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
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 isn’t 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.



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.
WITH OXYGEN

Cellular respiration is the process
