In C4 plants, the first product of CO2 fixation is a 4-carbon compound called oxaloacetate. In CAM plants, the first product of CO2 fixation is converted into malate or another 4-carbon organic acid. These compounds help minimize photorespiration and increase the efficiency of carbon fixation in these plants.
What else can I help you with?
Two alternative photosynthesis pathways found in plants?
C4 and CAM are two alternative photosynthesis pathways found in plants. C4 plants have a specialized mechanism to improve CO2 fixation in hot and dry conditions, while CAM plants use a temporal separation of carbon fixation during the night and day to conserve water.
Where do c4 and cam plants store co2?
C4 plants store CO2 in the mesophyll cells, where initial carbon fixation occurs using PEP carboxylase. CAM plants store CO2 in vacuoles within their cells during the night, when stomata are closed, and use it during the day for photosynthesis when stomata are open.
What type of carbon fixation is least common for plants in arid locations?
The least common type of carbon fixation in plants located in arid environments is C3 photosynthesis. While C3 plants are widespread, they are less efficient in hot and dry conditions due to increased photorespiration and water loss. In contrast, C4 and CAM (Crassulacean Acid Metabolism) pathways have evolved in many arid-adapted plants to minimize water loss and enhance carbon fixation efficiency under stress conditions.
Is prickly peare cactus a c3 or c4 plant?
The prickly pear cactus is a CAM plant, not a C3 or C4 plant. CAM plants use a different carbon fixation pathway called Crassulacean Acid Metabolism that helps them conserve water by opening their stomata at night.
What pathways help plants photosynthesize while minimizing water loss?
Plants use the C4 and CAM pathways to minimize water loss during photosynthesis. These pathways allow plants to efficiently process carbon dioxide while minimizing the opening of stomata, which reduces water loss through transpiration. C4 plants spatially separate carbon fixation and the Calvin cycle, while CAM plants temporally separate these processes.

What biochemical process is responsible for carbon fixation?
The biochemical process responsible for carbon fixation is photosynthesis, specifically the Calvin cycle. During this process, carbon dioxide is converted into carbohydrates by utilizing energy from sunlight and enzymes found in plant cells. This pathway is essential for plants to build organic molecules needed for growth and survival.

Plants that fix CO2 into organic acids at night when the stomata are open and carry out the Calvin cycle during the day when the stomata are closed are called?
Plants that fix CO2 into organic acids at night when the stomata are open and carry out the Calvin cycle during the day when the stomata are closed are called CAM (Crassulacean Acid Metabolism) plants. CAM plants have adapted their carbon fixation process to avoid water loss during the day by keeping stomata closed, and perform photosynthesis during the night when conditions are cooler and less water loss occurs.
What happens during the carbon fixation step of the Calvin cycle?
Products such as G3P or PGAL are produced in the Calvin cycle in C3, C4, and CAM plants. Carbon fixation helps each plant adapt to the particular environment they live in. C4 plants are those such as sugarcane or grasses. CAM plants are the cactus plants or plants that live in the desert. It also helps with the production of ATP.
What type of plants are cam plants?
Cactus
