Oriole IB CellResp

cell resp (aero) vocab & definintions

CELLULAR RESPIRATION process used by living organisms to break down their food (glucose) and release energy (ATP)
high-energy electrons negatively-charged atomic particles that are produced during the first three steps and used in step 4 to make ATP
Electron Transport Chain (System) Step #4 of cellular respiration; uses proteins and carriers in the mitochondria to change high-energy electrons into ATP energy
carbon dioxide (CO2) waste gas of cellular respiration that is given off during steps 2 and 3
ATP molecule of cell energy; the energy 'currency' of a cell; produced during steps 1, 3, and 4 but NOT step 2
glucose the main 'fuel' molecule that 'runs' cellular respiration; it's broken apart during Glycolysis into two pyruvates
water the final waste material of cellular respiration; produced during step 4 as Oxygen and Hydrogen are combined
FADH2 coenzyme carrying two high energy electrons; only produced during step 3 and then used during step 4 to make ATP
pyruvate molecules that result from splitting glucose during step 1; they are changed into Acetyl CoA during step 2
acetyl CoA pyruvates get changed into this during step 2 so they can be used in step 3
proton pumps proteins that are used in step 4 to force Hydrogen protons across the inner membrane of the mitochondria
Hydrogen protons pumped across the inner membrane of the mitochondria during step 4 so that ATP can be made
Coenzyme A used during step 2 and attached to the acetyl group so it can be carried to and used in step 3
oxygen (O2) element that must be present for steps 2, 3, and 4 to work; used in step 4 to make water
enzymes these 3-D proteins are necessary for all four steps of cellular respiration to work at normal cell temperatures
mitochondria (matrix) location in the cell where steps 2, 3 and 4 take place; the 'powerhouse' of the cell
OAA (oxaloacetate) the beginning material that step 3 always starts with; it is reproduced again at the end of that step
Glycolysis Step #1 of cellular respiration; literally means that sugar is being split apart
NADH coenzyme that carries a high energy electron; produced during steps 2 and 3, then used during step 4 to make ATP
Intermediate (Link) Reaction Step #2 of cellular respiration; changes pyruvates into acetyl CoA so they can be used in step 3
cytoplasm watery insides of a cell; where step 1 of cellular respiration takes place
Krebs Cycle Step #3 of cellular respiration; starts with OAA, attaches Acetyl CoA, then releases NADH, FADH2, CO2, and remakes OAA
ATP synthase enzyme used during step 4 to put together the energy molecules of ATP; works when Hydrogen protons move through it
