A botanist brings you a plant that she has collected during her travels and asks you to determine the photosynthetic pathway the plant uses. You grow the plant in a special chamber on a 14:10-hour light/dark cycle and track the fate of radiolabeled CO2 in the plant over 24 hours. You begin monitoring the plant's photosynthetic activity at the beginning of the light portion of the cycle. You find that during the day, the plant's stomata remain closed, and an enzyme with a low affinity for CO2 slowly catalyzes the joining of CO2 and a five-carbon molecule in the plant's mesophyll cells. Once the chamber switches to the night cycle, the plant stomata open, and an enzyme with a high affinity for CO2 slowly catalyzes the joining of CO2 to a three-carbon molecule to produce a four-carbon molecule in the mesophyll cells. What photosynthetic pathway(s) does this plant use? Group of answer choices C4 Photorespiration CAM C3

Photosynthesis

Plants have a capacity that we humans can only imagine— the ability to produce food from sunlight. Sure, we can prepare some dishes that we can savor on, but it become possible because of the plants (as they serve as a producers of all the raw materials required). Photosynthesis is the method of assembling carbohydrates with the aid of sunlight.
