Functions of enzymes in acrosomal cap?
helps in the penetration of the spermatozoon into the ovum during fertiliztaion.
What is the function of zinc in the active site of the enzyme carboxypeptidase?
cofactor necessary for enzyme activity
What can change the way an enzyme acts?
Enzyme activity is affected by other molecules, temperature, chemical environment (e.g., pH), and the concentration of substrate and enzyme. Activators are molecules that encourage enzyme activity, and inhibitors are enzymes that decrease enzyme activity. Sometimes a cofactor is necessary for the enzyme to work.
What is ovum and what is egg?
An ovum is an egg
How is CTCL determined?
Skin biopsies showing penetration of abnormal cells into the epidermal tissue are necessary to make a firm diagnosis of CTCL.
Functions of enzymes in acrosomal cap?
helps in the penetration of the spermatozoon into the ovum during fertiliztaion.
How does ovum prevent multiple penetrations of sperm cells along its periphery?
as soon as a single sperm fertilises the ovum a change of composition takes place in ovum's outer layer forming zona pellucida which prevents the penetration of other sperms.
