4.2 Chemical Reactions Flashcards
What is metabolism on a cellular level?
The sum of all chemical reactions in one cell
What is catabolism?
Processes which break larger molecules into smaller ones.
What is anabolism?
Processes which build up larger molecules from smaller ones.
How does catabolism interact with energy?
Catabolism releases energy
How does anabolism interact with energy?
Anabolism requires input of energy
What is an endogernic reaction?
A chemical reaction that requires a net input of energy
What is an exergonic reaction?
A chemical reaction which releases energy; and products contain less energy than reactants
What is oxidation-reduction reaction?
Chemical reaction in which one reactant is oxidized and another is reduced
What is oxidation?
The loss of one or more electrons
What is reduction?
The gain of one or more electrons
