Show Worked Solution

Consider Option A:  Enhanced glucagon production

  • Glucagon helps maintain blood glucose by promoting glycogen breakdown.

Other Options:

  • B is incorrect: Glycogen must be broken down to maintain blood glucose.
  • C is incorrect: Insulin decreases during exercise to allow glucose mobilisation.
  • D is incorrect: Cortisol typically increases during prolonged exercise.
