[amp_mcq option1=”Protein” option2=”Lipid” option3=”Carbohydrate” option4=”Both (a) and (b)” correct=”option4″]<\/p>\n
The correct answer is (d).<\/p>\n
The plasma membrane is a thin, flexible barrier that surrounds all cells. It is made up of a phospholipid bilayer, which is a double layer of phospholipid molecules. Phospholipids are molecules that have a hydrophilic (water-loving) head and a hydrophobic (water-fearing) tail. The hydrophilic heads of the phospholipids face the inside and outside of the cell, while the hydrophobic tails face each other in the middle of the membrane.<\/p>\n
The plasma membrane is also studded with proteins. These proteins serve a variety of functions, such as transporting molecules across the membrane, sensing changes in the environment, and attaching the cell to other cells.<\/p>\n
Carbohydrates are not a major component of the plasma membrane, but they can be found attached to proteins and lipids. These carbohydrates help the cell to recognize other cells and to attach to surfaces.<\/p>\n
In conclusion, the plasma membrane is made up of both proteins and lipids. These two components work together to form a barrier that protects the cell and allows it to communicate with its environment.<\/p>\n","protected":false},"excerpt":{"rendered":"
