True 3. Microorganisms classified as Plantae obtain most of their energy by converting energy into energy. Light (sunlight); chemical (sugars) 1. Define catabolism. Catabolism is the process of breaking down larger molecules into useful energy sources. 2. Upon cellular injury, which metabolic process is involved during the growth and repair phases of the cell? The anabolic process would be active as it (by definition) is involved in the building up of small complexes into larger complexes. 1. In phosphorylation, the light reactions always occur where? The process of converting light energy into chemical energy (photophosphorylation) always occurs in the membrane. 2. True or False: The Calvin cycle must occur in the absence of light. False. The term ‘dark reactions’ (also known as the Calvin Cycle) simply denotes the second stage in photosynthesis—dark reactions do not actually require darkness in order to occur.
