Question

Which statement about a biological catalyst is true. A. Catalysts increase the velocity of chemical reactions. B. Catalysts shift the equilibrium of a given reaction towards the products. C. Catalysts are used up during a chemical reaction. D. Catalysts change the thermodynamic favorability of a reaction.

Answer 1

c

Step-by-step explanation:

catalysts are used up in a chemical reactiob

Answer 2

The right answer to this question is option A. Catalysts increase the velocity of chemical reactions.

Step-by-step explanation:

Catalysts can be lots of things, it can be a specific substance to a chemical reaction that helps this reaction to happen faster, or even an enzyme. A catalyst, or, a biological catalyst, is mostly recognized as enzymes, and enzymes work in a system called lock-key system. So for the reaction to happen, a specific substrate needs to enter in a specific enzyme, and when that happens, the reaction happens faster than before.
