Answer 1

I'm almost certain the answer you are looking for is "proteins."

Answer 2

Yeah, I agree.

Answer 3

The best answer would be CATALYSTS.

Answer 4

But proteins help regulate a cell, and proteins are macroMOLECULES.

Answer 5

Enzymes are molecules and proteins. However, catalysts are molecules too and may also be proteins. Catalyst would be a better answer because they regulate cells and they also take on enzyme and protein functions.

Answer 6

I'm sure you could argue the answer with whichever one you write, @Santeria.

Answer 7

Only the solution manual would tell you which answer it was looking for.

Answer 8

Proteins, catalysts or macromolecules would all be equally good.
