Respiration preAP The process by which the_____________ breaks down glucose to produce ATP is called _________________. When the body has oxygen, aerobic respiration can take place and produce ______ energy molecules. There are____ stages of aerobic respiration: o __________________ Glycolysis takes place in _________________ of the cell. Glycolysis is the process where glucose is broken down in ____ __________________ molecules. Pyruvic acid is a ___ __________ molecule. The net gain of ATP molecules in glycolysis is ____ ATP molecules. Following glycolysis, the pyruvic acid moves______ the mitochondria. o __________________ AKA the Kreb’s Cycle The Kreb’s cycle takes place in the _______________. Pyruvic acid enters the citric acid cycle and becomes ____________. As this occurs, 2 ____________ molecules are released. In addition, ____________ molecules are released. Electron carriers such as _______ and ______ are used to pick up energized electrons and pass them to the ETC. o __________________ AKA the ETC http://www.scienc e.smith.edu/depart ments/Biology/Bi o231/etc.html The last step of respiration is the ______________________________ ______________________ or ETC. It takes place in the _________________________________________. In the presence of oxygen, the electron transport chain will produce ___ ______ molecules and ______. The grand total of ATP molecules released from AEROBIC respiration is ____________. ____________ NADH and FADH release the Hydrogen ions to proteins to cross the membrane. This creates a _________________. When ___________enters the ETC, it becomes the final electron acceptor of the Hydrogen ions and creates________. As the hydrogen ions come back across the membrane, ADP is converted into ______ THE BIG PICTURE Anaerobic Respiration (AKA__________________) There are times when your cells are without _______ for a short period of time. When this happens, _____________________ _________________________ is taking place. In anaerobic respiration, the first 2 steps of respiration will take place; however, the ETC will ________________. The grand total of ATP molecules released will be __________. When our cells run out of oxygen and begin fermentation, we build up ____________ _____________. That lactic acid build up in the muscle makes us feel a ___________. Some bacteria also undergo fermentation. They release _______________ and __________ This process is key for the bacteria that create ______________ and ____________. Yeast also undergo this type of fermentation when making _____________. The holes from the _________________ that are released and can been seen when you slice a piece of bread. Comparing Photosynthesis and Respiration
