Transcript of The Breakdown of Glucose In a Cell

1. Glycolysis 3. The Electron Transport Chain 2. The Krebs Cycle The Breakdown of Glucose In a Cell Fermentation Important Notes : (cc) photo by Franco Folini on Flickr By Yushan Wu Aka: Cellular Respiration There are 3 stages in Cellular Respiration: Glycolysis Krebs Cycle Electron Transport
Chain This is the first stage of Cellular Respiration.
Glycolysis happens in the Cytoplasm. Glucose and Oxygen enter the animal cell and
the Glucose is broken down into 3 carbon atoms
(Pyruvate). 2 ATP molecules are also produced. Why? Glucose needs to be broken down into
3 carbon atoms (pyruvate) in order to
diffuse through the membrane and continue
on to the Krebs Cycle in the Mitochondrial
Matrix. Glycolysis in
Cytoplasm The Krebs Cycle In
Matrix The Electron
Transport Chain In
Cristae Now, there is another route where the pyruvate
goes when there is no oxygen in the body, and
that is Fermentation. There are 2 types of Fermentation:
~Lactic Acid Fermentation ~Alcoholic Fermentation Happens in the Cristae or
the Inner Mitochondrial
Membrane. What comes in? Hydrogen Why? To Make 32 ATP for the Body. Lactic Acid Fermentation Alcoholic Fermentation Welcome to the second stage
of Cellular Respiration This stage happens in the
Mitochondrial Matrix. What Comes In? The Pyruvate from Glycolysis enters the matrix and is turned into COA The NADH, NADH2, and FADH2 Carriers
are made here. Getting rid of Carbon Dioxide
in the Krebs Cycle. Some ATP molecules are
also produced here Did you Know? The reactants for Photosynthesis:
CO2, H2O, and Energy are the products
in Cellular Respiration while... The reactants for Cellular Respiration:
Glucose (C6H12O6) and Oxygen (O2)
are the products of Photosynthesis. * Pyruvic Acid + NADH = Alcoholic + CO2 + NAD+ * Pyruvic Acid + NADH =
Lactic Acid + NAD+ * Produced in your muscles during rapid exercise when the body cannot supply enough oxygen to the tissues. Anaerobic- "Not in Air" * Produces Carbon Dioxide as well as alcohol ATP Molecule: *Energy is stored in the ATP molecule
(Adenosine Tri-Phosphate)

*Energy is released when the bond
between the 2nd and 3rd phosphate is
broken. When the bond is broken off
the molecule turns into ADP.
(Adenosine Di-Phosphate) END Bond Is Broken Here Total: 36 ATP molecules
