Chapter 8 Vocab Flashcards
Acidic fermentation
An anaerobic degradation of pyruvic acid that results in organic acid production
Active site
The specific region on an apoenzyme that binds a substrate. The site for reaction catalyst
Aerobic respiration
Respiration in which the final electron acceptor in the electron transport chain is oxygen
amination
The addition of amine group to a molecule
Amphiobolism
Pertaining to the metabolic pathways that serve multiple functions in the breakdown, synthesis, and conversion of metabolites
Anabolism
The energy consuming process of incorporating nutrients into Protoplasm through biosynthesis/ making smaller molecules into bigger ones
Anaerobic respiration
Respiration in which the final electron acceptor in the electron transport chain is an inorganic molecule containing sulfate, nitrate, nitrate, carbonate and other salts, rather than molecular oxygen gas
Anoxygenic
Any reaction that does not produce oxygen; usually in reference to the type of photosynthesis occurring in anaerobic photosynthetic bacteria
apoenzyme
The protein part of an enzyme, as opposed to the non-protein or inorganic cofactors
ATP
adenosine triphosphate - cell energy
ATP synthase
A unique enzyme located in the mitochondrial cristae, bacterial cell membrane, and chloroplast grana that harnesses the flux of hydrogen ions to the synthesis of ATP
Beta oxidation
the degradation of long chain fatty acids. Two carbon fragments are formed as a result of enzymatic attack directed against the second or beta carbon of the hydrocarbon chain. Aided by CoA, the fragments enter the tricarboxylitic acid cycle and are processed for ATP synthesis
Bioenergetics
The study of the production and use of energy by cells
Catabolism
The chemical breakdown of complex compounds into simpler units to be used in cell metabolism
Catalytic site
The niche in an enzyme where the substrate is converted to the product (also active site)
Chemiosmosis
The movement of ions across a semi permeable membrane
Coenzymes
A complex organic molecule, several of which are derived from vitamins. A ___________ operates in conjunction with an enzyme. They serve as transient carriers of specific Adams or functional groups during metabolic reactions
Cofactor
An enzyme accessory. It can be organic, such as coenzymes, or in organic such as Fe2+, Mn2+. Or other metallic ions
Competitive inhibition
The blockage of microbial growth because of metabolic analog drug that inserts on the active site of an essential metabolic enzyme and prevents further action of the enzyme
Cytochromes
A group of heme protein compounds whose chief role is an electron and or hydrogen transport occurring in the last phase of aerobic respiration
