Glucose ATP!But how?!?
Mrs. Jandy
So… for a quick recap• Cellular respiration!
ADP + 6O2 + C6H12O6 6CO2 + 6H2O + ATP oxygen + glucose carbon + water +ENERGY! dioxide
• So, cellular respiration turns glucose (chemical energy) in to ATP (usable energy)
Glucose
ATP
• ATP is energy the cell can use to do work!
• Like currency/money: Only this one molecule (ATP) is the right type of energy the cell can use
• You can’t buy groceries in Apopka with Japanese ¥!!!
• Energy is stored in the phosphate bonds
• Energy is released when the phosphate bonds are broken
ATP – Adenosine TriphosphateAdenosine diphosphate [ADP]
KNOW THIS SLIDE!!!
ADP
In order to turn Glucose into ATP there are three steps!
1) Glycolysis
2) Krebs Cycle
3) Electron Transport Chain
Pause, Think, and Take Notes!• What is ATP?
• Where is energy stored in ATP?
• What are the three steps needed to turn glucose into ATP?
Pause, Think, and Take Notes!• What is ATP? ATP is the ONLY molecule that the cell can use for energy to do work• Where is energy stored in ATP? Energy from ATP is stored in the phosphate bonds• What are the three steps needed to turn glucose into ATP? Glycolysis, The Krebs Cycle, Electron Transport Chain
Glycolysis• Occurs in the Cytoplasm
• No oxygen required
• 1 glucose 2 pyruvate + 2 ATP + 2 high energy molecules (NADH)
• BUT WE NEED MORE!!!!!
ATP COUNT: 2
The Krebs Cycle
• Occurs in the Mitochondria
• Requires Oxygen
• 2 pyruvates 2 ATP+ 8 high energy molecules (NADH, FADH)
ATP COUNT: 4
Electron Transport Chain• Occurs in Mitochondria cell membrane
• Requires Oxygen
• 10 high energy molecules (NADH, FAD) 30 ATP
• Uses enzyme called ATP Synthase
ATP COUNT: 34
Let’s wrap it up!• Glycolysis, Krebs Cycle, and ETC…
1 glucose 34 ATP!!!!!
Anaerobic Respiration• What happens if we have to make ATP and don’t have oxygen???
• No Oxygen = Anaerobic Respiration!• Only GLYCOLYSIS can take place which makes 2 ATP!• Two kinds of anaerobic respiration• In animals- Produces 2 ATP + Lactic Acid (sore muscles!)• In yeast- Produces 2 ATP + Ethyl Alcohol (yes, that alcohol)
Aerobic Respiration• Have oxygen = Aerobic Respiration
• What we do on a daily basis
• Glycolysis, Krebs Cycle, and ETC can occur
• Makes 34 ATP!
Anaerobic Respiration Aerobic Respiration
No Oxygen Oxygen
Makes Lactic acid or Alcohol Makes H2O and CO2
2 ATP 34 ATP
