Concept explainers
(a)
Interpretation:
The reaction or process that is catalyzed by pepsin enzyme should be determined.
Concept Introduction:
The enzymes are considered as the catalyst for the biochemical reaction. They are involve in the biochemical reactions to speed them up but again regenerate at the end of the reaction or process. The Lock and Key model was purposed to explain the reactivity of enzymes. It states that each enzyme has certain active sites that can only allow the bonding of certain subtract molecules. An enzyme is very specific for the substance, pH, and temperature of the surroundings.
(b)
Interpretation:
The reaction or process that is catalyzed by succinate dehydrogenase enzyme should be determined.

- How much ATP is formed by the complete catabolism of stearic acid, C 18H 36O 2?arrow_forwardTPP is a coenzyme for transketolase, the enzyme that catalyzes the conversion of a ketopentose (xylulose5-phosphate) and an aldopentose (ribose-5-phosphate) to an aldotriose (glyceraldehyde-3-phosphate) and a ketoheptose (sedoheptulose-7-phosphate). Notice that the total number of carbons in the reactants and products is the same (5 + 5 = 3 + 7). Propose a mechanism for this reaction.arrow_forwardDescribe the reactions that you would expect these enzymes to catalyze.(a) Alcohol dehydrogenase (b) Aspartate transaminase(c) Tyrosine-tRNA synthetase (d) Phosphohexose isomerasearrow_forward
- The oxidation of 1 mol of glucose supplies enough meta-bolic energy to form 36 mol of ATP. Oxidation of 1 mol of a typ-ical dietary fat like tristearin (C₅₇H₁₁₆O₆) yields enough energyto form 458 mol of ATP. (a) How many molecules of ATP canform per gram of glucose? (b) Per gram of tristearin?arrow_forwardAnaerobic glycolysis (i.e., lactic acid fermentation) produces pyruvate that is then converted to lactate through the activity of lactate dehydrogenase. The conversion of pyruvate to lactate would seem to be an unnecessary step, since this process does not result in any further release of energy. Explain the necessity for the production of lactate as the endpoint for anaerobic glycolysis.arrow_forwardRefer to the following reaction. The substrate of this reaction is called through a mechanism called "Feed Forward Activation". (A) Phosphoenolpyruvate, Fructose 1,6-bisphosphate Lactate, NADH OPO₂²- ADP ATP J = 4 O H₂C H₂C 2-phosphoglycerate, AMP Glyceraldehyde 3-phosphate, ATP and the enzyme is activated by high conc. ofarrow_forward

How do these two binding events differ in their effects on the enzyme's activity?arrow_forward
- Triose phosphate isomerase catalyzes the conversion of dihydroxyacetone phosphate (DHAP) into glyceraldehyde-3-phosphate (G3P). Which of the following illustrates this chemical reaction? a) A b) B c) C d) Darrow_forwardChemistry What is the main aspect that the enzymes succinyl-CoA synthetase, pyruvate kinase, and phosphoglycerate kinase have in common?arrow_forwardATP is produced during synthesis of compounds.
