An enzyme that is catalytically inactive unless it is acted upon by a protease is called: a prosthetic group a coenzyme a restriction enzyme a holoenzyme a zymogen
(a.) An enzyme that requires a nucleotide triphosphate such as ATP to couple with an unfavorable reaction is called a: zymogen transferase ligase (b.) An enzyme that has its polypeptide chain but not its cofactor is called a(n): apoenzyme empty enzyme absent enzyme lyase
25 Blood coagulation involves: A) a kinase cascade. B) zymogen activation. C) serine proteases. D) both a kinase cascade and zymogen activation. E) both zymogen activation and serine proteases.
Compare and contrast the activity of enzyme inhibitors and co-enzymes and their function in regulating enzymes.
Which of the following activates a zymogen? Choose one: O A. Chymotrypsinogen O B. Enterokinase O C. Pepsinogen O D. Trypsinogen
[Biochemistry] Compare phosphorylation and proteolysis as mechanism for activating an enzyme. Explain why a lipid hormone have intracellular receptors.
Compare/Contrast the following: protein/enzyme, ligand/substrate, channel protein/carrier protein, exocytosis/endocytosis.
1. Define zymogen. Why are these forms necessary? 2. The principle role of Hb is to deliver oxygen to working tissues. a)Calculate the volume of oxygen (in mLO2 per 100 mL blood)delivered to systemic tissues at rest. b)Calculate the volume of oxygen (in mLO2per 100 mL blood) delivered to exercising muscle tissue.(explain your reasoning/show calculations in (a+b) for partial credit if warranted) c)Why is this change in delivery important to maintain animal function?
Compare competitive and noncompetitive inhibition Question An enzyme is placed in the presence of an unknown substance to determine whether the substance is an inhibitor. As the substrate concentration is increased, the rate of reaction is compared to the normal rate of reaction. Initially, the rate is equal to normal, and as the substrate concentration is increased more and more, the rate of reaction remains the same as the normal rate. What can be concluded about the unknown substance? Select...
Compare competitive and noncompetitive inhibition Question An enzyme is placed in the presence of an unknown substance to determine whether the substance is an inhibitor. As the substrate concentration is increased, the rate of reaction is compared to the normal rate of reaction. Initially, the rate is slower than normal, but as the substrate concentration is increased more and more, the rate of reaction approaches normal. What can be concluded about the unknown substance? Select the correct answer below: O...
