|
cellular respiration
|
Process that releases energy by breaking down glucose and other food molecules in the presence of oxygen
|
Aerobic
|
Process that requires oxygen
|
NAD+
|
electron carrier involved in glycolysis
|
FAD
|
electron carrier produced during the Krebs cycle
|
Glycolysis
|
A metabolic process that breaks down carbohydrates and sugars through a series of reactions to either pyruvic acid or lactic acid and release energy for the body in the form of ATP
|
Anaerobic
|
Process that does not require oxygen
|
prepartory reaction
|
parent drug more polar metabolite
|
citric acid cycle
|
Completes the breakdown of glucose by oxidizing a derivative of pyruvate to carbon dioxide.
|
Electron Transport Chain (ETC)
|
series of electron carrier proteins that shuttle high-energy electrons during ATP-generating reactions
|
substrate-level phosphorylation
|
The enzyme-catalyzed formation of ATP by direct transfer of a phosphate group to ADP from an intermediate substrate in catabolism.
|
Fermentation
|
A catabolic process that makes a limited amount of ATP from glucose without an electron transport chain and that produces a characteristic end product, such as ethyl alcohol or lactic acid.
|
oxygen dept
|
amount of oxygen requirement to oxidize lactic acid produced anaerobically during strenous muscle activity.
|
Mitocondrion
|
Cell organelle that converts the chemical energy stored in food into compounds that are more convenient for the cell to use
|
Acetyl CoA
|
the entry compound for the citric acid cycle in cellular respiration, formed from a fragment of pyruvate attached to a coenzyme
|
Cytochromes
|
proteins that play a key role in electron transport chains in mitochondria and chloroplasts
|
Chemiosmosis
|
Process by which a Hydrogen pump pumps protons into the thylakoid membrane. H+ passively flows through the ATP synthase which leads to the creation of ATP.
|
Catabolism
|
Metabolic pathways that break down molecules, releasing energy.
|
Anabolism
|
Metabolic pathways that construct molecules, requiring energy.
