- Which of the following statements is/are correct?a) Enzyme quantities depend on the rate of their synthesis and degradationb) Enzyme quantity is decreased if an amino-acid involved in the catalytic activity is modifiedc) Protein kinase A activity is regulated through protein interaction.d) Kinases control the activity of other enzymes by covalent modification; irreversiblephosphorylation explain each of the following optionarrow_forwardIn an enzyme's active site, a catalytic histidine residue abstracts a proton from the hydroxyl group of a catalytic serine residue. The catalytic serine then performs a nucleophilic attack on the carbonyl carbon of a peptide bond (on the substrate). The final products of this reaction are a cleaved substrate at the peptide bond, with a new amino group and carboxyl group, and regenerated catalytic residues. In this reaction, the serine residue is displaying what? A. Proximity and Orientation B. Covalent catalysis C. Metal ion catalysis D .A and B E. B and C F. None stated herearrow_forwardWhat happens to a denatured enzyme regarding its functionality? How can that result be explained with the help of the lock and key model?arrow_forward
- The binding of Protein X to the active site of an enzyme represents which type of enzyme regulation? Protein X Enzyme a) b) allosteric regulation zymogen activation feed-back inhibition modulator proteins regulation by isozymes Active Sitearrow_forwardWhere is the active site for this enzyme located?arrow_forwardOne way of expressing the rate at which an enzyme can catalyze a reaction is to state its turnover number. The turnover number is the maximum number of substrate molecules that can be acted on by one molecule of enzyme per unit of time. The table gives the turnover number of four representative enzymes. Enzyme Substrate Turnover number (per second) Ribonuclease RNA 100 Fumarase fumarate 800 Lactate dehydrogenase lactate 1000 Urease urea 10,000 How many molecules of urea can one molecule of urease act on in 12.0 min ?arrow_forward
- There are many metabolic pathways in a biological system, and it is critical to regulate these pathways so that only particular pathways are active at a single time. Which enzyme would be in the regulation point in the hypothetical pathway shown below. A¹B 2C 3 D4E A) A → B B) B-C C) C-D D) D→ E E) The regulation point is highly dependent upon the metabolic pathway.arrow_forwardMany biosynthetic pathways are regulated by feedback control, where the product of a pathway turns off an enzyme that catalyzes an early step in the pathway. Usually, this control comes from an allosteric interaction. Of the types of reversible enzyme inhibition (Competitive inhibition, Noncompetitive inhibition, and Uncompetitive inhibition), what type is most likely to occur in a feedback control mechanism like this and why?arrow_forwardA single celled, prokaryote organism has the ability to use the Na+/K+ pump in their cell membrane to move Na+ out of the cell and K+ into the cell. The Na+ /K+ pump is an example of a functional protein because it a) is a Polypeptide presents specific shapes that interact with (binds with) specific molecules, b) uses electrical interactions with these molecules to produce change in its shape or motion. C) interacts with specific molecules based on the fit of the molecule into specific active sites in the protein, d) As a result of the interaction with specific molecules, it can bind with ATP and use the bond energy in the ATP molecule to move the target molecule(s). e) all the answers are true.arrow_forward
