Today we went through the electron transport chain and viewed several on-line animations of this process. This is a difficult part of cellular respiration to understand, so if you were absent today, you must be sure to read this section in the textbook and get extra help. Viewing the animations is also helpful. I can be available for a mini-lesson on this on Friday at lunch if there is enough interest. PS: there is a large group of textbook questions to do (they can be found at the end of the electron transport chain note). These will be discussed on Thursday.
