Cellular (Aerobic) Respiration Date:
Let’s get Physical! What are they doing in the video? Why are they breathing so hard? http://www.youtube.com/watch?v=ZLK28BHJDd8 insanity http://www.youtube.com/watch?v=na9ZZ4ZjVa8 richard
Why do cells need energy? http://glencoe.mcgraw-hill.com/sites/dl/free/0078802849/160350/00076705.html
All organisms need energy for: Active transport Cell division Movement Production of proteins Where do we get the energy we need to live? From the food we eat! Food gets broken down so small that it makes its way to all your cells.
Mitochondria are referred to as “the powerhouses” of the cell. Simply stated, the mitochondria make chemical energy in the form of ATP to power the cell.
This energy is stored and released using a molecule called ATP Once the food is inside your cells, the mitochondria take charge and crack the chemical bonds in the food you eat. This energy is stored and released using a molecule called ATP
ADP ATP ATP: energy molecule- basic energy source for all cells living things use ATP to store and release energy like a tiny, fully charged battery ADP made when energy is released from ATP like a tiny, partially charged battery ADP ATP
What about oxygen? What do food and mitochondria have to do with breathing and oxygen and respiration?
“in the presence of oxygen” Aerobic means “in the presence of oxygen” http://vimeo.com/10693405
Cellular respiration…. (aerobic) is the process by which cells take in food (glucose), and oxygen and release carbon dioxide, water, and energy (ATP) http://learn.genetics.utah.edu/content/begin/cells/insideacell/ http://www.teachersdomain.org/asset/lsps07_int_cellenergy/
Cellular (aerobic) respiration in the mitochondria http://www.youtube.com/watch?v=k2oGAru9bSY&list=PLFA52BC091734D2FA&index=2
Cellular (aerobic) respiration has 3 main parts: Glycolysis One molecule of glucose is broken into 2 molecules of pyruvate, a 3-carbon compound Takes place in the cytoplasm Draw a simple diagram of a mitochondrion on the left side of your NB
2. Krebs Cycle Takes place in the mitochondria Pyruvate is broken down into carbon dioxide
3. Electron Transport Chain (ETC) oxygen goes in takes place in the mitochondria turns ADP into ATP (it charges the batteries!) and produces water

Cellular (aerobic) Respiration Equation: ((reactants)) ((products)) C6H12O6 + 6O2 6 CO2 + 6 H2O + energy Glucose + oxygen carbon dioxide + water + energy
Both plants and animals need to break down food to get energy have mitochondria perform cellular (aerobic) respiration
Quickcheck: What are the three parts of Cellular Respiration? Where do they each take place?
Mitochondria have their own DNA and ribosomes!
