Cellular Respiration

Energy Energy is the ability to do work Cars running on fuel  Chemical Energy Computers and light bulbs  Electrical Energy

Living organisms depend on energy, too. Sometimes, it is easy to see when we need energy Other times, it is not that obvious

All organisms obtain energy in different ways

Which biomolecule are we mostly dealing with? Lipids Proteins Nucleic Acids Carbohydrates

Carbohydrates Provide quick burst of ENERGY Polymer Monomer Long chain of sugar Monomer Monosaccharide Sugar Glucose

What is cellular respiration? Cellular Respiration is the process where sugars (glucose) are converted into usable energy ATP (Adenosine triphosphate). Glucose is the fuel for Cellular Respiration Cell Respiration happens in the…? MITOCHONDRION

Plant Cells Animal Cells Remember – Chloroplasts are found only in plant cells. Mitochondria are found in both plant and animal cells. Plant Cells Animal Cells

Reactants for Cellular respiration Cellular Respiration needs: Oxygen Fuel/Energy Source Carbohydrates Sugars/Glucose

Products of Cellular Respiration Cellular Respiration will produce: Water Carbon Dioxide Energy/ATP

What is ATP? ATP is a molecule that provides the energy (POWer) to a cell. TED-Ed - Photosynthesis & Food (ATP) BNSG - ATP

General Chemical Reaction Carbon Dioxide Water Glucose (Sugar) Oxygen + Sunlight 6CO2 6H20 C6H12O6 6O2 PHOTOSYNTHESIS C6H12O6 + 6O2 6CO2 + 6H20 + ATP CELLULAR RESPIRATION Glucose (Sugar) Carbon Dioxide Cellular Energy + + Oxygen Water + Waste Products

Photosynthesis and Cellular respiration Carbon Dioxide Water Glucose (Sugar) Oxygen + Sunlight 6CO2 6H20 C6H12O6 6O2 Glucose (Sugar) Oxygen Carbon Dioxide Water + C6H12O6 6O2 6CO2 6H20 ATP Cellular Energy

Analogy A car needs fuel to move A cell needs ATP to function Gasoline provides that energy A cell needs ATP to function ATP is the energy
