SI - 2.1.13

Sorry again that I won't be able to hold an SI session tomorrow (Feb. 2) but hopefully this post and the one that I just posted about Membranes and Cell Structure can help.

Today at SI we discussed the Mitochondria and it's importance in Cellular Respiration. Below is a picture that I copied from www.ravenbiology.com

From this picture you should be able to study aerobic respiration try to answer these questions:
What are the 3 steps of Aerobic Respiration?
Where does each of them happen (what part of the cell/mitochondria)?
How many ATP does this part of respiration make?
What molecule enters the Kreb's cycle?
How many total ATP do you get from one molecule of glucose when oxygen is present?
If oxygen is not present what happens?
How many ATP can you get from this type of respiration?
What do animals build up if they don't have sufficent amounts of oxygen present? - think of Dr. Okazaki's story of cross country racing.

You should practice drawing this several times, and without looking at a book label the important steps and other important information.

We also talked about the people that have been mentioned thus far during lecture, below is a list of the different people followed by a list of the things you should know about them. The lists are not in the same order so you will have to match up who did what. Good Luck! Don't hesitate to leave a comment if you have any questions.
