1. 1 noodle broken into 3 pieces
Write and Create
Adenosine triphosphate (aka ATP) is the preferred energy molecule for living things.
Create a model of ATP:
1 large marshmallow
3 small marshmallows
1 noodle broken into 3 pieces

2. Draw the model you created on the left side of your chart.
Create and Label
Draw the model you created on the left side of your chart.
ATP has these parts to it:
Adenosine
3 Phosphate groups
Covalent bond between phosphate groups
Label your diagram with the parts.

3. Re-Label the following parts: Large marshmallow—adenosine
Re-assemble your ATP molecule. Draw the correct model on the right side of your chart.
Re-Label the following parts:
Large marshmallow—adenosine
3 small marshmallows—phosphate group
3 noodle pieces—covalent bonds
Outermost noodle—highest energy bond to innermost noodle—lowest energy bond

4. Adenosine Triphosphate
What Is ATP?
Write
Energy molecule used by all Cells
Adenosine Triphosphate
Organic molecule containing high-energy Phosphate bonds

5. Chemical Structure of ATP
3 Phosphates
Ribose Sugar

6. What Does ATP Do for Organisms?
Write
What Does ATP Do for Organisms?
It supplies plants and animals with ENERGY!

7. How Do Organisms Get Energy From ATP?
Write
How Do Organisms Get Energy From ATP?
By breaking the high- energy bond between the last two phosphates in ATP

8. What is this Process Called?
HYDROLYSIS because H2O must be added
H2O

9. ATP Summary:

Write an analogy (pick one of the following). ATP is like:___________, because_________
a phone battery
a one dollar bill
gasoline
a gun that can only fire a single shot
a turnstile at a concert

10. When is ATP Made in Organisms?
Write
When is ATP Made in Organisms?
During Cellular Respiration that takes place in both Plants & Animals

11. Write
Cellular Respiration
Includes 3 pathways that require glucose and oxygen
Breakdown of one glucose molecule results in 36 to 38 ATP molecules
