CATALYST 1.How many Turkeys are used in Missouri? 2.Which state uses almost twice the amount of turkeys as California? 3.Which state uses the most Turkeys?

CATALYST 1.How are each of these organisms using energy? 2. In what other ways do organisms use energy?

Essential Question How does an animal access the energy in sunlight?

Objectives: I CAN… □Explain why organisms need a supply of energy □Describe how energy is stored and released by ATP

The Need for Energy

All living organisms must be able to obtain energy from the environment in which they live. CELL ENERGY

How do plants get energy? How do animals get energy? Sunlight Eating plants or other animals Take Notes! Topic: Cell Energy

Plants and other green organisms are able to trap the light energy in sunlight and store it in the bonds of certain molecules for later use. CELL ENERGY

Other organisms cannot use sunlight directly. They eat green plant and other living organisms. In that way, they obtain the energy stored in plants. Topic: Cell Energy

Autotroph Heterotroph Organisms that produce their own food/energy. Ex. Plants Organisms that obtain their energy from eating plants and other animals. Ex. Humans Take Notes! Topic: Cell Energy

Active Transport Cell Division Movement of cilia or flagella Production, transport, and storage of proteins Think about it…… WHY DO CELLS NEED ENERGY?

The name of this energy molecule is adenosine triphosphate or ATP for short. There is a molecule in your cells that is a quick source of energy for any organelle in the cell that needs it. Topic: Cell Energy

The energy molecule for cells ATP = adenosine triphosphate ATP is made of one adenosine molecule + a ribose sugar + 3 phosphate groups Topic: Cell Energy Take Notes!

AMP= Adenosine Monophosphate  Little energy ADP= Adenosine Diphosphate  More energy ATP= Adenosine Triphosphate  ALOT of energy Adenosine P PP PPP Topic: Cell Energy Take Notes!

The energy of ATP becomes available to a cell when the molecule is broken down. Adenosine PPP P P PP Adenosine triphosphate (ATP) Adenosine diphosphate (ADP) Topic: Cell Energy

Then, when the phosphate bond is broken and the energy released, the cell can use the energy for activities such as making a protein or transporting molecules through the plasma membrane. ATP ADP Protein P Energy HOW DO CELLS GET TO THE STORED ATP??

When ATP has been broken down to ADP, the ADP is released from the binding site in the protein and the binding site may then be filled by another ATP molecule. HOW DO CELLS GET TO THE STORED ATP??

How do cells use ATP for energy? When ATP is broken down energy is released Cells capture and use this energy Proteins are used in this process Topic: Cell Energy Take Notes!

Reflect Answer the essential question. How does an animal access the energy in the sun? Write 3-5 sentences.
