Question # 1

Waht are the types of RNA? Write their functions.

Ans 1: There are three types of RNA.
a. Messenger RNA : Carries the genetic informationn from DNA to the ribosomes during protein synthesis
Ans 2: b. Transfer RNA : Transfers specific amino acids to the ribosomes, ensuring the correct sequence during protein synthesis.
Ans 3: c. Ribosomal RNA: Constitutes the structual and functional components of ribosomes. the cellular machinery for protin synthesis.

Question # 2

Why are lipids insoluble in water.

Ans 1: Lipids are organic compoudns made up of carbon, hydrogen and oxygen They have little or no affinity for water in due to the presenc eof mostly hydrocarbons. That is why they ae insoluble in water but soluble in organic solvents such as alcohol

Question # 3

Difference between Fats and Oils.

Ans 1: Fats:
Fats contain saturated fatty acids and so ar esolid at room temperatur e.g. animal fats.
Ans 2: Oils:
Oils contain unsaturated fatty acids and so ar eliquid at room temperatue e.g. plant oils such as olive oil, corn oil, and coconut oil.

Question # 4

What are differente plant sources of proteins.

Ans 1: Plant seeds are most common source of proteins like beans, lentils, peas, nuts.

Question # 5

Give and example of storage polysaccharide in plants.

Ans 1: Starch is a storage polysaccharide found in plants. It is composed of glucose untis.

Question # 6

Define Gene.

Ans 1: Small iece of huge DNA molecule in the chromosome is called gene.
genes actually store and control the hereditary inforaation . Each chrosomes is made up fo large number of genes.

Question # 7

How primary structure of protein is important.

Ans 1: The primary stucture of a protein is important because it determines the protein's three dimensional shape, which is turn determines its function.

Question # 8

Compare the energy level of carbohydrates, Proteins and lipids.

Ans 1: Proterins:
1) One grams of protein has 4 Kcal of energy
2) Proteins can also be use dfor gaining energy
Ans 2: Lipds:
One gram of lipids provides 9.1 Kcal energy whcih is double than carbohydates or proteins.
Lipids act as energy storage in fat, cells, liver and blood.
Ans 3: Carbohydrates:
4 Kcal per grma of energy is released when glucose is broken down in the cell
Carbohydrages ar emajor souce of useable and stored energy in the cells of livng organisms.

Question # 9

Difference between Glycogen and Starch

Ans 1: Glycogen:
Glycogen is the animal starch mainly stored n liver and muscles.
It is broken down into glucose when energy is needed.
Ans 2: Starch:
Starch is a stogage polysaccharide stored in plants.
It is composed of glucose units.

Question # 10

Structure of DNA and RNA

Ans 1: DNA: DNA is made of deoxyribo nucleotides oxy-ribo nucleotides.
Inthis nucleotide the pentose sugar is deoxyribose while nitrogenous base may be adenine a. thymine (T), cytosine (C) or guanine (G)
Ans 2: Structure of RNA:
RNA is signle stranded its strand consists of ribonucleotides.
A ribonucleotide contins ribose sugar instead of deoxyribose. Ina ribonucleotide, the nitrogenous base may be adenind a. Uracil (U) cytosin (C) or guanine (G)
