Question
The [ Select ] ["innate immune system", "antibody", "macrophage", "complement"] proteins can puncture a cell membrane by forming a large [ Select ] ["lipophilic complex", "multi-protein ATPase", "pore"] , but this only happens when directed by binding of [ Select ] ["complement", "antibodies", "neutrophils"]
Hemoglobin [ Select ] ["H", "G", "F", "A"] cannot bind [ Select ] ["IP3", "PI3,5P2", "2,3-DPG"] and has a [ Select ] ["lower", "reduced", "higher"] affinity for O2.
In the kidney, [ Select ] ["manganese", "potassium", "chloride", "sodium"] ions are largely reabsorbed in the [ Select ] ["glomerulii", "descending loops", "proximal tubule"] but in the presence of aldosterone these ions are secreted in the [ Select ] ["collecting duct", "Loops of Henle", "ascending tubule"]
Explanation / Answer
The complement protiens can puncture the cell membrane by forming a large pore, but this only happens when directed by formation of antibody.
Haemoglobin F cannot bind to 2,3 DPG and has a higher affinity for oxygen. In kidney potassium ions are reabsorbed in Proximal tubule. But in presence of aldosterone these ions are secreted in collecting duct.
Complement system is a part of immunoty system of body. It enhances effect of antibody and phagocytosising cells. It attacks cell membrane of pathogen.
In foetal life, Hb F is present. This Hb is not sensative to 2,3 BPG. 2,3BPG is known to decrease affinity of Hb towards oxygen. Thus, foetal Hb is more sensative to oxygen.
Aldosterone causes reabsorption of sodium and secretion of potassium. Aldosterone is the salt water balancing hormone of body. It is released in response of lower blood pressure by adrenal gland.
