1. Back up… Where did the glucose come from? Where did the glucose come from How did the glucose get into your cells?

2. Cellular Respiration A bunch of small steps to break down the glucose If we burned it all up at once, what would happen? Do we want that inside our cells?

3. Who is the powerhouse inside of the cell? Mitochondrion Folded membranes = more room for reactions

4. What reaction is taking place in the mitochondria? Cellular respiration Glucose + oxygen  Carbon dioxide + water + energy AEROBIC process (requires oxygen)

5. C 6 H 12 O 6 + O 2  CO 2 + H 2 0

7. Which molecules store the MOST energy?

8. Who is the energy carrier inside of a cell? ATP Adenosine tri- phosphate

9. WHAT MACROMOLECULE CLASS DOES ATP FIT INTO?

10. Where does ATP store its energy? In the phosphate bonds! So the more phosphates you have, the more energy you have! Why? Phosphates are negatively charged…

12. Comparison purposes ATP ADP

14. Why recharge? If not, we would have to consume our entire body weight in ATP every day!!! That’s a LOT of food!

15. How much energy? One glucose molecule = ~34-36 ATP Each muscle cell has about 600 million ATP molecules 10 million ATPs can be consumed and recharged every second per cell!

16. How long does one ATP last? About 3 seconds… Long term energy storage = ?
