Question

2-BPG causes hemoglobin to remain in the state and overall the blood is able to bind oygen a) R, more b) T, more c) R, less d) T, less 10. Which of the statements below correctly describes what an enzyme does? a) An enzyme decreases the value of Gnn- b) An enzyme increase the activation energy c) An enzyme decreases the value of G of the transition state. d) An enzyme decreases the value of Keq 11. Shape complementary is seen in chymotrypsin as the active site is , only fitting amino acids. a) small, small b) large, large c) negatively charged, positively charged d) hydrophobic, hydrophobic 12. If an enzyme-catalyzed reaction has a high rate at low pH and low rate at higher pH, this implies that a group on either the enzyme or the substrate must be for an efficient reaction. a) protonated b) deprotonated c) acidic d) basic 13. The KM can be considered to be the same as the dissociation constant KD for E + S ES if: a) This statement cannot be completed because KM can never approximate KD b) ES E + P is slow compared to ES E+S. d) keal/KM is near the diffusion-controlled limit 14. Which of the following is NOT a way metal ions are able to catalyze a reaction? a) Metal ions can neutralize unfavorable charges in the transition state. b) Metal ions can position substrates correctly for the reaction to occur. c) Metal ions d) All of these are ways metal ions can catalyze a reaction. can participate in oxidation and reduction reactions. 15. Which of the following about the symmetry and sequential models of allosterism is true? a) In both all complexes have subunits that are all in the T state or all in the R state. b) In the symmetry c) In both models it is possible to have a protein with four oxygens in the T state. model both the T and R states have the same affinity for oxygen. In the sequential model binding of one oxygen in one subunit causes a change in neighboring subunits, making oxygen binding easier in those subunits.

Explanation / Answer

Answer 1)

2,3-BPG binds to deoxyhemoglobin, it acts to stabilize the low oxygen affinity state (T state) of the oxygen carrier &

making it harder for oxygen to bind haemoglobin and more likely to be released to adjacent tissues It means blood is able to bind less oxygen.

So complete statement is,

2,3-BPG cause Hb to remain in T state and overall the blood is able to bind less oxygen.

Answer option : (d)
