Catabolic
Reactions that break down food to get energy
Anabolic
Reactions that result in net energy storage within cells
Metabolic Efficiency
Amount of energy captured in a usable form per amount of energy in starting molecule
Metabolic Rate
Animals’s overall rate of energy use, measured by rate of oxygen consumption
Recovery Metabolism
Animals use metabolic energy to try to reestablish resting membrane potential -> elevated consumption of oxygen after finishing an activity
Endotherm
Animals that produce most of their own heat through metabolic reactions
Ectotherms
Animals that obtain most of their heat from environment
Essential Amino Acid
Can’t be synthesized by organism’s cellular pathways
Peristalsis
Waves of smooth muscle contraction and relaxation
