Select all that apply. enzymes are not required to sustain the life of an organism act as catalysts in chemical reactions of cells interact with specific substrates like a lock and key can lower the required activation energy for reactions in living organisms

The right answers are B, C and D.

An enzyme is a protein with catalytic properties. Virtually all biomolecules capable of catalyzing chemical reactions in cells are enzymes; some catalytic biomolecules, however, consist of RNA and are therefore distinct enzymes: they are ribozymes.

An enzyme acts by lowering the activation energy of a chemical reaction, which increases the rate of reaction.

b,c,d

Explanation:

i think the answer is b.

it's not c. i took the quiz and got it wrong. so my best guess is b.

have a great day, and hope this .
