Students know the role of the mitochondria in making stored chemical-bond energy available to calls by completing the breakdown of glucose to carbon dioxide.

Cellular Respiration
When the mitochondria breaks down food molecules to product ATP. There are three stages in cellular respiration.
 
Equation
C6H12O6+O2--->CO2+H2O+Energy
 
Cytosol
The fluid part of the cell surrounding the organelles
 
Glycolysis
First stage on Cellular respiration and is anaerobic which means it doesn't require oxygen.  Glycolysis is a series of chemical reactions in the cytoplasm of a cell that breaks down glucose and turns it into  pyruvic.
 
Citric Acid Cycle
Is the second step in cellular respiration and is also called the Krebs cycle and is a series of chemical reactions.  It breaks down a molecule and forms ATP and CO2.
 
Electron Transport Chain
The electron transport chain is the last and final step in cellular respiration.  The chain is in the inner membrane of the mitochondrion and passes the electrons to proteins to proteins, slowly realsing some of the energy.  Some of that energy is used for ATP while the rest are in the center of the mitchondrion and makes it have a positive charge in the interior and a negative charge on the exterior. By ahving the negative charge it attracts more postivie ions and helps provides the energy for ATP. When at the bottom of the chain oxygen is the final acceptor and gives us a way for proteins in the electron transport chain to pass along electrons.
 
Cristae
The inner membrane in which where energy storing molecules are produced
 
 ATP
Energy is sotred in the molecule's chemical bonds and can be used quickly and easily by cells

The Relationship Between D, E, F, And G

Proteins connected these 4 standards together because D described how they were made, E described how the proteins were shipped out and stored, and F and G showed how proteins who needed for cellular respiration and photosynthesis in order to create energy.
