Final answer:
The statement about photorespiration is false; photorespiration is a wasteful process contrasting with photosynthesis and cellular respiration, which build and break down carbohydrates, respectively, capturing energy necessary for life.
Step-by-step explanation:
The statement that photorespiration is the process by which light is used to release the stored energy in carbohydrate molecules to perform all work in plant cells is false. Photorespiration is actually a process that occurs in plants when the enzyme Rubisco oxygenates RuBP, leading to a wasteful pathway as opposed to the Calvin cycle. In contrast, photosynthesis utilizes light energy to build carbohydrates, and cellular respiration is the process where the energy stored in carbohydrates is released by cells to perform work. Both photosynthesis and cellular respiration use electron transport chains to capture the energy necessary to drive other reactions, allowing organisms to access life-sustaining energy.
