Chemistry Flashcards
Where do the ETC and Krebs occur?
mitochondria
Are the ETS and Krebs aerobic or anaerobic?
aerobic (requires O2)
Where does glycolysis occur?
in the cytosol
Is glycolysis aerobic or anaerobic?
anaerobic (doesn’t require oxygen)
A catalyst that lowers activation energy. Does NOT alter equilibrium.
enzyme
An inactive enzyme precursor
pro-enzyme (zymogen)
Protein component of an enzyme, where coenzyme attach
apoenzyme
What type of reactions are affected by substrate concentration, pH, and temperature.
enzymatic
An enzyme that causes oxygen in a compound to be change by water
oxidase
Removes a hydrogen
dehydrogenase
What enzyme adds hydrogen to a compound?
reductase
Enzyme which catalyzes the addition of a carboxyl group
carboxylase
Enzyme that catalyzes the release of CO2 from compounds is called?
decarboxylase
enzyme that facilitates hydrolysis as in sucrase in the breakdown of sucrose is called?
hydrolase (cleavage of a compound by the addition of water)
enzyme which adds inorganic phosphate to a substrate without using ATP is called?
phosphorylase
enzyme that removes a phosphate group from its substate by hydrolyzing phosphoric acid monoester into a phosphate ion and a molecule with a free hydroxyl group is called?
phosphatase
Enzyme that transfers a phosphate group from high energy donor molecules like ATP
kinase
Enzyme which changes the configuration and not the composition of a compound, Glucose ^ phosphate into Fructose 6 Phosphate
isomerase
a type of isomerase which moves one group to another part in the same chemical compound like phosphate from C3 to C2 in 3-phosphoglycerate to 2-phosphoglycerate
mutase
enzyme that catalyzes the transfer of a functional group from one molecule to another
transferase
enzyme that catalyzes the joining of two molecules
ligase
Refers to the maximum velocity of a reaction and is proportional to enzyme concentration
Vmax
is the substrate concentration required to reach 1/2 of the Vmax
Kmax (Michaelis-Menten constant)
