Cellulose makes the cell walls of all plant cells.
Option B
<h3><u>Explanation:</u></h3>
Enzymes are biomolecules that act as biocatalysts and to enhance the rate of a chemical reaction. Lipids and proteins make up the cell membrane bilayer. Cholesterol is a lipid molecule that comes under the category of very low density lipoprotein. Its not associated with storing the genetic information. The DNA stores the genetic information.
Glucose is the chief respiratory substrate of a cell. Its not associated with the increase in rate of a reaction. But cellulose is the molecule that is a polymer of glucose that is associated with the formation of cell walls in plants.
Answer
Macromolecules in human body
The macromolecules found in human body are:
1. Carbohydrate,
2. Proteins
3. Lipids, and
4. Nucleic acids.
Elements they common share
All these macromolecules have three elements in common which are:
1. Carbon
2. Hydrogen, and
3. Oxygen.
These elements constitute about 95% of human body.
Difference in Chemical properties
Carbohydrate is composed of glucose monomers, which may have aldehyde functional group or ketone functional group. Protein is composed of monomers called amino acids. Each amino acid has carboxylic functional group, amino group, alkyl or aryl group and hydrogen atom. Lipid is composed of fatty acids and glycerol. While nucleic acid is composed of monomer called nucleotide. Each nucleotide is composed of pentose sugar, phosphate group and nitrogenous group. Due to the presence of different functional groups all these macromolecules have chemical properties different from each one
Water molecules are polar. This means that one end of the molecule is positively charged, while the other is negatively charged. Opposite charges attract. Water molecules on the faucet that are eventually pulled away from the others by gravity will themselves pull together and form round drops because the charged portions of molecule attract the oppositely charged portions of another.
