- What is the reciprocal substrate relation in the synthesis of ATP and GTP?arrow_forwardWhy is feedback inhibition important in the metabolic pathways?arrow_forwardHow do non-competitive inhibitors affect KM and Vmax? (explain with details) Feedback inhibition typically impedes the activity of the enzyme that catalyzes the first committed step of a metabolic pathway, rather than an enzyme that catalyzes a later step in the pathway. Why is this adaptive?arrow_forward
- Can enzyme inhibition be reversed in all cases?arrow_forwardWhat is the significance of the fact that regulatory enzymes often are located at pathway branch points? What are isoenzymes, and why are they important in pathway regulation?arrow_forwardThere are several types of enzyme regulators which can either be positive ("turn on") or negative ("turn off") regulators. Why would you ever want to "turn off" an enzyme?arrow_forward
- Is the inhibitor competitive uncompetitive or non competitive? Why?arrow_forwardHow can you decrease (or stop) the rate of binding for a noncompetitive inhibitor? Could you change the receptor allosteric sites to prevent noncompetitive binding?arrow_forwardWhat do you mean by feedback inhibition or end-product inhibition ?arrow_forward
