Ascrosome reaction is sperm is triggered by

Options

A. capacitation
B. release of lysin
C. influx of Nat
D. release of fertilizin

Answer

C

Explanation

The activated spermatozen on reaching the egg plasma membrane, undergoes a number of changes in its acrosomal region. All these changes are collectively described under acrsome reaction A crosome reaction is calcium - dependent involving massive uptake of calcium and sodium with an efflux of hydrogen generating high pH and osmotic pressure, producing negative surface charge , and partial or total release o the acrosomal enzymes. calcium influex may activate phospholipase resulting in accumulation of unsaturated fatty acids and fusiogenic lysophospholipids contributing to acrosome reaction .
