Document Summary

Convert light energy to chemical energy to synthesize food compounds. Obtain energy by processing the chemical energy in an organic compound i. e. carbohydrates, proteins or lipids. Microtubules: aerobic needs oxygen, anaerobic does not need oxygen. Redox reactions: reducing agents have extra electrons that can be given away, oxidizing agents take extra electrons from reducing agents, coenzymes are helper molecules, leo goes ger. Nadh is a temporary energy storing molecule. Glucose + atp + hexokinase glucose 6-phosphate + adp. Fructose 6-phosphate + atp + phosphofructokinase fructose 1,6- biphosphate + adp. Fructose 1,6-biphosphate + aldolase dihydroxyacetone phosphate (or + isomerase glyceraldehyde 3-phosphate [favored in cell]) Glyceraldehyde 3-phosphate (g3p) + nad+ + triose phosphate dehydrogenase 1,3-biphosphate glycerate + nadh. 1,3-biphosphate glycerate + adp + phosphoglycerate kinase atp + 3-phosphate glycerate + phosphoglycero multase 2-phospho- glycerate. Phosphoenol-pyruvate + pyruvate kinase + adp pyruvate + atp. Pyruvate, produced in the cell ctosol, is transferred to the mitochondira matrix and is converted to acetyl coa.
