Question

Question 6 Extracellular chlo pride ion (CI) concentrations are much higher than intracellular. This gradient is maintained in part by co-transport of K't and Il using indirect active transport. Maintenance of the CI concentration gradient using this mechanism is therefore dependent on: Cat + channels The Nat /K+ ATPase Facilitated diffusiorn high extracellular glucose 0, Question 7 The hormone glucagon is secreted by the pancreas in response to low blood sugar, Liver cells respond to glucagon by breaking down glycogen to form glucose, which is then release into the bloostream for the other tissues. Based on this information, what type of transport is most likely responsible for getting the glucose back out into the bloodstream? Direct active transport Indirect active transport Facilitated diffusion Simple diffusion

Explanation / Answer

Answer 6: The correct answer is : The Na+ /K+ ATPase .

This movement of sodium ans potassium ions are interdependent on each other. Foe every three molecules of sodium , two possium ions move out of the cell and thus ionic balance is maintained inside and outside of the cell.

Answer 7: The correct answer is: Facilitated diffusion.

Glucose cannot diffuse directly thruough the membrane. GLUT transporter facilitates transport of glucose across the cell membrane.
