Document Summary
How does energy flow through animals: all animals are chemoheterotrophic and holozoic, food is source of energy and carbon , ingest and digest. U(cid:374)til it goes fro(cid:373) gut i(cid:374)to (cid:455)ou, it is(cid:374)"t part of (cid:455)ou. Fat is where excess energy is stored: store lots of energy without storing as much weight, lipids are more reduced more electrons on them that can be puled off. Carbs and proteins when stored, half the weight is water as they are hydrophilic: lipids are hydrophobic, so nearly no water when storing them. Store energy when excess atp is available. Biosynthesis - build biological molecules for growth: new, bigger cells, new dna, maintenance and growth. Atp conversion work f x d = + . Work is a combination of the kinetic and physical energy exerted by an object: heart does work blood rubs against vessel walls friction, heart pumps so that it can go through the vessels.
