Question

Use the following graph to answer the questions.

a) Describe what happened to the person's blood glucose concentration at 5 h.

b) Identify the hormone that was released at 7 h, the gland that released it, and the stimulus.

c) Identify the hormone that was released at 8 h, the gland that released it, and the stimulus.

d) Predict how the graph would look if the person engaged in strenuous exercise in 12 h. What hormone would be released during exercise?

e) Suppose the person has type 1 diabetes. When would they have taken insulin

Explanation / Answer

a) the person has taken food at 5 hours. therefore, glucose concentration started to increase after 5 hours. however, at 5 hours, the glucose concentration has no change.

b) the hormone that was released at 7 hours: insulin

the gland that released: pancreas

stimulus: increased blood glucose level.

c) the hormone that was released just after 8 hours: glucagon

the gland that released it: pancreas

stimulus: decreased blood glucose level.

d) when the person is engaged in a strenuous exercise in 12 h, the blood glucose would be metabolized so that the blood glucose level drops. this acts as a stimulus for the secretion and release of glucagon from pancreas gland.

e) type 1 diabetics are not able to produce insulin. therefore, they have to take insulin 15 to 30 min before taking food. therefore, the person in the graph would have taken insulin at 4.5 hours.
