Chapter 8.1 Energy of Life

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

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)

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
