Unit 5 Review - Cell Energy - Practical Biology

How many phosphate molecules does ATP have?

• 1

• 2

• 3

• 4

How do cells get energy out of ATP?

• They add more and more phosphates to the molecule.

• They break the bond between the second and third phosphate and energy is released from the bond being broken.

• They add carbon atoms because carbon can make 4 bonds.

• Cells cannot use ATP for cellular processes.
