Hemoglobin is a conjugated protein with prosthetic group heme. Hb is found in the RBCs and carries oxygen from lungs to the tissues and the reverse process occurs when Hb carries CO2 from tissues to the lungs. The red color […]
The DNA is about 1.74 meters if stretched to its full length. To get DNA into the nucleus, it must have a compact form. The structural flexibility of the DNA allows it to form a compacted structure. Eukaryotes contain about […]
In a cell, electron flow in the ETC is done in a proper sequence from either NADH or FAD to oxygen to form ATP. The 3 complexes of ETC are associated with generation of ATP. All these complexes do not […]
DNA serves as a genetic material for both prokaryotic and eukaryotic cells. In eukaryotes, the DNA is present in the nucleus while in prokaryotic cells, it is present with all other cellular contents. In eukaryotic cells, the DNA is bound […]
RNA is similar to DNA. It is a long unbranched macromolecule which consists of nucleotides joined by phosphodiester bonds. The four bases of RNA include: Purine base: adenine and guanine Pyrimidine base: cytosine and uracil Types of RNA:- cell contains […]
Beside being the structural component of the nucleic acids, several nucleotides participate in various biochemical and physiological functions. Such nucleotides are known as biologically important nucleotides. Adenosine tri-phosphate (ATP) It serves as main source of energy for various metabolic pathways […]
“Haemolytic anemia are the anemia which results in the increased rate of red blood cell destruction.” CLASSIFICATION: – The premature destruction of red blood cell in haemolytic anaemia may occur at either of the following two sites: – Firstly, the […]
“A deficiency of folic acid, more properly pteroyl-monoglutamic acid, results in a megaloblastic anaemia having the same characteristics as those encountered in vitamin B-12 deficiency.” 1.] Women are at high risk of having Folate deficiency anaemia. CAUSES: – Following are […]
