Question

describe in brief photosynthetic pathway in crassulaceae family ​

Answer 1

Answer:

Such plants demonstrate the course of the metabolism of crassulacean acid (CAM), first discovered in the Crassulaceae plant family. PEPcase and rubisco are found in the photosynthetic tissue of these plants. There was  a mistake.

Rubisco has a lower CO2 affinity than PEPCase activated with light.

Answer 2

Explanation:

Crassulacean acid metabolism, also known as CAM photosynthesis, is a carbon fixation pathway that evolved in some plants as an adaptation to arid conditions.[1] In a plant using full CAM, the stomata in the leaves remain shut during the day to reduce evapotranspiration, but open at night to collect carbon dioxide (CO

2), and allow it to diffuse into the mesophyll cells. The CO

2 is stored as the four-carbon acid ma

late in vacuoles at night, and then in the daytime, the malate is transported to chloroplasts where it is converted back to CO

2, which is then used during photosynthesis. The pre-collected CO

2 is concentrated around the enzyme RuBisCO, increasing photosynthetic efficiency. The mechanism was first discovered in plants of the family Crassulaceae
