This Power Point contains information about cellular respiration, including glycolysis (which takes place in the cytoplasm) and the Krebs Cycle (which takes place in the matrix of the mitochondria). The electrons produced in the Krebs Cycle move through the inner membrane, or cristae, of the mitochondria. The motion of these negatively-charged particles attracts protons (H+), and eventually a high concentration of protons within the membrane is available to drive 'proton pumps' that power an enzyme, ATP synthase, leading to the production of more ATP:

You can download the actual Power Point here.

You can get a PDF file of the Lecture Guide based on this Power Point here.

Time's running out to complete class work. Previously-assigned work must be handed in this week. Work assigned after the 10th will be accepted until Thursday the 18th.
