Feedback inhibition is a common means of biochemical regulation
Homework Answers
18. In feedback inhibition, the allosteric enzymes always catalyze the committed step of a metabolic pathway.
In metabolic pathways which are regulated by feedback inhibition , the first step is the committed step which determines the rate of the entire pathway. It is regulated by the end product of the pathway, i.e. the entire pathway is operated when there is a need for the synthesis of the end product. If the end product is available the pathway is slowed down or stops completely. The first committed step is regulated by the product itself.
19. All the above - option is correct.
20. Alpha helix is the correct one as it is formed due to H-bonding between 1st and 5th amino acid.
21. The correct option is - The pI of the biomarker is lower than protein A and its molecular weight is higher. Biomarker spot is observed towards lower pH range to that of protein A. It is observed below the biomarker hence biomarker's mole wt is higher than protein A.
22. Induced fit is the correct one.
23. Histidine
24. Lysine
