Title: CELLULAR RESPIRATION


1
CELLULAR RESPIRATION
  • Chapter 9

2
Cellular Respiration
  • The process that releases energy (ATP) by
    breaking down food molecules in the presence of
    oxygen

3
Mitochondria
  • Found?
  • Plant Animal Cells
  • Where respiration takes place
  • Just aerobic parts

4
Aerobic Vs. Anaerobic Respiration
  • Aerobic presence of O2
  • Respiration
  • Anaerobic absence of O2
  • Fermentation

5
Pathway of Cellular Respiration
  • Glycolysis (Cytoplasm)
  • Krebs Cycle (Mito.)
  • Electron Transport Chain (Mito.)

6
Glycolysis
  • Glukus sweet
  • Lysis loosening
  • Occurs in Cytoplasm
  • Breaking one glucose down into 2 pyruvic acids(3
    Carbon) 2 ATP (net)

7
After Glycolysis
  • Anaerobic Fermentation
  • Aerobic Cellular Respiration

8
Fermentation
  • Fermentation will make energy without O2
  • Two types
  • Alcoholic
  • Lactic acid

9
Alcoholic
  • Yeast other microorganisms
  • CO2 causes bread to rise

10
Lactic Acid
  • Animal muscles
  • Happens during vigorous exercise
  • Builds up in muscles causing cramps

11
Krebs Cycle
  • Follows glycolysis
  • Needs oxygen
  • Respiration
  • Occurs in mitochondria
  • Breaks down products of glycolysis into carbon
    dioxide
  • Releasing energy to make electron carriers and ATP

12
Krebs Cycle
13
Electron Transport Chain
  • Inner membrane of mitochondria
  • Electrons move to produce energy

14
ETC
  • Makes ATP 2-3 per electron carrier
  • Oxygen is used as the final electron acceptor
    (H)
  • Forms water

15
Mitochondrial membrane
NADH enters and releases an H and an electron.
16
Mitochondrial membrane
NADH enters and releases an H and an electron.
17
Mitochondrial membrane
The electron travels to the next protein while
simultaneously sending H across the membrane
18
Mitochondrial membrane
The electron is used to form water. The H then
are pumped back into the mitochondria.
19
Mitochondrial membrane
This allows ATP to be made each time a H enters
back in.
20
Totals
  • Glycolysis
  • Net 2 ATP
  • Krebs
  • 2 ATP
  • ETC
  • 32 ATP
  • Total 36 ATP
