Cell Respiration Vocab Acetyl Coenzyme A??-? A small molecule that carries acetyl functional groups in cells. Composed of an acetyl group attached to a coenzyme A molecule. The starting product of the citric acid cycle. Adenosine Triphosphate (ATP)??-? The molecule from which cells derive energy. Comprised of an adenosine molecule bonded to three phosphates, each phosphate bond contains energy, especially the third bond. By breaking that one bond and reducing ATP to adenosine?diphosphate (ADP), the cell can get the energy to carry out its various processes. Aerobic respiration??-? A metabolic process involving oxygen in the breakdown of glucose.

The Citric Acid Cycle Acetyl Coenzyme A??-? A small molecule that carries acetyl functional groups in cells. Composed of an acetyl group attached to a coenzyme A molecule. The starting product of the citric acid cycle. Acontinase??-? The citric acid cycle enzyme responsible for catalyzing the reaction that converts citric acid to isocitrate with the release of water. Adenisine Triphosphate (ATP)??-? The molecule from which cells derive energy. Comprised of an adenisine molecule bonded to three phosphates, each phosphate bond contains energy, especially the third bond. By breaking that one bond and reducing ATP to adenisine?diphosphate (ADP), the cell can get the energy to carry out its various processes.

Anaerobic Respiration Anaerobic respiration is the process in which a glucose is split into two pyruvates and then transferred to lactic acid or ethyl alcohol depending on the environment, does not use oxygen Anaerobic respiration occurs in the cytoplasm, outside of the mitochondria Lactic Acid Fermentation: Occurs at the time of strenuous activity or exercise to make two additional ATP on top of regular aerobic respiration that produces 38 ATP - Takes place in muscles, or with food products such as yogurt, cheese Does not use oxygen because there is enough oxygen for aerobic respiration however oxygen is now being pumped to the heart so it is not available for anaerobic respiration.
