Respiration is a cumulative function of three metabolic stages,________,_________,______.
glycolysis, Krebs cycle, the electron transport chain
Glycolysis and krebs cycle are the ________ pathways that decompose glucose and other organic fuels.
Glycolysis occurs in the _______, and degrades glucose into two molecules of ________.
cytosol, pyruvate
The _______ cycle takes place within in the mitochondrial matrix, and decomposes a derivative of pyruvate to _______.
krebs, carbon dioxide
The electron transport chain accepts electrons from the breakdown products of the first two stages, and passes these molecules from one molecule to another. At the end of the chain, ________ accepts the electron with hydrogen ions to form _______/
oxygen, water.
The energy released at each step is stored in a form the mitochondion can use to make ______. This mode of ______ synthesis is called _______ ________.
ATP, ATP, oxidative phosphorylation
