CELLULAR RESIPRATION I. Overview of the oxidation of Glucose What kinds of cells carry out aerobic cellular respiration? -Most eukaryotes and prokaryotes Why do you breathe? Eat? -To obtain energy from food and use oxygen to create water Oxidation C 6 H 12 O 6 + 6O 2 + 6 H 2 O → 6CO 2 + 6 H 2 O + energy (in the chemical bonds of ATP) Reduction -aerobic Respiration is a redox reaction -glucose → oxidation → carbon dioxide -oxygen → reduction → water -happens in multiple steps II. Steps of aerobic respiration (Note: these reactions do not occur in separate cellular compartments in prokaryotes) A. Cytosol – Glycolysis Rank the following with respect to their energy value in metabolism: two pyruvates: one glucose; one fructose 1,6 bisphosphate, two glyceraldehydes 3-phosphates (G3P). In what forms is energy captured in glycolysis? How is energy captured? -ATP (directly) And -NADH (which is then used to make ATP) Glycolysis (means breaking of sugar) (occurs in cytosol and everything else is in the mitochondria)
