Intro to cellular respiration

  1. 1. Intro to cellular respiration Trivia Time Get in groups of 2-3 (work with people you usually do not work with) Take notes while we do this
  2. 2. Which part of a eukaryotic cell isinvolved in cellular respiration? nucleus endoplasmic reticulum mitochondria
  3. 3. Which is not a by-product ofcellular respiration? ATP Water Glucose
  4. 4. In the presence of oxygen, the firststage of cellular respiration is ... Glycolysis The citric acid cycle Electron transport
  5. 5. Define cellular respiration Cell respiration is the controlled release of energy from organic compounds in cells to form ATP.
  6. 6. Overview of Cellular Respiration
  7. 7. In glycolysis, each glucose molecule isbroken down to two molecules of … acetyl coenzyme A pyruvate citric acid
  8. 8. Without oxygen, glycolysis allowscells to make small amounts of ATPthrough a process called ... oxidative phosphorylation • Another way to make ATP electron transport fermentation • There are two types of fermentation: • Lactic Acid fermentation (sore muscles) • Alcohol fermentation
  9. 9. Upon entering the mitochondria, pyruvicacid molecules are converted to _____molecules to be used in the citric acidcycle citric acid • A six carbon compound in the citric acid cycle acetyl coenzyme A • An enzyme joined with two carbons (think of Coenzyme A as an escort for carbon molecules into the citric acid cycle) fumaric acid • An intermediary in the citric acid cycle which is used to produce ATP. It can also be added to candy to make it taste sour and even be used to treat psoriasis.
  10. 10. In a eukaryotic cell, most of the ATPderived from glucose during cellularrespiration is produced by ... Glycolysis The citric acid cycle The electron transport chain
  11. 11. Glucose and _______ are consumedduring cellular respiration. carbon dioxide oxygen water
  12. 12. Most of the ATP produced by the electron transportchain is generated from the oxidativephosphorylation of NADH and ____ . FADH2 flavin adenine dinucleotide FAD NAD+
  13. 13. FAD can be reduced to FADH2
  14. 14. FAD can be reduced to FADH2
  15. 15. What did we learn today?
