Document Summary
Week 1 (lecture 1, lecture 2 (read ch 7), lecture 3 (read ch 14/15)) Energy tissue level: fatty acids, glucose, ketone bodies. Energy stores: glycogen ( glucose) and triacylglycerol ( fatty acid) Building blocks: amino acids, dna bases, fatty acids, isoprenoids. Adapts when resources and stores are scarce (ex. starvation) Liver provides energies to other organs from its storages. Brain and muscles use ketone bodies (from liver) *** know pathways and functions **: glycogen synthesis short term energy storage, triglyceride biosynthesis long term energy storage. Organ specialization (ex. liver which carries out all metabolic pathways vs. brain which only metabolizes glucose) Cell vs. intercellular (ex. hormones) regulation: enzyme activity fluctuates (short term) and is affected by allosteric effectors, enzyme amount is more stable (long term) and is affected by hormones and diet. Metabolism: liver glucagon (alpha cell) stimulates glucose synthesis and export, muscle insulin (beta cell) stimulates glucose reuptake and consumption.
