In the Ex Phys lab, Jules is running on the treadmill at a speed that is 80% of her HR_max. Ian is observing the test while sitting in a chair and is considered at rest. Who is using a higher percentage of CHO’s than Fats as their primary energy source?

• Ian

• Jules

• Both are using the same amount of these substrates for energy

• Cannot determine based on information given

1. Muscle glycogen is primarily used for _____.

• 1. Making ATP in the muscle cells

• Creating ATP from fat

• 1. Creating ketones for the brain

• 1. Managing blood glucose levels

• Fueling muscle contraction, ex. during exercise

1. During which of the following activities would the process of glycogenolysis for muscle glycogen be significantly increased?

• 1. Sitting down in Mr. Patek’s class

• 1. Doing 15 Burpees every time Mr. Patek says “ATP”

• 1. While sleeping

• 1. Breakdancing at the Marc

• 1. Walking your dog at a casual pace (light intensity)

1. Once a glucose molecule is “plucked” from liver glycogen, that glucose will immediately undergo glycolysis to make pyruvate and ATP.

• True

• False
