CELLULAR RESPIRATION

CELLULAR RESPIRATION

ENERGY

• We get the majority of our energy from our FOOD
• Energy is released from the GLUCOSE in food
• Every time a bond is broken ENERGY is RELEASED
• Glucose is broken down into 2 molecules of
  pyruvic acid in the cytoplasm of the cell
• 2 Molecules of Pyruvic Acid move into the
  mitochondria and are broken down into Carbon
  Dioxide

3
ATP

• adenine tri-phosphate
• The energy currency of the cell
• the battery for energy reactions

GLYCOLYSIS

• releases a small amount of energy.
• It is the first step in cellular respiration.
• If________________ is present Glycolysis leads to
  two other pathways that release a GREAT DEAL OF
  ENERGY.
• If oxygen isnt present a different pathway is
  followed

• Both plant and animals carry out the final stages
  of cellular respiration in the POWER HOUSE OF THE
  CELL!!!
• What is that?
• Glycolysis- glucose is broken down into 2
  molecules of ___________________________.
• It requires energy to get the process started
  therefore ___________________ are needed to begin
  glycolysis.

8

• One of the reactions that are a part of
  glycolysis removes 4 high-energy electrons and
  passes them to the electron transport chain they
  are called NAD (nicotinamide adenine
  dinucleotide)
• This molecule can accept electrons you know this
  because
• When it has accepted electrons it is known as
  NADPH and it holds electrons until they can be
  transferred to another molecule.
