Question

Quizplus · Accepted Answer

When an individual fasts, their body needs to increase glucose production to maintain normal glucose levels. Glucagon is the hormone responsible for promoting glucose production and release from the liver, and its levels increase during fasting. Insulin, on the other hand, is responsible for lowering glucose levels, and its levels decrease during fasting. Secretin and gastrin are hormones that regulate digestive processes, which would not be active during fasting, and glucose levels would be expected to decrease during fasting, not increase.
