Ch06CellRespiration Flashcards
The presence of oxygen; requiring oxygen
Aerobic
Occurring without the use of molecular oxygen;
Anaerobic
Catabolic pathways by which electrons are removed from various molecules and passed through intermediate electron carriers to Oxygen, generating water and releasing energy
Cellular Respiration
Formation of ATP in mitochondria and chloroplasts, resulting from the pumping of protons across a membrane (against a gradient of electrical charge and of pH), followed by the return of the protons through a protein channel with ATP synthase activity.
Chemiosmosis
In cellular respiration, a set of chemical reactions whereby acetyl CoA is oxidized to carbon dioxide and hydrogen atoms are stored as NADH and FADH2. Also called the Krebs Cycle
Citric acid cycle
The passage of electrons through a series of proteins with a release of energy which may be captured in a concentration gradient or in Chemical form such as NADH or ATP
Electron transport
The anaerobic degradation of a substance such as glucose to smaller molecules such as lactic acid or alcohol with the extraction of energy
Fermentation
The enzymatic breakdown of glucose to pyruvic acid (pyruvate)
Glycolysis
Relative loss of electrons in a chemical reaction
Oxidation
ATP formation in the mitochondria associated with flow of electrons through the respiratory chain
Oxidative phosphorylation
Conversion of pyruvate to acetyl CoA and CO2 that occurs in the mitochondrial matrix in the presence of O2
Pyruvate oxidation
A chemical reaction in which one reactant becomes oxidized and the other becomes reduced
Redox reaction
Gain of electrons by a chemical reactant
Reduction
How many net ATP are produced in Glycolysis?
2
What is the carbon compound that is a product of Glycolysis?
3C compound Pyruvate (and there’s 2 of them)
