Answer:c. Steroids/cholesterols and phospholipids
Explanation:
The cell membrane structure exhibit a fluid mosaic model due to the presence of two types of membrane lipids these are phospholipids and sterols like steroids/cholesterols.
A phospholipid is a kind of lipid that is made up of glycerol, two fatty acids in tail and a head group associated with the head group. The biological membrane forms two layers of phospholipids with their tails that points inwards and the arrangement is called as the phospholipid bilayer.
The cholesterol is the another membrane lipid in the cell membrane. It is composed of fused carbon rings present along the side of phospholipids.

Okay so, </span><span>All living organisms respire in order to release energy from glucose. The energy released is stored as chemical energy in the form of a molecule called ATP. This molecule contains high energy bonds which, when broken down, release energy that is available for metabolic reactions within the cell. The waste products of respiration are carbon dioxide and water. Carbon dioxide is released to the air. :)</span>
