When blood glucose levels are high View Available Hint(s) When blood glucose levels are high The pancreas releases insulin. The pancreas releases glucose. The liver releases insulin. The pancreas releases glucagon. The liver releases glucagon.

Explanation:

Pancreas release both insulin as well as glucagon, but there release depends on different glucose levels in bloodstream. When blood glucose concentration increases, in response to it Insulin is released by the beta cells in the islets of Langerhans.

Role of insulin: i) it lower glucose levels in the bloodstream, ii) it also promote the storage of glucose in muscle, liver and other parts o the body .

While  alpha cells in the islets of Langerhans produce glucagon when glucose concentration decreases in the blood.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
