PRE-LAB QUESTIONS
1. How do the intake of nutrients and expenditure of energy relate at a metabolic level?
Nutrients are taken into the body as organic molecules in large amounts and broken
down into macronutrients(needed in smaller amounts) to provide energy to the body. A
person’s metabolism increases during physical activity and requires more calories for
energy.
2. Do you think you take in more calories than you burn in a day?
Personally, I do believe I take in more calories than I burn in a day because I am not as
physically active as I should be in order to keep a good balance of the two. Since my
physical activity isn’t as active my metabolism is slower and thus less calories are being
burned.
