Using the fluid mosaic model, a cell is actively capable of protecting itself against injurious agents by:
A)closing down the membrane transport channels to hormones and chemicals.
B)altering the number and patterns of receptors to bacteria, antibodies, and chemicals.
C)increasing the number and sensitivity of lysosomes to destroy bacteria.
D)shifting the bilayer from hydrophobic to hydrophilic in response to antibodies.

Question

Quizplus · Accepted Answer

Hormones, bacteria, viruses, drugs, antibodies, chemicals that transmit nerve impulses (neurotransmitters), and other substances attach to the plasma membrane by means of receptor molecules on its outer layer. The number of receptors present may vary at different times, and the cell is capable of modulating the effects of injurious agents by altering receptor number and pattern. This aspect of the fluid mosaic model has drastically modified previously held concepts concerning the onset of disease.
