Answer:
Polysaccharide
Explanation:
Carbohydrates are one of the of the four biological molecules in living systems. They consists of simple units called monosaccharide, or commonly called simple sugars. The polymers of carbohydrate are made up of thousands of these monosaccharides linked together via a glycosidic bond.
For example, the starch molecule is a carbohydrate polymer made up of hundreds to thousands of glucose molecules (monosaccharide) linked together. Hence, a long chain carbohydrate made up of series of monosaccharide like starch is called a POLYSACCHARIDE i.e. many saccharides or simple sugar unit
Answer:
Protein is a marcomolecule that contains carbon,hydrogen,oxygen, and nitrogen which is used by the organisms for growth and repair
Explanation:
Macromolecules are those molecules which are large in size and does not pass through semi-permeable of the cell during the process of diffusion and active transport. Protein is a macromolecule which is composed of many amino acid. Our body does not take protein directly, it is first broken down into simpler substances such as amino acids. This amino acid is absorbed by the body and use it for growth and repair of damage cells.
The answer is D. oxygen is smaller then proteins.
