Question

question 3 sam skipped breakfast and hasnt eaten for several hours. what will the body do to maintain blood sugar levels? muscle cells absorb glucose to increase energy. the brain signals the pancreas to produce glucagon. the pancreas releases insulin to lower blood sugar. the liver stores more glucose to prepare for fasting.

Explanation:

When blood - sugar levels drop (such as after fasting), the brain detects the low levels and signals the pancreas to produce glucagon. Glucagon stimulates the liver to break down glycogen into glucose and release it into the bloodstream to maintain blood - sugar levels. Insulin is released when blood - sugar levels are high to lower them. Muscle cells absorb glucose when blood - sugar is high for energy or storage, not to increase blood - sugar levels. The liver stores glucose as glycogen when blood - sugar is high, not in preparation for fasting in this context.

Answer:

The brain signals the pancreas to produce glucagon.
