Question

Explain in detail, how the intracellular protein buffer system acts to minimize ph changes.

Answer 1

Answer : The intracellular protein ( made up of Aminoacid having functional group amino and acidic  ) buffer system function by way of the -NH2 and -COOH groups present on the amino acid sections within the intracellular proteins. If free H+ is released into the intracellular compartment, the NH2 or COO- groups react with it to bind it by the following reactions.

H+ + -NH2 → -NH3+

H+ + COO- → -COOH

on the other hand, free OH- is released into the intracellular compartment, the -NH3+ or -COOH groups react with it to bind it by the following reactions.

OH- + -NH3+ → -NH2

OH- + COOH → -COO-

Both of these actions is  responsible for minimising ph .... Thanks dear student
