Photosynthesis And Cellular Respiration

Energy and Life Energy is the capacity to do work All living things require energy Cell “work” that requires energy to Grow Reproduce Transport Move

Photosynthesis Photosynthesis: The process that plants and some single-celled organisms use to make glucose (sugar). Photosynthesis occurs in the Chloroplast Takes in CO2 and H2O from the environment Converts sunlight energy into chemical energy in the bonds of glucose

Draw Photosynthesis

Chemical Equation for Photosynthesis Energy from the sun Carbon Dioxide + Water = Glucose + Oxygen ___CO2 + ___H2O  C6H12O6 + ___O2 6 6 6

Chemical Equation for Photosynthesis Energy + Carbon Dioxide + Water = Glucose + Oxygen (From the sun) Products Reactants

Glucose produced by photosynthesis can then be… Used for energy in cellular respiration Glucose is like the plant’s food. It is converted to starch and stored in the plant.

Cellular Respiration Cellular Respiration – the process where the energy stored in the chemical bonds of glucose is converted to energy (ATP). 2 Types: Aerobic (with oxygen) Anaerobic (without oxygen/fermentation)

What is ATP? ATP: Adenosine Triphosphate. Energy source in the cell

Where does cellular respiration occur inside the cell?

The Mitochondria “The Powerhouse of the Cell” “The Mighty Mitochondria”

Chemical Equation for Cellular Respiration Glucose + Oxygen = Carbon Dioxide + Water + Energy 6 6 C6H12O6 + ___O2  ___CO2 + ___H2O + ____ATP 6 36-38

Chemical Equation for Cellular Respiration Glucose + Oxygen = Carbon Dioxide + Water + Energy (ATP) Reactants Products

Card Sort Activity Go to your lab station and sort the cards into the correct equations for Photosynthesis and Cellular Respiration. You may NOT use your notes! Discuss with your group and make your best guess if you are unsure. Raise your hand when finished and I will check them. If your group gets both equations correct on the first try, then you get Bonus Bucks!

Compare the Equations After the card sort, look back at the equations. What did you notice about the Chemical Equations for Photosynthesis and Cellular Respiration?

Compare the Equations After the card sort, look back at the equations. What did you notice about the Chemical Equations for Photosynthesis and Cellular Respiration? The equations are the inverse of each other!
