Verified step by step guidance1
Understand the role of glucagon: Glucagon is a hormone produced by the alpha cells of the pancreas. Its primary function is to increase blood glucose levels.
Identify the mechanism of action: Glucagon promotes the conversion of stored glycogen in the liver into glucose, which is then released into the bloodstream.
Consider the physiological context: Glucagon is typically released when blood glucose levels are low, such as between meals or during fasting, to ensure a steady supply of glucose to the body.
Evaluate the options: Given glucagon's role in increasing blood glucose levels, determine which option aligns with this function.
Conclude the effect: Based on the understanding of glucagon's function, select the option that states glucagon increases blood glucose levels.
