Trypsin is secreted as zymogen from the pancreas, which is called trypsinogen. Trypsinogen is the inactive form and is activated by enterokinase... View Article
Trypsin was discovered by Wilhelm Kühne. He observed that it is secreted as an inactive proenzyme (trypsinogen) from the pancreas. Trypsin... View Article
The increased partial pressure of CO2 (pCO2) favours the dissociation of oxyhaemoglobin. This is the reason for the release of oxygen in tissues.... View Article
The oxyhemoglobin dissociation curve relates the percentage saturation of haemoglobin with the partial pressure of oxygen (pO2). It tells about... View Article
When carbon monoxide binds to haemoglobin, carboxyhemoglobin is formed. Carbon monoxide has 200 times more affinity than oxygen for haemoglobin.... View Article
Oxygen is dissociated from oxyhaemoglobin in tissues, where pCO2 is high and pO2 is low. Also Check: Do Lungs Have Positive or Negative... View Article
Haemoglobin binds to oxygen in the alveoli, where pO2 is high and pCO2 is low. Haemoglobin bound to oxygen is called oxyhaemoglobin. 97% of... View Article
The oxygen dissociation curve is obtained by plotting the percentage saturation of haemoglobin with oxygen against the partial pressure of... View Article
Ovaries and adrenal glands produce small amounts of androgens such as testosterone in females. Higher than normal levels of androgens are... View Article
The binding of CO (carbon monoxide) to haemoglobin is not irreversible but it has much more (~200 times) affinity to bind with haemoglobin... View Article
Insulin is secreted by beta cells of Islets of Langerhans present in the pancreas. It is involved in glucose homeostasis along with glucagon.... View Article
Somatostatin is also known as growth hormone-inhibiting hormone as it inhibits the release of growth hormone from the pituitary gland. It is... View Article
Pepsin is a proteolytic enzyme secreted by the chief cells of gastric glands as a proenzyme pepsinogen. It is activated by gastric HCl. The... View Article
The carboniferous period of coal deposition was 200 to 300 million years ago. Carboniferous Period is the fifth interval of the Paleozoic Era. It... View Article
The term abiogenesis refers to spontaneous generation. It also refers to the origin of life from non-living substances. The theory of abiogenesis... View Article
