Question

Question 2 (b) The membranes of both B cells and the cancer cells are largely composed of phospholipids. Explain how, when the membranes are fused, the polar parts of the phospholipids from one cell will interact with the phospholipids from the other cell and how the nonpolar parts of the phospholipids from one cell will interact with the phospholipids from the other cell.

Honestly i need help in this my self but i hope that this model can help!

Answer 2

The major component of cell membranes are lipids. They have two groups attached to them which are called “hydrophobic fatty acid tails” and “hydrophilic head”. B cells are called lymphocytic cells which provide immunity by secreting antibodies. Cancer cells are cells which continuously repeats itself to form a tumor structure.

When the polar parts interact hydrophobic tails are lined up with one and another. They form a membrane which diffuses creating a membrane of hydrophilic head on two sides facing water .Thus a brief explanation of how polar and the nonpolar parts combine are explained.
