Consider the mechanism of enolase, as indicated below. Which of the following correctly describes the roles of the Mg2+ as illustrated in the figure? (This is a multi- select question). Mg2+ Mg2 Enolase PO3- OH -C-C-H H OH HO H-N-H Lys 345 Glu211 2-Phosphoglycerate bound to enzyme Mg2+ Mg2 PO3- OH C-C-H OH HO H H-N*-H Lys 345 O Glu211 Enolic intermediate HOH PO3- H Phosphoenolpyruvate The metal ion (Mg2+) is helping to stabilize the extra negative charge that developed on the carboxyl group in the enolic intermediate. The metal ion (Mg2+) is serving as a general base, removing a proton in order to improve the quality of the nucleophile. The metal ion (Mg2+) is assisting in the oxidation of the carboxyl carbon through metal ion catalysis. The metal ion (Mg2+) is helping to orient the substrate properly in the active site. The metal ion (Mg2+) is accepting a proton in order to improve the quality of the leaving group.
The classic concept of bond strain is more correctly described in what way? Select the correct response: The transfer of electron from one chemical moiety to another results to decrease in steric hindrance. The chemical bonds of the substrate is distorted due to the presence of metal ions in the vicinity of the active site. The transition state makes better contact with the enzyme than the substrate due to stabilization effect of various moieties in the active site. The electron cloud of the substrate is polarized by more electronegative moieties in the active site.
Given the following reaction, identify the class of the enzyme involved. CH,O-PO, CH,OH 2- OH OH OH OH OH Ó-PO,2- OH OH class: [Select] EPIC Ps Ai

lace the description with the appropriate step in the enzymatic reaction. The enzyme changes shape, resulting in an induced fit between substrate and enzyme. Glucose and galactose are released, and the enzyme is free to bind other substrates. Lactose Galactose Glucose- Substrate: Lactose Enzyme: Lactase 2 1 Enzyme-substrate complex The bond is broken between glucose and galactose 3 The substrate, lactose, binds to the enzyme forming an enzyme- substrate complex
Determine the sequence of a pentadecapeptide using the information below. carboxypeptidase: G aminopeptidase: R enzymatic hydrolysis fragments: TG, CT, SC, CH, CHP, FCT, RP, PIS, QKF, SCH, PME, EQK, KFC all fragments must be visible in the original sequence. Use one-letter abbreviations only. Write the complete answer in 3-aa length fragments
One 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 ?
