Question 6 of 27

1

The change in blood glucose concentration can be detected by organ A. If it releases hormone B into the blood, hormone B will convert glucose to glycogen and the concentration of glucose in the blood will decrease. If it releases hormone C into the blood, hormone C will stimulate organ D to convert glycogen to glucose and the blood glucose concentration will increase.

NAME ORGAN A AND HORMONES B AND C

Select one or more of the following:

Organ A - PANCREAS
Hormone B - GLYCOGEN
Hormone C - INSULIN
Organ A - PANCREAS
Hormone B - INSULIN
Hormone C - GLYCOGEN
Organ A - LIVER
Hormone B - GLYCOGEN
Hormone C - INSULIN
Organ A - LIVER
Hormone B - INSULIN
Hormone C - GLYCOGEN

Explanation

Question 7 of 27

2

Why is glucose converted to glycogen rather than just kept as glucose in the cells

Select one or more of the following:

glycogen takes up less space and can therefore be stored more easily
glycogen is easier to digest and can therefore speed up digestion
glycogen is insoluble and is therefore not in danger of osmosis
glucose is bad for the human body and must therefore always be converted into glycogen
