In eigth/ninth grade Biology you’ve learned about compononts of a healthy diet and how a healthy diet contributes to our well-being. You also learned that our diet consists of nutrients that contain energy (carbohydrates, lipids and proteins) and other components that contain no energy (water, minerals, vitamins).
In this sequence you’re researching on the organs of human digestion and cellular processes taking place in the human digestive system (with special regard to the role of enzymes).
Use your workbook, the IB Biology 2nd Edition Website and other internet resources to …
… explain the properties of enzymes and the role of enzymes in metabolic processes.
… outline the stages of digestion in the human body and the function of the human liver.
… illustrate the biochemical properties of carbohydrates in general and the specific structure of glucose, starch and glycogen
… illustrate the structure of proteins and how amino acids form a three dimensional protein.
… describe and distinguish condensation and hydrolosis reactions.
These animations are useful to begin exploring the different topics:
Organs of digestion
Digestion metabolism overview
Enzyme action and the hydrolysis of sucrose
This independent learning sequence is designed for three hours and two homework sessions. You can individually choose to complete tasks in writing full texts or making notes, visualizing ideas in a mindmap/ concept map/ figures.
We are going to discuss and present results next Tuesday.
