You will need to include a picture of the label with this handout and your other drawings / charts. The writer can get or choose any nutrition label.

2. Write down the total grams for each of the biomolecules in the table below. Multiply by the given multiplier to calculate the amount of energy for each category. Add up the total calories. Calories is used as a unit for energy.

Analysis

 

3.  Calculate the percentage contribution to the total mass for each biomolecule and make a pie chart of

       this information (you may draw it or use Excel, etc.) Color code the chart with carbohydrates in

       blue, protein in green, and fat in red. Create a key or legend and a title. 

 

 

 

 

4. Calculate the percent contribution to the total energy for each biomolecule and make a chart of this information. Color code the chart with carbohydrates in blue, protein in green, and fat in red. Create a key or legend and a title.

 

 

 

Conclusion

5. Was the biomolecule with the highest calorie contribution the same as the biomolecule with the highest mass contribution?
