Question

question 11
the process of constructing large molecules is known as
a catabolism.
b metabolism.
c anabolism.
d lysis.
e evolution.
question 12
one way a vitamin can act as a coenzyme is to.
a bind to a substrate to help it find its enzyme.
b bind to the enzyme so the enzyme can change its shape and bind to its substrate.
c bind to the outside of a cell, so an enzyme can enter and carry out reactions.
d bind to another vitamin, signaling a cell to activate its enzymes.
e replace the activation - energy - lowering activity of a missing enzyme.

Explanation:

For Question 11, anabolism is the process of building large molecules from smaller ones. Catabolism breaks down molecules, metabolism is all chemical reactions in an organism, lysis is the breaking - down of cells, and evolution is related to species change over time.
For Question 12, coenzymes like vitamins bind to enzymes to help them change shape and bind to substrates. They don't bind to substrates to find enzymes, bind to cell - exteriors for enzyme entry, bind vitamins to signal cell activation, or replace enzyme activity.

Answer:

Question 11: C. anabolism
Question 12: B. bind to the enzyme so the enzyme can change its shape and bind to its substrate.
