Cards

Term
Deamination
Definition
Process of which amine groups are split off from amino acids
Term
Noncyclic Photophosphorylation
Definition
The production of ATP by noncyclic eletron flow
Term
Anaerobic Respiration
Definition
Type of cellular respiration no requiring oxygen atoms as final electron acceptors
Term
NADP+
What is it?
Definition
Nicotinamide Adenine DinucleotidePhosphate
Important vitamin-derived electron carrier molecule
Term
Ribozyme
Definition
RNA Molecule functioning as an Enzyme
Term
FAD
What is it
Definition
Flavine Adenine Dinucleotide
Important vitamin-derived electron carrier molecule
Term
Feedback Inhibitition
Definition
Negative feedback\ Method of controlling the action of enzymes in which the end-product of a series of reactions inhibits an enzyme in an earlier part of the pathway.
Term
1.Catabolism
2. Catabolism Pathway
3. Exergonic
Definition
1.All of the decomposition reactions in a organism taken together 2. Break larger molecules into smaller products 3. Releases more energy than it needs.
Term
Electron Transport Chain
Definition
Series of redox reactions that pass electrons from one membrane-bound carrier to another, and then to a final electron acceptor.
Term
Calvin-Benson Cycle
Definition
Stage of photosynthesis in which atomspheric carbon dioxide is fixed & reduced to produce glucose.
Term
Metabolism
Definition
the sum of all chem. Rx, both anabolic & catabolic, w/in an organism.
Term
Chemiosmosis
Definition
Use of ion gradients to generate ATP
Term
Photophosphorlation
Definition
use of NRG from light to attach inorganic phosphate to ADP
Term
Noncompetitive Inhibitor
Definition
inhibitory substance that blocks enzyme activity by binding to an allosteric site located elsewhere on the enzyme
Term
Acetyl-CoA
Definition
Combination of 2 carbons from pyruvic acid and co-enzyme A
Term
Precursor Metabolite
Definition
Any of 12 molecules typically generated by catabolic pathway & Essential to the synthesis of organic macromolecules in many bacterial cells
Term
Krebs Cycle
Definition
Series of 8 enzymatically catalyzed reactions that transfer stored energy from acetyl-CoA to coenzymes NAD+ and FAD
Term
Glycolysis (Embden-Meyerhof Pathway)
Definition
First step in the catabolism of glucose via repiration and fermentation
Term
pathway
Definition
a series of reactions catabolism or anabolism
Term
1. Anabolism Pathway
Definition
Synthesize large molecules from the smaller products of catobolism and they use the building blocks & ATP to synthesiae macromolecules needed fro groath and reproduction
Term
Endergonic
Definition
Requires more energy than it produces
Term
Redox Reactions
Another name?
Definition
Electron transfers of : Transfer of electrons from a molecule that donates an electron to a molecule that accepts an electron.
