InsulinBaselineJpn.jpg

(Synthesis, secretion, and concentration in blood of) insulin decreases blood glucose. Insulin has a certain (baseline) amount of synthesis, secretion, blood concentration, and blood glucose-decreasing effect before fasting.


Insulin-fast.jpg

① Subject had fasted. Blood glucose is decreased due to the fasting. Insulin (synthesis, secretion, and concentration in blood) decreases blood glucose. These are in the same direction (red).



グルカゴン・インスリン08.jpg

② Since these are in the same direction (red), negative feedback inhibits (blue) insulin (synthesis, secretion, and concentration in blood). Because of this, the blood glucose-decreasing effect of glucagon weakens, and the decrease in blood glucose (blue downward unfilled arrow) disappears (decreased blood glucose increases to the baseline).


Like, when room temperature is decreased (winter), cooler (function) is decreased, this is also redblue negative feedback.


Challenge Quiz

1.

Blood glucose is increased decreased due to the fasting, insulin (synthesis, secretion, and concentration in blood increases decreases blood glucose. Since these are in the same direction opposite direction , negative feedback inhibits facilitates insulin. Because of this, the initial transition dissapears and the blood glucose increases decreases (towards the baseline).

2.

When blood glucose is decreased, negative feedback facilitates inhibits insulin (synthesis, secretion, and concentration in blood).
