Questão 6
Questão
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
Responda
-
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
Questão 7
Questão
Why is glucose converted to glycogen rather than just kept as glucose in the cells
Responda
-
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
