Question

Enzymes that cleave molecules by the addition of water are called hydrolyases oxidoreductases apoenzymes synthases The presence of oxygen bound to the heme of hemoglobin causes a change in tertiary structure of the hemoglobin protein. Consequently, the activity of hemoglobin is regulated. This is an example of: inhibition allosteric control denaturation. catalysis. Which of the following is correct concerning the differences between hemoglobin and myoglobin? Both hemoglobin and myoglobin are tetrameric proteins. Hemoglobin exhibits a hyperbolic O_2 saturation curve, while myoglobin exhibits a sigmoid-shaped curve. Hemoglobin exhibits cooperative binding of O_2, while myoglobin does not Hemoglobin exhibits a higher degree of O_2 saturation at all physiologically relevant partial pressures of O_2 than does myoglobin. The T and the R state of an allosteric protein differ in their activity. T and R stand for: tense, and relaxed torsion, and release tense, and reactive transfer, and release The relationship between Delta G' degree and Delta G is best described as: determined, by the temperature and change in entropy

Answer 1

1 ans Hydrolyases

Explanation : Hydrolyases are the enzymes that catalyze hydrollysis by the addition of water

2 Ans Allosteric control

Allosteric control/Allosteric regulation binding of oxygen molecule to hemoglobin where it induces a confirmational change inthat subunit that interacts

3 Ans D. hemoglobin exhibits the higher degree of o2 saturation at all physiologically relavent partial pressures of o2 than does myoglobin

4 Ans tense and relaxed state
