Hi all,
Today in class we debriefed your homework and described the structure of ATP, and then went on to model cell respiration.
When you think of cell respiration, think about it as coupled reactions. The rule of thumb is: break a bond, make a bond. Meaning, when you break a bond in glucose and release the potential energy stored within it, you have to capture that energy; to do so, you have to make a new bond - for example, a new phosphate bond between ADP and Pi. Now, that energy is captured and stored again, ready to use for the cell.
Homework
I had planned a lecture for tomorrow, but I'm going to adjust the schedule in order to give us a little more time to discuss what happened in class yesterday. For tonight, take a break, or continue working on your post-interim assignment, due Friday.
Thanks
Mr. Hill
