What are CAM Plants? Crassulacean Acid Metabolism (CAM) plants are adaptive to the dry environment and include plants like aloe vera and cacti. These plants use CAM photosynthesis to prevent water loss due to transpiration and evaporation.

WebCalvin cycle occurs in all the plants, be it C 3, C 4, CAM or any other plants. It occurs in the stroma of chloroplasts. The first product of carbon dioxide fixation is 3 carbon compound known as 3-phosphoglyceric acid or PGA. CO 2 acceptor is a 5 carbon compound … WebC 4 fixation is an addition to the ancestral and more common C 3 carbon fixation. The main carboxylating enzyme in C 3 photosynthesis is called RuBisCO, which catalyses two distinct reactions using either CO 2 (carboxylation) or oxygen (oxygenation) as a substrate.
