1. Glycolysis, Cellular Respiration and the Cell
Aerobic Energy Processes of the Cell

2. Five main forms of energy:
             
Mechanical - associated with motion.
Heat - internal motion of particles.
Chemical - bonds atoms and ions together.
Electromagnetic - moving electric charges.
Nuclear - in the atomic nucleus.     
Nuclear fission     
Nuclear fusion

5. Equations The chemical equation for respiration is:
C6H12O6 + 6O2  6CO2 + 6H2O
Glucose + Oxygen  Carbon Dioxide Water + Energy

6. Where does it take place?
Location of GLYCOLYSIS
STAGE 1 in cytoplasm w/ enzymes
Location of Respiration
Mitochondrion
STAGE 2 Cellular Respiration
STAGE 3
Electron Transport

7. The molecule

8. The MITOCHONDRION is the powerhouse of the cell
The MITOCHONDRION is the powerhouse of the cell. It is the site of respiration. It has a double membrane. From this view you can see very little >>>>>>>>>>
The white folded structure is the inner membrane. Most of AEROBIC RESPIRATION occurs along this membrane.

9. The outer membrane is cut to get a better look
The outer membrane is cut to get a better look. With the outer membrane removed it is much easier to see the contents of the mitochondrion.

10. The inner membranes is ruffled/folded.
It has a very large surface area.
These ruffles are called cristae.
Mitochondria have their
own DNA and manufacture some their
own proteins. It is thought that the
mitochondrion evolved from symbiotic
bacteria that took up residence inside
the first eukaryotic cells.

15. Glycolysis & Respiration Summary (ATP from glucose)
Glycolysis Stage I ATP NADred*
Stage II NADred
Kreb's Cycle Stage III 4ATP, 6NADred, 2 FADred*
Subtotal ATP*, 10NADred, 2FADred
Total ATP ATP –*4ATP = 36ATP
*(1 NADred = 3 ATP; 1FADred = 2 ATP)
