Crossword CPA #8 Flashcards
lack of this molecule will force you to use fermentation instead of cellular respiration
final electron acceptor
step of cellular respiration; 2 pyruvic acids are converted into 2 identical molecules that can enter the krebs cycle; step has a net of zero ATPs but 2 co2 are released and 2 NADH are formed
synthesis of Acetyl-CoA
site other than the active site that a noncompetitive inhibitor binds to in/on enzyme
allosteric
type of inhibitor that binds and blocks an enzymes active site; competes with substrate
competitive
type of reaction that breaks molecules down into building blocks; exergonic reaction
catabolic
this happens to the electron acceptor in a redox reaction
reduced
all of the catabolic and anabolic and exchange reactions in the body
metabolism
suffix sometimes added to protein names to indicate thy are enzymes
-ase
chemicals that increase the likelihood of a reaction but are not permanately changed in the process (ie enzymes)
catalysts
step of cellular respiration; electron carriers drop off thier hydrogen ions and electrons here; results in 34 net ATP
electron transport chain
point at which it is not useful to add more substrate/enzymes to a reaction
saturation
light, water, and co2 are used to make glucose, o2, and ATP
photosynthesis
this happens to the electron donor in a redox reaction
oxidized
location in/on enzyme that interacts with a substrate
active site
abbreviation for reactions in which a molecule loses an electron to another molecule
redox
occurs when enzymes lose their 3D structure and no longer functional
denature
type of inhibitor that binds somewhere other than an enzymes active site and causes the active site to change shape to prevent substrate binding
noncompetitive
organism whose final electron acceptor during cellular respiration is o2
aerobic
ie NAD+, NADP+, FAD+
electron carriers
step of cellular respiration; 2 acetyl-CoA molecules are broken down; 4 co2, 2 ATPs, 6 NADH, and 2 FADH2 are released/made
krebs cycle
type of reaction that forms macromolecules; endergonic
anabolic
the molecule in the ETC that creates the bulk of ATPs during cellular respiration
ATP synthase
process in which one glucose molecule can be broken down into 38 ATP
cellular respiration
energy is stored in the bonds of this molecule
ATP
the step that involves the breakdown of glucose into pyruvic acids and results in 2 net ATP and 2 NADH; occurs both in cellular respiration and fermentation
glycolysis
alternative process to cellular respiration; results in only 2 net ATP
fermentation
type of feedback in which an enzymes end product can inhibit the enzyme from functioning; used to maintain homeostasis
negative
the amount of energy needed to trigger a chemical reaction
activation energy
type of reaction that uses ATP
endergonic
type of reaction that results in the formation of ATP
exergonic
organic molecules that lower the activation energy needed for a reaction
enzymes
organisms whose final electron acceptor during cellular respiration in NOT o2; forms nitrogen gas, sulfide gas, or methane gas
anaerobic
fits in an enzymes active site
substrate
