Criticize and Revise

Your teacher will show you an animation of this process. It is a simplified version of what actually happens in the mitochondria. Pay close attention and be ready to explain the process to a partner.

Now that you have completed the activities on the mitochondria and seen the scientists' model in the animation, try to explain how the mitochondria carries out cellular respiration to a partner.

Describe:

1. What the mitochondria needs to transform energy.

2. What is given off as a by-product.

3. What chemical change takes place within the mitochondria that provides energy for the cell processes.

Think back to the desert island.

Do you have new ideas now about why the person was losing weight?

Can you explain what was happening down to the cellular level now? Write your thoughts.

Think back to the very first lessons onenergy and on all the lessons on digestion and the cell. Go back to your previous drawing of the mitochondria also. Compare what you drew then and what you know now.

Complete the drawing in your lab book giving as much information as possible. Label your drawing.
