Solution

answer: 1)INORGANIC MOLECULES:Molecules that are not found in living organisms are called inorganic molecules.

example:diamond

2)ORGANIC MOLECULES:Molecules found in all living organisms are called organic molecules.

example:oxygen

3)FOUR MOLECULES OF LIFE:Proteins,lipids,carbohydrates,nucleicacids.

4)TRIGLYCERIDE:Triglyceride is a lipid molecule made up of one unit of glycerol and three fatty acids.

5)PHOSPHOLIPID:A Phospholipid is made up of two fattyacids which are attached to a glycerol head.

6)BUILDING BLOCKS OF A PROTEIN:Aminoacids are the building blocks of proteins.

7)TYPES OF BUILDING BLOCKS OF PROTEINS:20 types

8)TYPE OF BONDS BETWEEN THE BUILDING BLOCKS OF PROTEINS:Peptide bonds.

9)FUNCTION OF TRIGLYCERIDES:Formation of a lipid bilayer,serves as energy source.

10)FUNCTION OF PHOSPHOLIPIDS:Forming phospho lipid bilayer of plasma membrane.

11) 2 FUNCTIONS OF STEROIDS:Help in body building and reduce inflammation.

12)FUNCTION OF DNA:Inheritance,code for proteins.

13)MOST IMPORTANT PROPERTY OF A PROTEINS FUNCTION:When exposed to extreme conditions,proteins begin to unfold-denature.

14)DIFFERENCES BETWEEN DNA RNA:

DNA:1) It is a double stranded molecule.2)it occurs inside nucleus and some cell organelles.3)sugar is deoxyribose

RNA:1) It is a single stranded molecule.2)it occurs very little in nucleus and most of it is present in cytoplasm.3)sugar is ribose.

15)RNA:Ribonucleic acid.DNA:Deoxyribonucleic acid.

16)COMMON ENERGY MOLECULES OF LIFE:proteins, lipids,carbohydrates, nucleicacids.
