Answer:
1.)Carbohydrates
2.) Lipids
3.)Proteins
4.)Nucleic acids
Explanation:
1. Carbohydrates
The major carbohydrates found in cell walls are cellulose, hemicellulose and pectin. The cellulose microfibrils are bonded through hemicellulosic tethers to give the cellulose-hemicellulose network, that is found in the pectin matrix.
2. Lipids
Cell membrane are majorly made up of phospholipids, glycolipids, proteins, and cholesterol. The lipid found mostly though our the membrane are the phospholipids.
3. Enzymes/proteins
Enzymes are biological molecules that are protein in nature and accelerate the rate of the chemical reactions that occurs within cells.
4. Nucleic Acid
Nucleic acids aid major activities in the cell by serving as the repository of the genetic materials needed for the transfer of inherited characteristics from parents to offspring and from an individual cell to another cell
