2. NUTRITION: GETTING FOOD TO CELLS

3. Objectives:  Explain the process of digestion  Trace the pathway of food from the mouth to the anus  Cite ways on how human should properly take care of their digest system

4. Recap  What is Genetic Engineering?  How is genetic engineering connected to GMO’s?

5. Warm Up Question  Who among you here have a regular bowel movement?  Does anyone here who always go to the toilet after eating?

6. Video

7. Guide Questions: 1. What is metabolism? 2. How does food travel during digestion? 3. How is mechanical digestion different from chemical digestion?

8. Metabolism – a set of life-sustaining chemical changes that occur within the cells of all organisms

9. Types of metabolism A.Catabolism B. Anabolism

10. Catabolism – breaks down large molecules into smaller ones and releases energy in the process

11. Anabolism – uses energy to build up the chemical components of the cells

12. Ingestion – the process by which an animal takes in food

13. Digestion – the process by which ingested food is broken down into simple substances that can be absorbed by the body

14. Mechanical Digestion- the process wherein the food that has been ingested is physically broken down into smaller pieces

15. Chemical Digestion – the body process the food in such a way that the nutrients it contains can be absorbed in the small intestines

16. Cite ways on how to take of our digestive system.

17. _______------- 1. a set of life-sustaining chemical changes that occur within the cells of all organisms _______2. what kind of acid that our stomach release to help broken down the food. _______3. the process by which ingested food is broken down into simple substances that can be absorbed by the body. _______4. the body process the food in such a way that the nutrients it contains can be absorbed in the small intestines _______5. What is the first step of digestive process of metabolism?

18. Assignment Research work: Identify the digestion process of some other animals (except human)
