Before going into cell respiration, the nitrogen needs to be removed as waste. This nitrogen waste is then sent to the kidneys, which has the major function of removing nitrogen waste Ingest material – either used as energy or for building blocks. Graphic on blackboard, print it, review it Glucose comes into glycolysis (breaking down glucose), it is happening in the cytoplasm Arrows out of glycolysis: o NAD takes away hydrogen o Arrow goes directly to ATP, no electron transfer system etc, on-site production of ATP is called substrate phosphorilation o 2 3 carbon molecules, the junction is called the “make ready step”, to enter in the kreb cycle. Only need 2 carbons, so the other is oxidized into CO2 o Then the 2 carbons go into kreb cycle Graphic in textbook Stairstep- electrons giving off energy as they go from lower to lower energy levels. Graphic on blackboard Summary graphic It tells you what is in mitochondrion and what is not in mitochondrion. The -2 ATP is because it took 2 ATP to use in glycoloysis FADH- we don’t talk about this molecule because mrs. Desaix thinks it is not necessary for our conceptual discussion. Cell Cycle- (aka life of a cell)
