CAM Pathway
The CAM pathway is a unique mechanism for carbon fixation in plants that allows them to carry out photosynthesis in arid environments with minimal water loss. By fixing carbon dioxide at night and storing it as malic acid, CAM plants are able to use it during the day to carry out photosynthesis without losing water.…
