What is cellular metabolism?
(ANS- a controlled set of biochemical reactions that occur in living organisms in order to maintain life
What is an enzyme?
(ANS- a protein, or group of proteins, that catalyze (speed up) chemical reactions
What is unique about enzymes?
(ANS- the enzyme is not consumed during the reaction and can be used repeatedly by the cell
What is a cofactor?
(ANS- a small chemical component, usually metal ions, that assist enzymes during the catalysis reactions
Do cofactors serve as regulators of chemical reactions?
(ANS- Yes
In the absence of the proper cofactor what happens?
(ANS- enzymes are inactive
In the presence of the proper cofactor what happens?
(ANS- enzymes are active
In order to produce sufficient levels of energy what must microorganisms do? (ANS- microorganisms must break down complex nutrients into smaller, manageable (and useful) subunits
What 3 things must enzymes break down into smaller subunits?
(ANS- Enzymes must break down proteins, lipids and polysaccharides into their smaller building-block molecules
Fats or lipids get broken down into what?
(ANS- glycerol/fatty acids
Most metabolic processes can be classified as either of what 2 things?
(ANS- catabolism or anabolism
What is catabolism?
(ANS- the process of breaking down larger molecules into useful energy sources
What is anabolism?
(ANS- the building up or biosynthesis of macromolecules from smaller molecular units into larger complexes
The anabolic process is often used during what?
(ANS- growth and repair phases of the cell.
