According to sequential model of enzyme substrate binding , when substrate binds to enzyme it changes conformation of enzyme.
Thus change in conformation of enzyme increases the binding affinity for substrate.
Hence 1st option is correct.
Question 27 Which of the following is an assumption of the sequential model? O Substrate binding...
56. In the lock and key model of substrate binding to enzymes Pprat wnich they work best a the substrate changes its conformation to fit the active site b. the active site changes its conformation to fit the substrate c. the active site is rigid and the substrate must fit exactly d. the substrate binds only to part of the active site In the induced-fit model of substrate binding a. 57. the substrate changes its conformation to fit the active...
For the following questions, multiple answers may apply. 1) Enzyme activity in cells is controlled by which processes: a) covalent modifications b) modulation of expression levels c) feedback inhibition d) binding to allosteric effectors 2) Which of the following statements about the concept of “induced fit” are true (2pts): a) Substrate binding induces either global or local conformational change in the enzyme, which then brings catalytic groups into proper orientation. b) When a substrate binds to an enzyme, the enzyme...
1. Protein kinases phosphorylate target enzymes and as a result enzymes become activated or inactivated. Which of the statements are TRUE? (Multiple answers: You can select more than one option) A. Phosphorylated enzymes behave like competitive inhibitors B The presence of a phosphate acts as a non-competitive inhibitor/activator. No change in Km but significant change in Vmax C. The presence of a phosphate group induces a conformational change that modifies the affinity and catalytic ability of a target enzyme D....
