Answer #1

Small ions like sodium, potassium, bicarbonate ions, glucose, water can pass through glomerular capilaries.

And haemoglobin in erthyrocytes, roteins which have low permeability cannot pass through glomerular capillaries.

ADH means anti diruetic harmone.

It's function is to maintain the concentration of urine.

When there is more amount of water in the body, it helps in excreation of water and salts.

And when there is low amount of water ,it helps in absorption of salts and water.

2 harmones which regulate sodium absorption and blood volume are-

Aldosterone, anti diruetic harmone

These both harmones regulate blood volume and help in maintaining the concentration of urine.

An ion-channel is a transmembrane protein that can be in one of two states: OPEN (which allows ions to pass through the membrane) and CLOSED (which does not permit ions to pass through). You have an ion-channel in which the energy of the open state is 600 cal mol-1, the energy of the closed state is 1800 cal mol-1, and the temperature of the system is 300 K. (one cal per mole is equal to 4.18 J per mole, or...
