Cellular (Aerobic) Respiration Date: S

Let’s get Physical! S What are they doing in the video? S Why are they breathing so hard? S http: //www. youtube. com/watch? v=ZLK 28 BHJDd 8 insanity S http: //www. youtube. com/watch? v=na 9 ZZ 4 Zj. Va 8 richard

Why do cells need energy? http: //glencoe. mcgrawhill. com/sites/dl/free/0078802849/160350/0 0076705. 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. S

• 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.

• 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

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 S

What about oxygen? S What do food and mitochondria have to do with breathing and oxygen and respiration?

Aerobic means “in the presence of oxygen” http: //vimeo. com/10693405 S

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/ S http: //www. teachersdomain. org/asset/lsp s 07_int_cellenergy/

Cellular (aerobic) respiration in the mitochondria http: //www. youtube. com/watch? v=k 2 o. GAru 9 b. SY&list=PLFA 52 BC 091734 D 2 FA&index=2 S

Cellular (aerobic) respiration has 3 main parts: 1. 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)) C 6 H 12 O 6 + 6 O 2 6 CO 2 + 6 H 2 O + 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 three parts of Cellular Respiration? Where do they each take place?

Mitochondria have their own DNA and ribosomes!
