Question

The hormone insulin regulates glucose concentration in the blood through metabolic changes. Complete the flowchart below by moving the labels to the correct targets. Note that one of the targets should have three answers. Not all the labels will be used.

Flowchart:
Blood ----> Increased Glucose Concentration ------> (Fill in Blank) ------> Insulin Released -----> Muscle and Other Tissues (three metabolic effects) ------> (Fillin blank with 3 of the choices) -------> Adipocytes ------> (Fillin Blank)

Choices:

1. Increased glucose uptake
2. increased glycogen synthesis
3. decreased glucose uptake
4. pancreatic alpha cells
5. increased triacylglycerol synthesis
6. decreased glycogen breakdown
7. pancreatic beta cells
8. increased glycogen breakdown

Answer 1

Blood ----> Increased Glucose Concentration ------> (pancreatic beta cells) ------> Insulin Released -----> Muscle and Other Tissues ----> (Increased glucose uptake) -------> (increased glycogen synthesis------ decreased glycogen breakdown) ------ -------> Adipocytes ------> (increased triacylglycerol synthesis )

Step-by-step explanation:

Insulin is produced by the pancreas and acts to control blood glucose. When we consume food, it is necessary for glucose to be absorbed by the cells, the glucose molecules that are not absorbed have become loose in the bloodstream, if the amount of insulin in the blood is not at the correct levels, the glucose will accumulate causing problems.

We can summarize how insulin acts in the body with the following flowchart:

Blood ----> Increased Glucose Concentration ------> (pancreatic beta cells) ------> Insulin Released -----> Muscle and Other Tissues ----> (Increased glucose uptake) -------> (increased glycogen synthesis------ decreased glycogen breakdown) ------ -------> Adipocytes ------> (increased triacylglycerol synthesis )

Answer 2

Blood ----> Increased Glucose Concentration ------> pancreatic beta cells------> Insulin Released -----> Muscle and Other Tissues ---- Increased glucose uptake------- increased glycogen synthesis------ decreased glycogen breakdown------ -------> Adipocytes ------> increased triacylglycerol synthesis
