Question 16 (1 point) Below are the word equations for two important biochemical reactions. Photosynthesis: carbon dicxide+water+energy-sugar+oxygen Cellular Respiration: sugar+oxygen-carbondioxide+water+energy What can you conclude from these word equations? Photosynthesis is an endothermic reaction and cellular respiration is an exothermic reaction Photosynthesis is an exothermic reaction, and cellular respiration is an endothermic reaction Both photosynthesis and cellular respiration are exothermic reactions Both photosynthesis and celiular respiration are endothermic reactions
