Answer 1

	Similarity	Differencs
Enzymes and Proteins	All enzymes are protein (except-ribozyme)	1) Enzymes are specific biocatalyst. Ex. Amylase 2) Proteins are diverse in nature eg. Hemoglobin, Keratin
Saturated and unsaturated fatty acids	Both are fats and unsoluble in water	saturated are solid and single bond Unsaturated are liquid at room temp. and consist of one or more double bonds.
Phospholipid and TAG	Both are fats	Phospholipids are major components of plasma membrane TAG stored as energy reserve in adipose tissue
Molecule and atom	Both are important constituent of matter	Molecule are formed when two or more atom join by bonds atoms are basic unit of matter
Covalent and Ionic bond	Both can form the chemical bonds	Covalent bond formed by sharing electron between atoms Ionic bonds formed by one donates electron and another accept
