M2: Module 2 Review
Question 1
What is cellular metabolism?
Your Answer:
All metabolic processes in the cell, energy from food is used to make ATP and energy is
transferred by moving electrons
Metabolism is a controlled set of biochemical reactions that occur in living organisms in
order to maintain life.
Question 2
What is the primary function of enzymes, and how are they regulated?
Your Answer:
Enzymes help speed up chemical reactions in the human body
Enzymes speed up chemical reactions. Most notably, the enzyme is not consumed
during the reaction and can be used repeatedly by the cell. Enzymes can also be
regulated by a cofactor such that in the absence of the proper cofactor, enzymes are
inactive while in its presence enzymes are active.
Question 3
What is the difference between catabolism and anabolism?
Your Answer:
Anabolism refers to the process which builds molecules the body needs; it usually
requires energy for completion. Catabolism refers to the process that breaks down
complex molecules into smaller molecules; it usually releases energy for the organism
to use.
Catabolism is the process of breaking down larger molecules into useful energy sources
whereas anabolism is the building up or biosynthesis of macromolecules from smaller
molecular units into larger complexes, most often associated with cellular growth and
repair.
