  1. Cell respiration Review

  2. It all happens in the cytoplasm and mitochondrion

  3. Anaerobic • Glycolysis is anaerobic • Fermentation and lactic acid fermentation are anaerobic • far less ATP ( only 2 per glucose molecule) is made with out oxygen!

  4. Aerobic Respiration • Most efficient with oxygen! Up to 38 ATP per glucose. • Krebs cycle and electron transport are Aerobic. • happens in the mitochondria of eukaryotic cells. • Electrons have a very strong attraction to oxygen which is why it is at the end of the electron transport chain!

  5. Glycolysis • Translated: glyco= glucose • Lysis= split • Splits glucose from 6 carbons into 2 three carbon molecules called pyruvate. • Happens in the cytoplasm. • Does not require oxygen makes a net gain of 2 ATP and 2 NADH • Requires some energy to get started.

  6. Krebs Cycle • When oxygen is present pyruvate moves into the mitochondrion. Krebs occurs in the matrix of the mitochondrion. • A cycle that breaks apart the 2 carbon molecules and forms carbon dioxide and 3 NADH per pyruvate and 1 FADH2 per pyruvate • 1 ATP directly • It turns 2 times per glucose that goes through glycolysis.

  7. Krebs cycle

  8. fermentation • Occurs in the cytoplasm regenerates NAD+ • Makes a small amount of ATP (2) • 2 types • Alcohol and lactic acid • Bacteria and yeast use alcohol fermentation to make ethyl alcohol and CO2. • Muscles, and microorganisms use lactic acid to make cheese, yogurt and sour cream

  9. Electron transport chain • Most important part of the cell respiration process! • Each NADH can make 3 ATP • Each FADH2 can make 2 ATP • Oxygen is the last electron accepter and forms water at the end when hydrogen bonds with it. • ATP synthase brings hydrogen ions back across the inner membrane of the mitochondrion to for the ATP

  11. Aerobic Cellular Respiration happens in Mitochondria. Three main reactions are involved: • Glycolosis occurs in cytoplasm of mitochondria (requires 2 ATP to start/ makes 2 ATP) • Krebs Cycle occurs in matrix of mitochondria (makes 2 ATP) • Electron Transport Chain occurs in mitochondria; makes majority of ATP (32 ATP) • Out of 38 ATP Produced - energy of 2 ATP required to start the process.
