Gene Regulation and Protein Synthesis

Posted April 17, 2017 by turtle

Every cell in your body has a full set of genes, or ‘recipes,’ to build many different kinds of proteins (including enzymes). What causes a gene to go from its normal ‘turned off’ state (when it IS NOT building proteins) to its ‘turned on’ state (when it IS building proteins)?  To answer this question, we will zoom in and take a closer look at a gene and its environment to see how and why a specific protein is made.

Sugar Transport Activity

Posted April 17, 2017 by turtle

Have you ever drank a can of soda and suddenly felt more energetic? In this Biograph Virtual Lab, you will use a simulation to explore how the glucose molecules from the soda move from the lumen of your small intestine, across the membranes of your epithelial cells, and into your bloodstream. (Ultimately, the glucose in your bloodstream will move into your body’s cells).

Enzymes: Chew on This!

Posted April 17, 2017 by turtle

Carbohydrates in food are an important source of energy for the body. When you eat starch, it must be broken down into simple sugars before your body can use it for energy. In this Biograph Virtual Lab you will use a simulation to explore the breaking down of starch into sugar. The simulation will enable you to compare and contrast the conversion of starch to sugar both with and without enzymes. This will help you understand the role of enzymes in digestion.
