Concept explainers
(a)
Interpretation:
Whether sucrose is enzyme or not has to be determined.
Concept Introduction:
Enzymes are proteins that serve as biological catalysts for biochemical reactions in organisms. They can enhance
(1) Hydrolase: Enzyme that catalyzes hydrolysis reaction. They can be subdivided into lipase that hydrolyzes ester bond in lipids and proteases that hydrolyze proteins.
(2) Dehydrogenase: Enzyme that catalyzes dehydrogenation reaction.
(3) Oxidases: Enzymes that catalyze oxidation reactions.
Mostly name of enzymes end with suffix
(b)
Interpretation:
Whether sucrase is enzyme or not has to be determined.

- The first step of the metabolic process known as glycolysis is the conversion of glucose to glucose- 6-phosphate. This process has a positive value for rG' Glucose + Pi Glucose-6-phosphate + H2O rG' = +13.8 kJ/mol-rxn This reaction is coupled to the hydrolysis of ATP ATP + H2O ADP + Pi rG' = -30.5 kJ/mol-rxn What is the sum of these two equations and the value of rG' for the coupled reaction? Is the coupled reaction product-favored at equilibrium?arrow_forwardWhat is the general role of enzymes in the human body?arrow_forwardWhy are enzymes that are used for laboratory or clinical work stored in refrigerators?arrow_forward
- A solution of the enzyme glycogen synthase incubated at 45°C lost 70% of its activity in 3 minutes „but when incubated at 45°C in the presence of a very large concentration of its substrate UDP- Glucose, it lost only 3% of its activity in the same amount of time, Why? Clu CH,OH CH, OH HO, он CH;OH CH2OH но HO он HO UDP O-P-0 OH OH NH o--o CH, OH CH2OH CH,OH OH OH HO UDP-glucose binding makes it easier for the enzyme to unfold. The enzyme likely had phosphate groups added through covalent modification. O Interactions with the bound UDP-glucose stabilize the tertiary structure of glycogen synthase. The UDP-Glucose is a positíve effector which increases the enzyme activity.arrow_forwardBased on the following information for phosphoglucoisomerase, calculate the equilbrium constant and round to the nearest tenths place. R = 8.3145 J/mol⋅K ΔG∘’ = -14.2 kJ/molarrow_forwardEnzymes are specific to their substrates. How is this important?arrow_forward
- 32. Although most enzymes are quite specific, they can catalyze side reactions with compounds that are structurally similar to their physiological substrates, but usually at much slower rates. For example, glyceraldehyde-3-phosphate dehydrogenase (GAPDH), which normally catalyzes the oxidative phosphorylation of glyceraldehyde-3-phosphate, can slowly convert erythrose-4-phosphate, an intermediate in the pentose phosphate pathway, to 1,4-bisphosphoerythronate: H OPO² H-C-OH H-C-OH +NAD HLC-OPO. Erythrose-4- phosphate GAPDH H-C-CH H-CHOH +NADH + H² H.C-OPO. 1,4-Bisphosphoerythronatearrow_forwardWhy do we say the two enzyme-catalyzed reactions taking place in your test tube are "coupled"? O peroxidase and glucose oxidase utilize hydrogen peroxide as a substrate O peroxidase utilizes the lactone produced by glucose oxidase as a substrate O because there is a dye in solution O peroxidase and glucose oxidase utilize glucose as a substrate Operoxidase utilizes the hydrogen peroxide produced by glucose oxidase as a substrate Evaluatearrow_forwardChemistry What is the main aspect that the enzymes succinyl-CoA synthetase, pyruvate kinase, and phosphoglycerate kinase have in common?arrow_forward
