Question

In succulent xerophytes, there is accumulation of malic acid in night, this path ofC{{O}_{2}}
metabolism is called
A) Beta carboxylation
B) Hatch and Slack cycle
C) Crassulacean acid metabolism
D) Calvin cycle

Answer 1

In succulent xerophytes, there is accumulation of malic acid in night, this path ofC{{O}_{2}}
metabolism is called
A) Beta carboxylation

Answer 2

In succulent xerophytes, there is an accumulation of malic acid at night:

C) Crassulacean acid metabolism.

• CAM plants are dominant in very hot, dry environments like deserts like Sahara, so thriving in very wet soil would not be an advantage for them.

• Crassulacean acid metabolism Pathway is another Calvin cycle modification made by succulents and other plants growing in areas of high temperatures like deserts.

• CAM pathways have evolved independently over two dozen times and may give plant species in hot climates a significant evolutionary upper hand.
