Document Summary

Starts with energy from the sun, use energy to do work. Plants: h2o+co2 c6h12o6+o2, glucose starch in plants turn energy into cellular energy, c6h12o6+o2 h2o+co2 and energy. Energy metabolism: process of converting energy from carbon hydrogen bonds to phosphate bonds, atp: form of energy. Glycolysis: in cytoplasm, glucose (6 carbon sugar) is broken down 2 pyruvic acid (3 carbon) Can be converted into lactic acid (3 carbon, different config: pyruvic can"t leave cell but lactic acid can. Kreb"s cycle: chemical reactions that take acetyl coa, transforms acetyl coa taken back to acetyl coa, process rips co2 and h+ Produces atp, adp+p atp (energy coming from food) Pyruvate acetyl coa (2 carbon sugar: requires enzyme called coa. Acetyl coa binds with oxaloacetate citrate (6 carbon: citrate. Release co2 nadh: alpha-ketoglutarate (5 c) Adp+p atp: fmn+ fmnh takes h+ from nadh, fadh fad, oxidized cytochrome. Take the rest of energy from all components reduced cytochrome.
