Enzyme Functions & Basics
Enzymes are macromolecules that work as these
What is a biological catalyst?
What kind of cycles do enzymes use to make reactions? (Hint: It's in the name of this section)
What are Catalytic cycles?
What is an optimal condition?
Mimics that reduce enzyme productivity by blocking substrates from entering the active site
What are competitive inhibitors?
Where is pepsin located?
What is the stomach?
Enzymes work as catalysts by lowering what
What is activation energy?
Are metabolic reactions reversible?
What is yes?
What part of the enzymes are sensitive to the environment?
What are the proteins?
Do not directly compete with the substrate, but bind to another part of the enzyme
What are noncompetitive inhibitors?
Where is trypsin located?
What is the intestine
The reactant to which an enzyme binds
What is a substrate?
What kinds of bonds hold substrates in the active site?
What are hydrogen or ionic bonds?
What happens when enzymes are not in their optimal range?
What is denaturation?
Any case in which a protein's function at one site is affected by the binding of a regulatory molecule to a separate site
What is allosteric regulation?
What does amylase catalyze?
What are straches?
Where the enzyme binds to the substrate
What is the active site?
Are the reverse reactions of enzymes equal to the initial ones?
What two factors influence enzyme activity?
What are pH and temperature?
The mechanism that amplifies a response of enzymes to substrates
What is cooperativity?
What does lipase catalyze? (Hint: think LIPids)
What are fats?
The specific shape shared by the enzyme and substrate making them only compatible with each other
What is induced fit?
Parts of the amino acids that make up the active site
What is the R group?
What is the optimal pH of MOST enzymes?
What is 6-8
A metabolic pathway is switched off by the inhibitory binding of its end product to an enzyme that acts early in the pathway
What is feedback inhibition?
What does maltase catalyze (Hint: just change one letter)
What is maltose?
