CELLULAR RESPIRATION

FERMENTATION

________: an expansion of glycolysis in which ATP is generated by substrate level phosphorylation.

PHOSPHOFUCTOCKINASE

________: allosteric enzyme that functions early in the pathway of glycolysis and acts as a regulator of respiration it is inhibited by high levels ATP.

GLYCOLYSIS

________: (occurs in the cystol) the degradation of glucose begins as it is broken down into two pyruvate molecules.

CHEMIOSMOSIS

________: energy- coupling mechanism that uses energy stored in the form of an H+ gradient to drive cellular work.

AEROBIC RESPIRATION

________: most efficient and is when oxygen is consumed as a reactant along with organic fuel.

FERMETATION

________: the partial degradation of sugars that occur without the use of oxygen.

ANAEROBIC RESPIRATION

________: by certain prokaryotes generates ATP without oxygen using an electron transport chain.

REDUCTION

________: the gain of one of more electrons (gain of energy)

FACULATIVE ANAEROBES

________: can make ATP with oxygen and then switch to fermentation.

OBLIGATE ANAEROBES

________: can not survive in the presence of oxygen glycolysis and the citric acid cycle connect to many other metabolic pathways.

ELECTRON TRANSPORT CHAIN

________: electron transport and pumping of protons which create an H+ gradient across the membrane.

CITRIC ACID CYCLE

________: the cycle that breaks down glucose and releases CO2 as a waste product products of each cycle: 2CO2, 3NADH, 1FADH, 1ATP.
