Question

15. Which of the following is NOT true for all three of these transport mechanisms: facilitated diffusion, primary active transport, and secondary active transport? A. The transport mechanism is specific for (a) particular solute(s). B. The transport mechanism requires a protein. C. The transport mechanism has a limit to the total number of molecules that can be transported per unit of time. D. The transport mechanism requires energy. E. Transport can be increased by increasing the number of transport molecules in the plasma membrane. 16. Each of the following is an example of homeostasis EXCEPT one. Identify the exception. A. Increased pressure in the aorta triggers mechanisms to lower blood pressure B. A rise in estrogen during the menstrual cycle results in an increase in the number of C. Increased blood sugar stimulates the release of a hormone from the pancreas that D. A rise in blood calcium levels triggers the release of a hormone that lowers the blood E. A decrease in body temperature induces a neural response that initiates physiological progesterone receptors in the uterus. stimulates the liver to store the sugar. calcium levels. changes to increase body temperature. Section II: Match the disease with the description. Each correct response is worth 1 point. A. Addison's disease B. Cushing's disease C. Graves' disease D. Gigantism 17. hypocortisolism 18. excessive secretion of growth hormone

Explanation / Answer

15,the false statement for all the 3 transport mechanisms is c,t he transport mechanisms have a limit to the total no of molecules that can be transported per unit time.

facilitated diffusion dnt require energy.s tatements a,b,e are true.

Rate of transport depends on concentration gradient mainly.

16,b, estrogen and progesterone dnt play a role in homeostasis

17,Hypocortisolism is Addisons diesease

18,excessive secretion of growth hormone is gigantism
