Chapter 5:Cellular Respiration

doesn't require oxygen. the substrate may be only partly decomposed, releasing less energy, or a nitrogen or sulfur comound may susbtitue for oxygen.

requires oxygen. the oxygen is the oxidizing agent that receives electrons from the decomposed substrates.

glucose is broken down.

carry hydrogen in cells.

produced in lactic-acid fermantaion.occurs in muscle cells

pyruvic acid gets converted in this before the Krebs cycle.

required to start cell respiration and is produced.energy storing molecule

ETS consists of a series of easily reduced and oxidized enzymes and other protiens.embedded in the inner membranes of mitochondria.

loss of electrons

gain of electrons

completes the oxidation of glucose to CO2

energy storing molecule

3-caron compounds

combines with acetate to produce acetly CoA

pruduces a lot of ATP. final step in cell respiration

anaerobic pathway of cellular respiration that converts pyruvate into either lactic acid or ethyl alcohol and carbon dioxide
