a.
To determine:
In which direction( into the cell or out of the cell) would the Na+ be transported if the transport protein in the cell membrane was: an ATPase pump.
Concept introduction:
ATPase pump: it is an enzyme found in the plasma membrane of animals cells. It performs many functions in the cell physiology like it pumps solutes.
b.
To determine:
In which direction( into the cell or out of the cell) would the Na+ be transported if the transport protein in the cell membrane was an ion transport operating under facilitated transport.
Concept introduction:
Facilitated diffusion: It involves the passive movement of molecules by facilitated transport along their concentration gradient by the presence of another molecules, generally an integral memebrane protein forming a pore or channel.

A stock solution of I2 is standardized using a 0.1430 g sample of pure ascorbic acid. The titration to the starch endpoint required 25.45 mL of the I2 solution. Calculate the molarity of the I2 solution. 2. A vitamin C tablet was divided into three equal mass portions. One portion was crushed into a fine powder, dissolved in water, and titrated with the standardized solution from question 2 (above). The titration to the endpoint required 27.60 mL of the I2 solution. Calculate the number of milligrams of vitamin C that are in the original tablet.arrow_forward
