Which is the effector in the example of blood glucose regulation? A) Blood glucose concentration B) Glucagon C) The liver D) The pancreas
Answer (1)
In the context of blood glucose regulation, the effector is the component that carries out the response to return a system to its set point. When blood glucose levels deviate, the body needs to bring these levels back to normal.
The process of blood glucose regulation involves several key components:
Sensor: The pancreas detects changes in blood glucose levels.
Control Center: The pancreas acts as the control center, releasing hormones (insulin and glucagon) in response to changes in blood glucose levels.
Effectors: These are the organs or tissues that carry out the necessary response to correct the imbalance. In this scenario, the liver acts as the primary effector.
The Liver (Option C): When blood glucose levels are low, the pancreas releases glucagon. The liver responds to glucagon by converting stored glycogen into glucose, releasing it into the bloodstream to increase blood glucose levels. Conversely, when blood glucose is high, the pancreas releases insulin, signaling the liver to convert glucose into glycogen for storage.
Thus, the effector in the example of blood glucose regulation is the liver, making the correct answer:
C) The liver
This explanation should help you understand the roles each component plays in maintaining blood glucose homeostasis within the body.
