select the correct statement(s) about enzymes. enzymes are proteins. enzymes are not substrate specific. enzymes decrease activation energy. all enzymes work at a ph of 7. enzymes decrease the rates of biochemical reactions.

Answer

Brief Explanations:

  • While most enzymes are proteins, some are RNA - ribozymes. So "Enzymes are proteins" is not always true.
  • Enzymes are highly substrate - specific.
  • Enzymes are biological catalysts that decrease the activation energy required for a biochemical reaction to occur.
  • Different enzymes have different optimal pH values, not all work at pH 7.
  • Enzymes increase the rates of biochemical reactions, not decrease them.

Answer:

Enzymes decrease activation energy.
