a)function of PCT and DCT
b) kindey and artificial kindey
c)excretion and secretion
d)primary metabolites and secondary metabolites?
Answers
Answer:
a. The PCT regulates pH of the filtrates by exchanging hydrogen ions in the interstitium for bicarbonate ions in the filtrate. ...Proximal convoluted tubule regulate the pH of the filtrate in the kidneys. Functions ofDCT. It maintains a proper concentration and pH of the urine.
b. It is a device to remove nitrogenous waste. products from the blood through dialysis. 2.it is used in person inwhich both kidneys are damaged. ... No absorption of material takes place in artificial kidney.
c. Excretion is a process in which metabolic waste is eliminated from an organism. In vertebrates this is primarily carried out by the lungs, kidneys and skin. This is in contrast with secretion, where the substance may have specific tasks after leaving the cell.Excretion is an essential process in all forms of life.
d. A primary metabolite is a kind of metabolitethat is directly involved in normal growth, development, and reproduction. ... Conversely, a secondary metabolite is not directly involved in those processes, but usually has an important ecological function (i.e. a relational function).
