Question

Explain why an athlete in a race will be given a glucose drink rather than a piece of bread.

Answer 1

maybe becuse glucose is a simple sugar which will not take long to digest while bread which is a complex sugar has to be broken down into simple sugar

Answer 2

Because glucose is what we need for energy,and atheletes ofcourse needs instant energy by consuming glucose drink,but if bread or any other food is given it will take time to breakdown and will provide energy after hours.
