- How can we tell whether a reversible inhibitor inhibits in a competitive, noncompetitive, or noncompetitive manner?arrow_forwardHow does competitive inhibition differ from non-competitive inhibition?arrow_forwardUsing equilibrium argument, why does Km apparently increase, decrease or stay the same in uncompetitive inhibition?arrow_forward
- In my text book, three types of inhibitions: 1, competitive inhibition 2. non-competitive inhibition 3. uncompetitive inhibition Reversible competitive inhibition is not listed on my text book although I understand your reasponing in your context. In my understanding, when we draw LB, it is always draw reversible line. If LB is not required, can I say this is competitive inhibition? what are the tips to memorize these three types of inhibition?arrow_forwardIn pure noncompetitive inhibition: a. Where on the enzyme does the inhibitor bind? b. Does the inhibitor bind to E, ES or both? c. What is the effect of I on Vmax? d. What is the effect of I on Km?arrow_forwardCan enzyme inhibition be reversed in all cases?arrow_forward
- What is the advantage of using ATP as a common energy source?Another way of asking this question is, “Why does ATP provide anadvantage over using a bunch of different food molecules?” For example,instead of just having a Na+/K+-ATPase in a cell, why not have manydifferent ion pumps, each driven by a different food molecule, like aNa+/K+-glucosase (a pump that uses glucose), a Na+/K+-sucrase (a pumpthat uses sucrose), a Na+/K+-fatty acidase (a pump that uses fatty acids),and so on?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_forwardCompare and contrast the actions of an allosteric effector, a competitive enzyme inhibitor, and a noncompetitive inhibitor.arrow_forward
- What is contact inhibition?arrow_forwardHow can competitive and pure noncompetitive inhibition be distinguished in terms of KM?arrow_forwardI don't know if I'm correct, but does glucose acts as competitive inhibitor here (Vmax is unchanged, Km increased)? Also, just to be sure, is that what they are asking for in the question? Thank you.arrow_forward
