Cellular Respiration

Cellular respiration is a vital process used by all organisms to generate energy for the cell, primarily carried out in the mitochondria to produce ATP. The equation involves oxygen and glucose resulting in carbon dioxide, water, and ATP. There are two types: aerobic (with oxygen, producing 36 ATP) and anaerobic (without oxygen, producing 2 ATP), including alcoholic fermentation and lactic acid fermentation. Alcoholic fermentation releases CO2 without oxygen, often in plants, while lactic acid fermentation occurs in muscle cells, especially during strenuous exercise, converting lactic acid into energy over time.

Presentation Transcript

  1. Cellular Respiration

  2. Cellular Respiration • Process used by ALL organisms perform to make energy for the cell • MITOCHONDRIA perform cellular respiration • Energy that the cells produce is in the form of ATP

  3. ATP • Stands for adenosine triphosphate • ATP is the form of energy that cells use

  4. Cellular Respiration Equation

  5. Cellular Respiration Equation Oxygen + Glucose Carbon Dioxide + Water + ATP

  6. Types of Cellular Respiration • Aerobic – uses oxygen to produce ATP (energy) • Produces 36 ATP • Anaerobic – does NOT use oxygen to produce ATP (energy) • Produces 2 ATP • 2 Types • Alcoholic Fermentation • Lactic Acid Fermentation

  7. Alcoholic Fermentation • When alcohol is produced in a system CO2 is released • This CO2 can be converted in your cells to O2 • The O2 will be used in your system to fuel other reactions • Example: yeast cells and grape juice mixed in a closed container will release CO2, no oxygen required • Often occurs in plants

  8. Lactic Acid Fermentation • Created in your muscles as a result of strenuous exercise • The lactic acid build up will be converted to your cells and used as an oxygen source over time • If you are experiencing muscle fatigue, you may have lactic acid build up because your body has not converted the lactic acid into your cell as quickly as it is building up • This is an ongoing process • Build up of acid can be converted to O2 • Often occurs in muscle cells
