1. Energy
Notes

2. Energy: ability to do work
Not created or destroyed
Can transform (change form)
Some energy is always lost when energy changes form.

3. How does all this relate to our energy pyramid activity?
Sun started with all the points.
Light energy from sun is converted to chemical energy
Chemical energy = energy stored in chemicals
Stored in bonds
Energy was lost at each level of the pyramid
90% energy lost as heat
Only 10% gained

4. True or false: Energy can be created or
destroyed.
What is chemical energy?

6. Other types of energy Kinetic- energy of motion
Potential- stored energy
(in food in chemical bonds)

7. ATP: Energy of cells

8. ATP is made in the mitochondria!!!
A lot of energy is stored in phosphate bonds
Broken by adding water
Makes ADP (one less phosphate)
Can be recharged by removing water
Energy from
food
Energy for
cellular work
- H2O

10. What is ATP? What is the difference between potential and kinetic energy?

12. Energy flow in a nutshell
Sun
Plants- convert light energy into chemical energy
Consumers- convert food into chemical energy (ATP)
