Question

Which statement about enzyme catalysis is false? All of the active site amino acids are next to each other in the primary sequence. Enzymes speed up reactions by forming specific non-covalent bonds between the enzyme amino acids and the transition state molecule. Some enzymes require other molecules, called cofactors, to carry out chemical reactions. Generally, the most important amino acids for an enzyme's function are those in the active site. Question 6 1 pt When [S] is much more than KM: (Choose all answers that are correct.) all of the enzyme is bound to substrate. the enzyme is operating at Vmax- most of the enzyme is not bound to substrate. the reaction is occurring slowly. half of the enzyme is bound to substrate. the enzyme is working at half of its fastest speed.

Answer 1

5)All the active site amino acid are next to each other in primary sequence is the false statement. because protein is globular molecule any amino acid might be active site residue it is not essential to remain next to each other.

6) All the enzyme is bound to substrate and the enzyme is operating at Vmax.

Km michelles menten constant is the measure of affinity of substrate for enzyme at which Vmax is half.

if Km is lower,binding of substrate is good towards enzyme.
