Slide 1Metabolism 2 Slide 2Metabolism 2Metabolic RateDefinitionGrowth StorageRepairMetabolic rate is the rate at which an animal Heatdegrades chemical energy from foodstuffs into heat energyWorkPotential energyGametes milk mucous hair etc but also urea egAnimals are constant consuming chemical energy it flows through the animal and most gets absorbed but some get wastedFocusing on absorbed energy and what its fate is 3 fatesMetabolism We will take the energy and oxidase compoundsagain some of the energy will be lost as heat to the environmentBiosynthesis We take energy to build molecules we do this to store energy or build new compounds to grow Again some of the energy will be lost as heat instead of being put into the chemical bonds to the environmentThe molecules we make we do other things too Maybe we metabolize them grow store repiarWork Used to do work Ultimately all the energy used for energy will be lost as heat eventually The purpose is the diagram shows that we consume chemical energy food it may go through different processes as said before But ultametly in the end it becomes heat Gametes milk mucous hair etc but also urea eg Concept of metabolic rate Animals are constantly ingesting chemical energy Much of the chemical energy will be absorbed Some of it is wasted fecal chemical energy 2 major fates for absorbing chemical energy metabolism in the stomach area on the picture Metabolism losing heat in the environment The next fate is biosynthesis to build lipids phospholipids proteins etc To allow growth storage fatty acid triglyceride storage or for repair Biosynthesis also is not completely efficient and also leads to heat production Next fate is workmovement ultimately all the energy used for work eventually releases heat is some way shape or form Main thing to get from the diagram is taking ingested chemical energy eventually goes through different immediate forms but eventually ends up as heat 3 major fates for absorbed energy metabolism biosynthesis and workNot 100 efficient as heat is always produced
