Chapter 09 - cellular respiration: harvesting chemical energy. G of ?686 kcal per mole of glucose: some of this energy is used to produce atp, which can perform cellular work.

When oxygen reacts with the hydrogen from methane to form water, the electrons of the covalent bonds are drawn closer to the oxygen. ?53 kcal/mol: electrons are passed to increasingly electronegative molecules in the chain until they reduce oxygen, the most electronegative receptor.

These are the stages of cellular respiration: a preview: respiration occurs in three metabolic stages: glycolysis, the citric acid cycle, and the electron transport chain and oxidative phosphorylation, glycolysis occurs in the cytoplasm.
