Study Notes
Metabolic Processes
- Anabolism is the process of building molecules, requiring energy to construct molecules from smaller units.
- Catabolism is primarily responsible for breaking down molecules to release energy.
Lipids in Biological Membranes
- Phospholipids, cholesterol, and glycolipids are representatives of lipids that are part of biological membranes.
- Membrane lipids are typically in a liquid state at physiological temperatures.
Signal Transduction
- Receptors for primary messengers are located on the cell surface or within the cell.
Cellular Respiration
- Cytochrome c oxidase is the enzyme responsible for transferring electrons to oxygen during oxidative phosphorylation.
- Glucokinase activity is found in the liver.
- The main extramitochondrial source of NADH2 for the electron transport chain (ETC) is glycolysis.
- ATP synthase is the enzyme that synthesizes ATP during oxidative phosphorylation.
The Tricarboxylic Acid (TCA) Cycle
- Acetyl-CoA is the metabolite utilized in the tricarboxylic acid (TCA) cycle.
