  1. Energy and Life Chapter 8.1

  2. Autotroph • Organism that makes it’s own food • Ex: plants

  3. Heterotroph • Organism that does not make it’s own food and must obtain energy from the food it eats. • EX. Humans, bugs, and dogs.

  5. ATP • Also known as adenosine tri-phosphate • Principal chemical compound that cells use to store and release energy

  6. ATP • ATP consists of three parts • Adenine group • Ribose(5 carbon sugar) • Three phosphate groups

  7. Storing Energy • ADP- (adenosine di-phosphate) looks just like ATP minus one of the phosphate groups. • When a cell has energy available it just adds the phosphate group to the ADP • This turns ADP into ATP

  8. Releasing Energy • To release energy you have to break the bonds between one of the phosphate groups in the ATP. • In other words you lose a phosphate • ATP turns into ADP

  9. Uses of ATP • You use ATP to: • Contract a muscle • In active transport • In protein synthesis

  10. RECAP • The key to ATP is its third phosphate group and its ability to be added or removed. • Cells only keep a small amount of ATP on hand because it’s not actually good at storing energy, instead we use glucose.
