1.

In our jumping jacks lab, you observed how exercise increased the amount of CO₂ that you exhaled. Explain what happened in the jumping jacks lab, using the following terms (1/2 point each). PLEASE CAPITALIZE (ALL CAPS) EACH OF THESE TERMS WHEN YOU USE THEM. potential energy kinetic energy glucose carbon dioxide cellular respiration lungs chemical energy thermal energy mitochondria oxygen ATP bloodstream
2.

Bonus! Jumping jacks ‘burn’ kilocalories at a rate of 450 per hour (3x more than walking; slightly fewer than swimming). The nutrition label on my tropical punch container says that it has 60 calories per 8-oz cup (one serving). Assuming that I could absorb every last calorie from the tropical punch into my cells (which is not actually possible), how many 8-oz cups of punch would I need to replenish my energy supply after jumping for 5 minutes? Show your work with labeled numbers.
