Flashcards from the chapter 8 textbook notes

Terms

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.
