Biochem 4: Metaboism

  1. 1. Bellringer  Describe how acids affect proteins in the body.  What do you think people mean when they say someone has a fast metabolism?
  2. 2. Agenda  Collect Homework  Guided Notes: pH and Protein  NOTES: Metabolism  Anabolic vs Catabolic reactions  Photosynthesis  Cellular Respiration  Fermentation
  3. 3. Metabolism  The word metabolism refers to all of the chemical reactions that take place within living things  There are 2 types of metabolic reaction 1) Anabolic Reactions  Building large molecules from small ones  Anabolic reactions require energy 2) Catabolic Reactions  Tearing apart large molecule into small ones  Catabolic reactions release energy
  4. 4. CAT = Destruction
  5. 5. Photosynthesis  Photosynthesis is a chemical reaction in which plants combine water and carbon dioxide gas to create glucose (sugar).  Oxygen gas is given off as a waste product.
  6. 6. Photosynthesis is Anabolic  Photosynthesis is considered an anabolic process for 2 reasons  It combines small molecules to make large. Making a single molecule of glucose requires 6 waters and 6 carbon dioxides.  It requires energy. Photosynthesis is only possible when the plant absorbs energy from the sun.
  7. 7. Catabolic Reactions  In order to use the energy stored in glucose, the molecule must be broken apart.  There are 2 types of catabolic reactions  Respiration: Aerobic (requires oxygen)  Fermentation: Anaerobic (Doesn’t require oxygen)
  8. 8. Cellular Respiration  Cellular Respiration uses oxygen to break down food. When glucose is broken down it releases energy.  Water and Carbon Dioxide are created as waste.
  9. 9. Respiration explains why animals exhale CO2
  10. 10. Compare photosynthesis & respiration . . .
  11. 11. Fermentation  Fermentation is a way to break down glucose without using oxygen, but produces less energy  Fermentation is done by many bacteria, and by animals when they are “short of breath”.  2 types of fermentation  Alcohol: Done by fungi and bacteria  Lactic Acid: Done by bacteria and animals
  12. 12. Alcohol Fermentation  Alcohol fermentation produces 2 waste products  Carbon Dioxide Gas  Alcohol  Beer is created by allowing yeast to digest barley grain. In fact, all alcoholic beverages are created by the digestive process of microscopic organisms
  13. 13. Lactic Acid Fermentation  Lactic Acid fermentation is used in the production of dairy items like cheese and yogurt.  Humans also produce lactic acid in their muscles during intense exercise. The buildup of this acid explains why your muscles burn after working out.
