Energy Of Cells Cellular Respiration
Organisms obtaining food • Autotroph: An organism that makes it’s own food • Ex. Plants, Algae • Heterotroph: An organism that obtains food by eating autotrophs. • Ex. Human, Cow
Energy Kinetic Potential Stored Energy Chemical Energy Atoms arranged to store energy • Energy of motion • Thermal Energy • Random Molecular Motion
Cellular Respiration Combustion • Input • Sugar + Oxygen • Cellular Respiration • Creates Heat and ATP • Output • CO2 + H2O • Input • Gasoline + Oxygen • Combustion • Creates Heat and movement • Output • CO2 + H2O
Cellular Respiration • A chemical process that uses oxygen to convert the energy in organic molecules into ATP
ATP = Adenosine Triphosphate • ATP = Energy “currency” for cell • ATP provides energy for the cell to do three types of work: • Chemical work= building large molecules • Mechanical work= muscle contraction • Transport work= getting ions across cell membrane
Respiration • Aerobic: A process that requires oxygen • Cellular respiration vs. breathing • Both Bring in Oxygen and release Co2
Cellular Respiration • Video
Cellular Respiration equation • C6H12O6 +6O2 6CO2 + 6H2O + 38ATP
Cellular Respiration • Input: Glucose (C6H12O6) + Oxygen (O2) • Output: Carbon Dioxide (CO2) + Water (H2O) + 38 ATP
Lactic Acid Fermentation • The process used to make ATP without oxygen • Anaerobic= A process that does not require oxygen • ATP is made from just the process of glycolysis • Creates 2 ATP and Lactic Acid
Alcoholic Fermentation • Organisms such as yeast can ferment sugar and other foods but they create ethyl alcohol instead of Lactic Acid • Alcoholic Fermentation also releases CO2 which allows for the rising of bread or carbonation of beverages
