smooth endoplasmic reticulum

3.state the biomolecular composition and function of the following cell components:

plasma membrane , rough endoplasmic reticulum, cell wall,mitochondria,chloroplast.


4.state why oils form plant sources remain liquid at 25 % c, but that of animal source is solid at the same temperature

1)

importance of biochemistry in agricultural science

Adulteration

Prevent disease

Biochemical tests

Biochemical study

Good output on field


2)mitochondria, lysosomes, Golgi apparatus

endoplasmic reticulum, Golgi apparatus, chloroplasts, these found in eukaryotes


3)plasma mebrane - Helps in separation of inner and external environment of the cell.It is a selectively permeable membrane and only allows selected material to come inside the cell.

Chromosome- They contain genes which helps in transfer of character of inheritance from parents to the child.

Ribosome - Help in synthesis of proteins. Found in Rough endoplasmic reticulum.

Nucleus - Brain of the cell and controls everything happening in the cell.

Mitochondria- Known as the power house of the cell helps in production of energy.

Chloroplast- converts light energy into relatively stable energy.


4)As ee know that both fats and oils are molecules shaped like a capital E with a glycerol spine and arms made of fatty acid chains , this is the reason oils form plant sources remain liquid at 25 % c, but that of animal source is solid at the same temperature.


5)glycolipids

cholesterol

6)

"\npH=pK a +log{[Salt]\\over [Acid]}\n\u200b\t\n "


"\npH=pK a +log{[Salt]\\over [Acid]}\n\u200b\t\n \\\\2 = 8.95 +log{[A^-]\\over[HA]}"


Rato = "10^{-6.95}:1"
