12222036057Aerobic Respiration-Occurs in the presence of oxygen -Occurs in 3 stages: glycolysis, the Krebs cycle, and oxidative phosphorylation (ETC)0
12222061357Anaerobic RespirationOccurs in situations where oxygen is not available AKA Fermentation Begins with glycolysis and concludes with the formation of NAD+ Two types: lactic acid fermentation & alcohol fermentation1
12222064571Glycolysis-Occurs in the cytoplasm of cells -Beginning of both aerobic and anaerobic respiration -A glucose molecule is broken down through a series of reactions into two molecules of ATP, NADH, and Pyruvate2
12222067902Krebs Cycle-Energy-producing reaction that occurs int eh matrix of the mitochondria -Pyruvate is broken down completely to H2O and CO2 to produce 3 NADH, 1 FADH2, and 1 ATP3
12222071474Oxidative PhosphorylationDuring the aerobic process, the NADH and FADH2 produced during the first two stages of respiration are used to create ATP4
12222074971ChemiosmosisThe coupling of the movement of electrons down the electron transport chain with the formation of ATP using the driving force created by a proton gradient5
12222077874ATP SynthaseAn enzyme that uses the flow of hydrogens to drive the phosphorylation of ADP to produce ATP6
12222081156Electron Transport Chain-Chain of molecules located in the mitochondria that passes electrons along during the process of chemiosmosis to regenerate NAD+ to form ATP -Each time an electron passes to another member of the chain, the energy level of the system drops7
12222086616Fermentation-The process that ends when NAD+ is generated -A Glucose molecule entering the fermentation pathway generates two net ATP per molecule rather than 38 from Aerobic respiration8
12222089729Lactic Acid Fermentation-Occurs in human muscle cells when oxygen is not available -The pyruvate is reduced to lactate by NADH to regenerate NAD+9
12222092288Alcohol Fermentation-Occurs in yeast, fungi, and bacteria -The first stem involves the conversion of pyruvate into two 2-carbon molecules -The process concludes when these molecules are converted to ethanol and NAD+10

Need Notes?

While we strive to provide the most comprehensive notes for as many high school textbooks as possible, there are certainly going to be some that we miss. Drop us a note and let us know which textbooks you need. Be sure to include which edition of the textbook you are using! If we see enough demand, we'll do whatever we can to get those notes up on the site for you!
