  1. CELLULAR RESPIRATION

  2. CHEMICAL PATHWAYS OBJECTIVES: 9.1 Explain what cellular respiration is. Describe what happens during the process of glycolysis. Name the two main types of fermentation.

  3. ____ provides living things with the chemical building blocks they need to grow and reproduce. • One ____ glucose releases ____ calories of heat energy. • A ____ is the amount of energy needed to raise the temp of 1g of water 1 degree Celsius. • A capital C is a ___________ (1000 calories).

  4. The process of releasing the energy in glucose begins with ____________. Glycolysis releases only a _____ amount of energy. If __ is present glycolysis leads to two other pathways that releases a lot of energy.

  5. ________________is the process that releases energy by breaking down _______ and other food molecules in the presence of oxygen.

  6. Mitochondria The _____ cycle takes place in the cytoplasm of the mitochondria. (study diagram on p. 222)

  7. Glycolysis is the process in which one molecule of glucose is broken in half, producing two molecules of ___________, a 3-carbon compound. Glycolysis gives the cell a net gain of __ ATP. Read glycolysis p. 223

  8. ___________ (anaerobic-no oxygen) has two main types: _________: by produces are carbon dioxide and ethyl alcohol. _______________: regenerates NAD+ so that glycolysis can continue. Lactic acid build up is the ache you feel in your muscles when you exercise.

  9. THE KREBS CYCLE AND ELECTRON TRANSPORT OBJECTIVES: 9.2 Describe what happens during the Krebs cycle. Explain how high-energy electrons are used by the electron transport chain. Identify three pathways the body uses to release energy during exercise. Compare photosynthesis and cellular respiration.

  10. Because the pathways of cellular respiration require ______, they are said to be _______. During the Kerbs cycle, _______ acid is broken down into carbon dioxide in a series of energy-extracting reactions. ____________________uses the high-energy electrons form the Krebs cycle to convert ADP to ATP.
