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

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 _________________________________________________________________________________ It is composed of Glycolysis _______________________
