Biology B, Unit 4 Analyzing Digestion Portfolio Checklist

Use the following checklist to ensure that you have included all of the required elements in your portfolio for this lesson.

Review the meal and exercise plans you made in the Food and Nutrition Lesson. Based on comments in the class discussion, make changes to improve your meal and exercise plans. Review the Digestive System worksheet you completed in The Digestive System lesson. Pay particular attention to the chart of macromolecules and the enzymes that break them down. Make a chart that lists the foods in your meal plan, identify where in the digestive system each food is broken down and which enzymes are necessary for your body to do so. Include your meal plan, chart, and exercise plan in your portfolio.
