Study Notes
Enzymes and Cellular Respiration
- Enzymes speed up reaction rates by lowering the activation energy required for the reaction to occur.
- NAD+/NADH and FAD2+/FADH2 are electron carriers that play a crucial role in transferring electrons during cellular respiration.
- Ligase enzymes catalyze the joining of two molecules, forming a new covalent bond.
Cellular Respiration Stages
- The three major stages of cellular respiration are glycolysis, the citric acid cycle, and oxidative phosphorylation.
Glycolysis
- Glycolysis occurs in the cytosol of the cell.
Enzyme Functions
- Oxidoreductase enzymes catalyze oxidation and reduction reactions, facilitating the transfer of electrons.
