Myoglobin is a muscle hemoglobin which exhibits Hyperbolic oxygen dissociation curve indicating its great affinity towards Oxygen ( Non cooperative binding ). The Hyperbolic nature of the curve is due to
Single polypeptide ( 153 amino acids ) and Monomeric nature
High concentration in the muscle
Muscle protein
Quarternary structure

Silicosis
Asphyxia
Emphysema
Embolism
Advantage of Double Bohr effect is
Reciprocal exchange of Oxygen for Carbon dioxide
More Oxygenation of Foetal blood
More removal of Carbon dioxide
All these
Tachypnoea means
Rapid shallow breathing
Rapid deep breathing
Slow and shallow breathing
Slow and deep breathing

All these
Lungs
Skin and Meninges
Intestine
Opercular gills are found in
Both a and b
Lepidosteus

Anabas
Dead air is not involved in respiration because
It is present deep in the lungs
It is very low quantity
It is trapped in nasal passage
It contains less Oxygen
2,3 DPG causes shifting of Oxygen dissociation curve in Adult Hb to Right because
It lacks Hb binding sites
It increases Oxygen affinity for Hemoglobin
It binds to Beta chain of Hb
Its concentration is high in adults
Mammalian RBC respire anaerobically because
It has bicarbonate ions inside
It has stroma inside
It has Haemoglobin
It lacks Mitochondria
During transportation of Carbon dioxide, blood will not become acidic, because
It contains high
It contains hemoglobin
It contains Hemoglobinc acid
It contains Buffers
Foetal hemoglobin has great affinity than adult hemoglobin because
Its polypetide chains bind very fast with Oxygen
It binds 2,3 DPG less avidity by Gamma polypeptide chain than HbA
Its concentration is very high
Foetal blood gets oxygen from the mother
Pinnaglobin is a brown coloured blood pigment present in the plasma of the mollusk Pinn. It contains
Vanadium
Iron
Copper
Manganese
