45. Which one of the given graph shows the effect of pH on the velocity of a typical enzymatic reaction (V)?
46. How Many of the twenty two amino acids are essential amino acids for children?
(a) 6 (b) 8 (c) 10 (d) 11
Dear student,
45) Answer is c)
The enzymatic activity increases with the increase in pH and an optimum pH is obtained where enzyme activity is maximum. So, the peak obtained in the graph is the optimum pH at which maximum activity is attained. After optimum pH activity further decreases.
46) Answer is c) 10
There are 8 essential amino acids (isoleucine, leucine, valine, lysine, methionine, phenylalanine, threonine, tryptophan) which are required by adults and two more (histidine and arginine) along with the 8 essential amino acids are needed by children.
