Question

what happens when the plasma concentration of glucose increases? epinephrine (adrenaline) gets released from beta cells in the islets of langerhans of the pancreas. glucagon gets released from beta cells in the islets of langerhans of the pancreas. insulin gets released from beta cells in the islets of langerhans of the pancreas. insulin gets released from alpha cells in the islets of langerhans of the pancreas. question 18 (1 point) what is true about cortisol? it is a hormone that is produced by cells in the zona reticularis of the adrenal cortex that decreases the plasma concentration of glucose. it is a hormone that is produced by cells in the adrenal medulla that increases the plasma concentration of glucose. it is a hormone that is produced by cells in the zona glomerulosa of the adrenal cortex that inhibits na+/ k+ pumps in the kidney. it is a hormone that is produced by cells in the zona fasciculata of the adrenal cortex that increases the plasma concentration of glucose.

Explanation:

When plasma glucose concentration increases, beta - cells in the islets of Langerhans of the pancreas release insulin to lower the glucose level. Cortisol is produced by cells in the zona fasciculata of the adrenal cortex and it increases the plasma concentration of glucose.

Answer:

For the first question: Insulin gets released from beta cells in the islets of Langerhans of the pancreas.
For the second question: It is a hormone that is produced by cells in the zona fasciculata of the adrenal cortex that increases the plasma concentration of glucose.
