Transcript of Cellular Respiration and Fermentation

Cellular Respiration and Fermentation
By: Mr. Arata
5 December 2014

Photosynthesis
stores
energy in
glucose
Cellular respiration and fermentation release energy from glucose (and make ATP)
(Carbon Dioxide + Water)
(Oxygen + Glucose)
PHOTOSYNTHESIS
(in producers)
CELLULAR RESPIRATION
(in producers and consumers)
(Solar Energy)
(Chemical Energy)
Both are processes that
release energy from food
and
make ATP
molecules (the 'batteries' of the cell)
Cellular respiration is '
aerobic
' because it
requires oxygen
Fermentation is '
anaerobic
' because it
does not require oxygen
Cellular respiration takes place in and around the mitochondria
Three step process
1. Glycolysis
2. Krebs Cycle
3. Electron Transport Chain
Results: 36 molecules of ATP per glucose
When oxygen is not available, fermentation occurs
Two step process
1. Glycolysis
2. Alcoholic Fermentation (in yeast) OR Lactic Acid Fermentation (in most organisms)
Results: 2 molecules of ATP per glucose
Your body can do both processes
Cellular respiration most of the time ('long-term')
Lactic acid fermentation in short bursts ('quick')
Welcome!

Today, you will need a pen(cil), a note guide, and seatbelt.
No PowerPoint today. Sorry.
Hope your seatbelts are fastened...
Photosynthesis takes place in the chloroplasts
Today (12/5) and Monday (12/8) - Discuss cellular respiration and fermentation
Tuesday (12/10) - Review for unit test
Wednesday (12/10) - Molecules and Cells Unit Test
Things on the unit test:
Cell Structure / Function (chapter 7)
Photosynthesis (chapter 8)
Respiration / Fermentation (chapter 9)
Cell Growth and Division (chapter 10)
Homework reminders:
Organelle labeling and coloring due Monday (12/8)
Molecules and Cells Unit Test - Wednesday (12/10)
Begin working through semester exam study guide
