Unformatted text preview: Cell Respiration in a Nut Shell You eat this DELICIOUS HAMBURGER...and you wonder How you get energy from such a concrete thing...how do you turn the supple pieces of grilled steak into...hmm...technically "36-38 ATP per Glucose molecule"? Well...I'll tell you, b/c I was helping the bio kids on my floor understand it (I was feeling GRACIOUS OK ?) Ok. The Cell is small, but in this case huge...it's got lots...I mean LOTS of goodies... (Look up parts of the Cell) SO MITOCHONDRIA...I think thats how you spell it. Outside of the Mito. is the Cytosol...including some friendly things ( NAD+ , P (hosphate groups), ADP , ATP s, etc ) and oh yeah...GLUCOSE...(duh?)...which is C 6 H 12 O 6 Glycolysis (outside-of-the-Mito. Process): Glucose is huge; too huge...so it has to be broken up to do this you invest 2 ATP. When investing ATP you break off a phosphate and the ATP ADP + Phosphate The phosphates attach to the ends of the glucose molecule (This is done by 2 Rx. But you probably Dont need to memorize that in depth). So you have something that looks like P-C-C-C-C-C-C-P (remember glucose is a 6-carbon chain; this is a new compound) Adolase or Isomerase comes into the picture to split up this new compound. Adolase splits it; Isomerase seems to correct incorrect Isomers of G3P. (Remember ASE means its an enzyme. Just like how OSE implies a sugar.) Adolase splits p-c-c-c-c-c-c-p into 2 c-c-c-p. The name of this is G3P, or also known as something really long (which is in the textbook) But G3P still cant get into the Cell WHYYYY?????...
