Page 92 Essential Question: How does energy flow through the processes of Photosynthesis and Cellular Respiration? ATP- Adenosine TriPhosphate Most important moleculesupplies energy to the cell 3 Parts 1. Adenosine 2. Sugar- Ribose 3. Three Phosphates Energy and Bonds Break Phosphate bonds Energy is released- ADP Create Phosphate bond Energy is needed Store energy as ATP ATP ADP + P + ENERGY Photosynthesis ENERGY GOAL: convert solar energy to chemical energy (MAKE FOOD FOR PLANTS) Equation: 6CO 2 + 6H 2 O C 6 H 12 O 6 + 6O 2 2 STEPS: 1. Light-Dependent Reaction- REQUIRES sunlight -USES SUNLIGHT to change WATER into OXYGEN and ATP 2. Light-Independent Reaction (Dark Reaction and Calvin Cycle) DOESN T REQUIRE sunlight USES ATP to change CARBON DIOXIDE into glucose (sugar) Cellular Respiration GOAL: convert chemical energy (glucose) into stored energy (ATP). Equation: C 6 H 12 O 6 + 6O 2 6CO 2 + 6H 2 O + ATP STEP 1: GLYCOLYSIS -USES ENZYMES break down glucose into pyruvic acid/pyruvate and ATP STEP 2: DEPENDS ON OXYGEN!!!! Aerobic Respiration- OXYGEN PRESENT 1. Citric Acid/Krebs Cycle USES Pyruvic acid (from glycolysis) produces carbon dioxide and ATP (energy) 2. Electron Transport Chain USES oxygen to produce water and LOTS of ATP!!! Anaerobic Respiration- NO OXYGEN PRESENT 1. Lactic Acid USES pyruvic acid to create lactic acid and some ATP 2. Alcohol Fermentation USES pyruvic acid to create alcohol, carbon dioxide and some ATP
