increase the rate of chemical reactions. lactose c₁₂h₂₂o₅ lactase galactose c₆h₁₂o₆ glucose c₆h₁₂o₆

Explanation:

Enzymes are biological catalysts. They lower the activation - energy of chemical reactions, thus increasing the rate of these reactions without being consumed in the process. They do not supply energy, water, or oxygen for reactions, and reactions cannot occur without substrates in the presence of enzymes.

Answer:

D. Enzymes increase the rate of chemical reactions.
