Unit 6 Homework Flashcards
Enzymes speed reactions mainly by:
lowering activation energy
The names of enzymes commonly end in:
-ase
The active site of an enzyme is the region that:
is involved in the catalytic reaction of the enzyme
The components of the nucleotide ATP are:
adenine, ribose, and three phosphate groups
The chemical addition of a phosphate group to an organic molecule occurs in the process of:
phosphorylation
Regulation of enzyme activity through the conversion of the enzyme into active and inactive forms is known as:
allosteric regulation
A chemical reaction in which the reaction end products have more free energy than the reactants is known as a(n):
endergonic reaction
The enzyme that catalyzes the hydrolysis of sucrose into glucose & fructose is:
sucrase
Regulation of enzyme activity that occurs when an enzyme’s activity is inhibited by the buildup of the enzyme’s end product is known as:
feedback inhibition
Our current model of enzyme function is the:
induced-fit model
