14. What we’ve figured out so far…
FOOD + O2 + H2O
And now we know that:
ENERGY for LIFE
FOOD is made of proteins, fats and carbohydrates.
But… are ALL these “inputs” used to get energy?
CO2 + H2O + nitrogen waste
Let’s try to narrow it down. Which of these molecules provide our energy? In other words, which is our “fuel”?

What happens to the food we eat? Have students diagram on Doodle Sheet or white board what happens to the hamburger and bun? Go through each type of molecule as a review of that the monomers are.
BLOODSTREAM
What happens to food after we swallow it?
First, breaks into its component polymers.
Do you think it stops there?
No, the polymers get broken into their monomers.
Then THOSE are absorbed in to bloodstream.

19. Which molecule do you think might be our likely fuel? Why?
THESE are what our cells absorb from the intestine:
Which molecule do you think might be our likely fuel? Why?

20. Some other fuels: molecules that release energy COAL:
Which food molecule is most similar to these???
Doodle E. GLUCOSE - our most important and readily available fuel.
Coal and wood are fuels that give off energy… so does glucose
WOOD:

21. What else do these fuels need in order to burn
What else do these fuels need in order to burn? What is the other reactant in fire? O2
What else do WE need to take in besides our fuel (food!)?
O2!
Doodle F: So O2 is definitely one of the most important reactants in our energy- releasing reactions.
COAL:
WOOD:
Besides glucose we need oxygen to use glucose for energy

22. Doodle H. WHERE DOES GLUCOSE GET REARRANGED IN OUR BODIES?
In our cells, in the MITOCHONDRIA.

23. Doodle I. What is the problem with having a reaction like this happen in a cell? Yes, too much energy all at once! It would cook your cells!! In combustion reactions, the fuel molecules are rearranged all at once, in one big step, so all of the energy is released at once. Doodle J. Suggest a way cells might solve this problem.

24. Doodle J: Draw a picture to suggest a way cells might solve this problem of getting too much energy all at once.

26. Other issues:
How can a cell move energy from the mitochondria to where it’s needed??
Doodle K. These problems are solved by a little molecule called ATP. Think of it as a battery of cellular energy.

Captures energy released when glucose is rearranged
Moves energy from mitochondria to where it’s needed

Cellular Respiration
Living things get energy by rearranging food and oxygen molecules
How do we, safely, get energy from food?
Model Ideas
Living things rearrange the atoms in food, specifically glucose (C6H12O6) and oxygen (O2) into carbon dioxide (CO2) and water (H2O)
(C6H12O6 + O2) have more energy than (CO2 + H2O) so this rearrangement releases energy

Model Ideas
Living things rearrange food (specifically glucose - C6H12O6) and O2 into CO2 and H2O
(C6H12O6 + O2) have higher energy than (CO2 + H2O) so this rearrangement releases energy.
Rearrangement occurs in steps to slowly release energy by a chemical reaction called cellular respiration
Usable energy is released in the form of ATP
