1. Chapter 8.1 Energy of Life

2. Autotrophs and Heterotrophs
Autotrophs (Producer)- Use light energy to make their own food
Example: ?
Heterotrophs (Consumer)- obtain energy from the foods that they consume

3. Chemical Energy and ATP
Energy comes in many forms, including light, heat, and electricity.
One of the principal chemical compounds that cells use to store and release energy is ADENOSINE TRIPHOSPHATE (ATP)

4. What does ATP consist of?
Adenine
Ribose (sugar)
Three phosphate groups
Able to store and release energy
Store-ADP (adenosine diphosphate)
Type of Energy = ?
Releasing Energy-characteristics of ATP make it exceptionally useful as the basic energy of all cells
