Question 1 pts
What is cellular metabolism?
Your Answer:
Cell metabolism is the sum of all chemical reactions that occur in the cell.
Metabolism is a controlled set of biochemical reactions that occur
in living organisms in order to maintain life.
Question 2 pts

Enzymes are proteins that speed up/catalyze chemical reactions, they are
regulated by cofactors, which are small metal ions. Without a cofactor, the
enzyme is inactive.
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 pts
What is the difference between catabolism and anabolism?
Your Answer:
Catabolism breaks down molecules from food. It releases energy while
relying on oxidative coenzymes to oxidize intermediates. Anabolism builds
up macromolecules from the precursor molecules made by catabolic
pathways. It consumes energy while relying on reduced coenzymes to
reduce intermediates.
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.
