Photosynthesis and Cellular Respiration What does “ADP” stand for? _________________________________ adenosine diphosphate During photosynthesis, CO2 is used to make glucose in a process called carbon dioxide fixation What is the ultimate source of energy for all plants and animals on Earth? the sun During photosynthesis, what are the 2 inorganic molecules that, along with sunlight, form glucose? CO2 and H2O Photosynthesis or Respiration? - is aerobic respiration What is the name of the pigment found in a majority of plants? chlorophyll Put the following molecules in order based on their energy storing capabilities (from highest to lowest). ADP ATP AMP ATP, ADP, AMP What type of cellular respiration occurs when oxygen is required? aerobic respiration What is the chemical formula for glucose? C6H12O6 Photosynthesis or Respiration? - requires CO2 photosynthesis Specifically, where is the energy stored in an ATP molecule? in the P-bonds Write the chemical equation for cellular respiration. _________________________________ C6H12O6 + 6O2 6CO2 + 6H2O + 38 ATP True or False… Photosynthesis requires oxygen. False What is the pigment that gives leaves, vegetables and some flowers their orange/yellow colors? carotenoids What does “ATP” stand for? _________________________________ adenosine triphosphate What is the name of the process that converts light energy into chemical energy? photosynthesis During photosynthesis, how are the electrons replaced that leave the chlorophyll? water is split When glucose is broken down in the absence of oxygen it is an anaerobic process called fermentation The series of proteins in the thylakoid membrane that carries electrons is called the electron transport chain When water is split during photosynthesis, what 3 products result? electrons, + H, and O2 How many turns of the Calvin cycle are needed to produce 1 glucose molecule? 6 Write the chemical equation for photosynthesis. _________________________________ 6CO2 + 6H2O C6H12O6 + 6O2 Photosynthesis or Respiration? - breaks down glucose respiration Photosynthesis or Respiration? - produces large amounts of ATP respiration Photosynthesis or Respiration? - electron transport chain produces small amounts of ATP and NADPH photosynthesis What is the name of the disk-shaped structures in chloroplasts? (they contain the pigments) thylakoids What are the 2 products of alcoholic fermentation? CO2 and ethyl alcohol (ethanol) When the muscles of the body “run out” of oxygen, what process takes place that allows your muscles to continue to contract? lactic acid fermentation Photosynthesis or Respiration? - carbon dioxide fixation photosynthesis What molecule is the final electron acceptor in the electron transport chain of cellular respiration? oxygen In which organelle does cellular respiration take place? mitochondria Why do leaves turn yellow during the fall? the chlorophyll is broken down and stored in the twigs, allowing the yellow color to show through (it was there all along) Photosynthesis or Respiration? - occurs in all living cells respiration Put the following in order: a. animals eat plants to get energy b. plants absorb sunlight c. plants use chemical energy to make organic compounds d. light from the sun reaches Earth e. plants convert sunlight to chemical energy d b e c a Photosynthesis or Respiration? - light is required photosynthesis What is an organism called that uses sunlight and inorganic molecules to produce organic molecules? autotroph FINAL QUESTION Good Luck! What is the process of splitting water called? photolysis What was the plant that was first used in experiments in the 1700’s that led to the discovery of photosynthesis? The mint leaf
