Question 9

The hormone insulin enhances the transport of glucose (sugar)from the blood into most of the body's cells.Its secretion is controlled by a negative-feedback system between the concentration of glucose in the blood and the insulin-secreting cells.Therefore,which of the following statements is correct?

Accepted Answer

A)  A decrease in blood glucose concentration stimulates insulin secretion, which in turn further lowers the blood glucose concentration. 
B)  An increase in blood glucose concentration stimulates insulin secretion, which in turn lowers the blood glucose concentration. 
C)  A decrease in blood glucose concentration stimulates insulin secretion, which in turn increases the blood glucose concentration. 
D)  An increase in blood glucose concentration stimulates insulin secretion, which further increases the blood glucose concentration. 
A)  A decrease in blood glucose concentration stimulates insulin secretion, which in turn further lowers the blood glucose concentration. 
B)  An increase in blood glucose concentration stimulates insulin secretion, which in turn lowers the blood glucose concentration. 
C)  A decrease in blood glucose concentration stimulates insulin secretion, which in turn increases the blood glucose concentration. 
D)  An increase in blood glucose concentration stimulates insulin secretion, which further increases the blood glucose concentration.

Question 18

Platelets,which have negatively charged cell membranes,adhere to the positively charged surface of a torn blood vessel.As they do so,they release substances that attract more platelets to the damaged area and change the charge on their cell membranes to positive.More platelets adhere to the damaged area.The cycle repeats until the damaged area is sealed.What sort of feedback loop is formed?

Accepted Answer

A)  This is a positive feedback loop because the response reinforces the initial change. 
B)  This is a negative feedback loop because the response opposes the initial stimulus. 
C)  This is a negative feedback loop because having too many platelets in one area blocks blood flow. 
D)  This is a positive feedback loop because the response prevents a person from hemorrhaging to death. 
A)  This is a positive feedback loop because the response reinforces the initial change. 
B)  This is a negative feedback loop because the response opposes the initial stimulus. 
C)  This is a negative feedback loop because having too many platelets in one area blocks blood flow. 
D)  This is a positive feedback loop because the response prevents a person from hemorrhaging to death.
