Document Summary
Photosynthesis produces organic molecules and oxygen and we can eat the plants or eat the animals that eat the plants to gain that energy. When we breath out co2, the plants use that. Thermodynamics in photosynthesis - energy can be transferred or transformed but not destroyed. Solar energy- potential and kinetic energy and chemical energy electrons- protons- chemical potential energy of atp. Objective- describe the overall method and goal of aerobic cellular respiration aerobic cellular respiration- electrons are transferred from c-c and c-h bonds in energy rich molecules to o2. The energy of those electrons is used indirectly to generate. Atp during oxidative phosphorylation. (fire is when c-c goes directly to o2 that"s (cid:449)hy (cid:449)e ha(cid:448)e a slo(cid:449) regulated process to pass the electrons slo(cid:449)ly so (cid:449)e do not combust. ) Objective: in a biochemical reaction scheme, identify which compounds and atoms are oxidized and which are reduced. Lose electrons oxidation, gain electrons reduction leo ger.
