ATP Energy

ATP Guided Notes


  1. State the full name of the molecule that serves as the energy currency of the cell
    Adenosine Triphosphate (ATP) is the molecule used in the cells of every living organism to transfer energy to where it is required.

  2. What type of monomer is ATP?
    An RNA Nucleotide (modified nucleotide, which are the monomer of nucleic acids like DNA&RNA)

  3. Identify the organelle and process that produces ATP
    Adenosine Triphosphate is produced by the mitochondria during the process of aerobic cellular respiration

  4. List 3-4 processes that ATP is used
    1) Active Trasnport

2) Anabolic Reactions

3) Muscle Contractions

4) Movement of the cells or parts within the cell

5) Synthesis of large molecules

  1. Draw and label a diagram of ATP

  2. Explain why ATP is like a spring.
    Shoving all of the negatively charged phosphates together (by creating the bonds) is like compressing the string since their negative charges want to repel from each other.

  3. Describe how energy is released from ATP.  State the name of this process.  Identify the products of this process.
    Energy is released when the 3rd phosphate (end) breaks off to release the energy needed to keep the 3 phosphates so close together. This is accomplished by breaking the bond between the 2nd and 3rd phosphate—called ATP Hydrolysis.


This creates ADP + Pi

  1. What does ADP stand for?
    Adenosine Triphosphate (a water molecule is used to break the bond between the phosphate groups)


Adenosine Triphosphate contains some energy, but not as much as ATP

  1. Describe how ATP is regenerated from ADP.  State the name of this process.  Identify if this processes requires or releases energy.
    ATP is regenerated from ADP from a process called ADP Phosphorylation, where we add phosphate group to ADP.

  • This requires energy

Where do we as humans get the energy needed to perform ADP Phosphorylation?  Where does the energy ultimately come from?
We as humans get the energy neded to perform ADP phosphorylation from the breakdown of food molecules that we consume.
