When calcium concentration increases during depolarization, it shifts the conformation of troponin and tropomyosin, and actin is able to associate with myosin. As calcium is taken up again by the sarcoplasmic reticulum the muscle cell relaxes.

Insulin and Glucagon are produced in the:______.
ElenaW [278]

Answer:

Pancreas; islet of langerhans

Explanation:

Insulin and Glucagon are both hormones released into the bloodstream with the function of regulating blood sugar level. Insulin is released when the blood sugar level (glucose) is high, hence, it converts excess glucose to glycogen, which is stored in muscles. Insulin also helps the cell to utilize glucose as an energy source. Glucagon, on the other hand, functions to convert stored glycogen to glucose (glycogenolysis) when the glucose levels in the blood is low.

Both hormones i.e. Insulin and Glucagon are secreted into the bloodstream by an endocrine gland called PANCREAS, which is a digestive organ found near the stomach. Specifically, the pancreas contains regions that contain endocrine cells called ISLET CELLS. This region, called Islet of Langerhans, is where the hormones are produced in the PANCREAS.
