3.3 Compare and contrast photosynthesis and respiration in terms of energy
Reactants—what goes in to a chemical reaction or what is on the left side of the arrow in a chemical equation. • Products—what comes out of a chemical reaction or what is on the right side of the arrow in a chemical equation.
Photosynthesis equation 6CO2 + 6H2O sunlight C6H12O6 + 6O2 carbon dioxide + water sunlight glucose (sugar) + oxygen Reactants Products The arrow means “yields,” which is the same as produces or an equals sign in a math problem. Sunlight is written above the arrow to show that it has to be present for the reaction to occur.
Photosynthesis songto the tune of Happy Birthday Six CO2 plus six H2O In the presence of sunlight yields C6H12O6 plus 6O2 Which means….. Carbon dioxide plus water In the presence of sunlight yields Glucose, which is a sugar, plus oxygen Which means… Reactants are carbon dioxide and water Products are glucose and oxygen Reactants go in And products come out
Steps of photosynthesis • Light-dependent reactions—produce oxygen and covert ADP and NADP+ into the energy carriers ATP and NADPH • Calvin Cycle or Light independent reactions—uses the ATP and NADPH from the light-dependent reactions to produce high energy sugars
Respiration equation C6H12O6 + 6O2 6CO2 + 6H2O + energy glucose (sugar) + oxygen carbon dioxide + water + energy Reactants Products
Respiration Songto the tune of Row, Row, Row Your Boat Respiration is the opposite of photosynthesis The reactants are now the products and Energy’s at the end
