Illustrate and describe the process of how insulin works. Make sure to include: insulin, glucose, insulin
receptor, cell membrane, and glucose channel protein
Be able to calculate food energy (in kilojoules) from food calories (Cal).
1 Calorie = 4.186 Joules
1 kJ = 1000 J
Example:
If Marshmallows have 0.55 Cal/g, what is its food energy in kilojoules?
1. (0.55 Cal/g) x (4.186 J) = 2.30 J
2. (2.30 J) / (1000 J) = 0.0023 kJ
Now you try:
If Peanuts have 3.4 Cal/g, what is its food energy in kilojoules?
