An extreme change in pH from optimum would affect enzyme activity by: denaturing

Question

An extreme change in pH from optimum would affect enzyme activity by: denaturing the enzyme decreasing the energy of the enzyme breaking peptide bonds increasing the rate of the reaction What type of inhibition is occurring when the inhibitor may bind to either the enzyme or the enzyme-substrate complex? irreversible uncompetitive competitive noncompetitive The value for Km is equal to: Vmax [Substrate] at Vmax [Substrate] at 1/2 Vmax 1/2 Vmax The restriction enzymes used in lab broke bonds between what compounds? amino acids proteins carbohydrates nucleic acids DNA migrates toward the positive (red. electrode on the gel due to the highly net ___ charge on the DNA resulting from the ___ within the DNA structure. positive, phosphates positive, bases negative, phosphates negative, bases

Explanation / Answer

Q51

changes in pH will break peptide bonds (hydrogen bonding)

Q52

uncompetitive, since this is not directly competitive, yet not irreversible

Q53

Km = 1/2 V max always, according to michelis menten kinetics

Q54

The bonds are broken between nucleic acids (which are peptides)

Q55

possitive --> BASES
