BIOL 260 Study Guide - Midterm Guide: Hindgut Fermentation, Photosynth, Electrochemical Gradient
Document Summary
By eating other organisms; burn some nutrients as fuel, recycle some as building blocks how do plants obtain nutrients: soil, water, sun plants vs. Can synthesize organic materials- plants capture energy from sun, used to fix inorganic carbon from co2 & create carbs, inorganic molecules taken from soil & h2o used to form other key building blocks. Some a. a. can directly enter krebs; mitochondria oxidize many types of nutrients, capture energy (atp) Metabolic processes inefficient: some energy transferred during chemical rxn released as heat- not sufficient to keep body temp above enviro temp (need feathers, fat) Anabolism: synthesize larger molecules from small catabolism: break large molecules to small (release energy)- catabolism supplies energy for anabolism ** some nutrients can"t be made from other nutrients (essential) can only be found in diet/elements directly/indirectly involved in metabolism. Carbonic anyhydrase assists w/ converting co2 + h2o -> h2co3 parietal cells have to move protons against conc.
