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.

OXIDATIVE PHOSPHORYLATION AND ELECTRON TRANSPORT 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. Electron transport chain??-? Term used to describe the flow of electrons generated by the oxidation of NADH and FADH2. Responsible for establishing an electrochemical gradient across the inner mitochondrial membrane that powers the synthesis of ATP in oxidative phosphorylation.

Cellular Respiration Cellular respiration can be described as a chemical process that breaks bonds in food molecules or transforms chemical energy from organic molecules into ATP. - Only 40% of food energy is extracted and used for cellular work where the other 60% leaves in the form of heat energy ATP= Provides chemical energy for cellular work/processes in the cell. Structure= Composed of complex organic molecule called adenosine with a tail of three phosphate groups and a ribose sugar- pentose (ADP+P=ATP) (ADP is a diphosphate with an adenosine) ATP is recycled from ADP and phosphate through cellular respiration, ADP and P are connected to create ATP to be used for cell processes, ATP is used for cellular work and ADP and P are extracted from food molecules to create ATP again.

Anaerobic respiration

Gavin Morgan 11/19/2015 Chapter 7 2-Point Notes Cells oxidize organic compounds to drive metabolism: 1. First, enzymes break down the large molecules into smaller ones, a process called digestion. Then, other enzymes dismantle these fragments a bit at a time, harvesting energy from C?H and other chemical bonds at each stage. 2. Electrons lost are accompanied by protons, so that what is really lost is a hydrogen atom, not just an electron. Cellular respiration is the complete oxidation of glucose: 1. When the acceptor is oxygen, the process is called aerobic respiration.
