- 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
- The site of electron transport and oxidative phosphorylation is the _____________
- inner membrane of the mitochondrion.
- for each molecule of glucose degraded to carbon dioxide and water by respiration, the cell makes up to about __ molecules of ___.
- 38 of ATP.
- glycolysis means the splitting of _______. Glucose is then split into two ____-____ sugars, then oxidized and rearranged to make __ pyruvate molecules.
- glucose, three-carbon, 2
- the net energy yield from glycolysis, per glucose molecule is, _ ATP plus _ NADH.
- 2, 2
- No ___ is released during glycolysis, which glycolysis occurs whether or not molecular ___ is present
