10) The correct option is e. a and c are correct.
Glycogen is a multibranched polysaccharide of glucose. It acts as a form of energy storage in humans, animals and other organisms. When sugars are joined together to form glycogen, this process is known as anabolism.
11) The correct option is c. lipids and proteins.
The components of the plasma membrane are lipids (phospholipids and cholesterol) and proteins.
12) The correct option is d. regulate the passage of molecules and ions.
The plasma membrane is selectively permeable membrane. It is permeable to ions and organic molecules and regulates the movement of substances in and out of cells.
13) The correct option is b. lipids.
Lipids are class of organic molecules, which are insoluble in water. They are usually made up of fatty acids.
