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

Presentation Transcript

  1. CELLULAR RESPIRATION

  2. 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

  4. 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

  5. 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.

  6. 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.

  7. WITH OXYGEN • Cellular respiration is the process _________________________________________________________________________________ • It is composed of • Glycolysis • _______________________ • _______________________
