Lab 17 Nutrition BIO202L
Student Name: Randi Weight
Access Code (located on the lid of your lab kit): AC-ZYVLDM8
Pre-Lab Questions:
1. How do the intake of nutrients and expenditure of energy relate to a metabolic level?
All of the nutrients you take in in a single day equal the amount of energy you are able to put
out in a single day. The more calories and activity you have during the day, the more likely you
are to have excess energy.
2. Do you think you take in more calories than you burn in a day? Why or why not?
Yes. I am not extremely active. I am a mom, so I chase my kids a bit. But I also enjoy junk food
and soda way too much.
