Question

which of the following statements regarding blood types is false? the surface antigens are glycoproteins or glycolipids, whose characteristics are genetically determined. the blood of a type a, type b, or type o individual always contains antibodies that will attack foreign surface antigens. a typical white blood cell plasmalemma contains a number of surface antigens, or agglutinogens, exposed to the plasma. an individuals blood type is determined by the presence or absence of specific components in erythrocyte cell membranes.

Explanation:

• Blood type is determined by erythrocyte (red blood cell) surface antigens, not white blood cells. White blood cells have different functions like immune response.
• Surface antigens (agglutinogens) on erythrocytes are glycoproteins or glycolipids and genetically determined.
• Blood of type A has anti - B antibodies, type B has anti - A antibodies, type O has both anti - A and anti - B antibodies (attack foreign antigens).
• Blood type is based on erythrocyte membrane components (presence/absence of specific antigens).

Answer:

A typical white blood cell plasmalemma contains a number of surface antigens, or agglutinogens, exposed to the plasma.
