What is ATP and what does ATP stand for?

• ATP is the primary molecule that is used for energy in living things.

• Adenosine triphosphate

What is ATP made up of? Draw a picture.

• ATP is made up of 1 adenine base, 1 ribose sugar, and 3 phosphate groups.

Where is the energy stored?

• Most energy in ATP is stored in the chemical bond in-between the 2nd and 3rd phosphate group.

What must break off ATP to produce energy?

• The 3rd phosphate group!

What is formed when this happens?

• ADP—Adenosine diphosphate + a free phosphate

What the equations for energy storage and energy release.

• Energy storage:– ADP + P + food energy ATP

• Energy release:– ATP ADP + P + ENERGY!

What are two common biological molecules that make up ATP?

Where else is each found?

• 1) Ribose sugar (found in RNA)

• 2) Adenine (found in DNA & RNA)

Name some things that the cell might generate energy for.

• Active transport (across cell membrane)

• Endocytosis

• Movement

Where does the cell get the energy that it stores as ATP?

• FOOD!
