10
New cards

metabolism

the sum of all chemical reactions that occur in a cell to carry out the essential processes of life

11
New cards

catabolism

breaks down complex reactions and releases energy

anabolism

building reactions that require energy

13
New cards

enzymes

proteins that increase rate of chemical reactions, works by lowering the activation energy
