Document Summary

Energy obtained from chemical bond energy stored in food" and stored/transported in high. Chapter 4: energy energy bonds of carrier molecules (atp and nadh) Electrons and hydrogens in nadh, nadph, fadh2. Coenzymes that carry electrons from one reaction to another: accepts a hydride atom (h-, 2 electrons and a proton) and donates it. Key players in harvesting energy during oxidation of glucose. Nad+ = nicotinamide adenine dinucleotide (vitamin b3) Fad = flavin adenine dinucleotide (vitamin b2) Catabolism: breakdown of complex molecules into simpler ones (by enzymes) Three ways to make atp: substrate level phosphorylation: generate a few atp during glycolysis (initial breakdown/rearrangement of glucose, oxidative phosphorylation (aerobic respiration): energy stored in high-energy electrons of. Nadh and fadh2 are used to produce atp. Electrons from organic fuel molecules in redox reactions are used to pump h+ across a membrane (proton pump) occurs in the mitochondrial membrane.
