Weba) The CAM pathway allows more CO2 into the plant but also increases the rate of water loss. b) Both pathways minimize photorespiration but also expend more ATP in the process of carbon fixation. c) Both pathways increase the rate of photosynthesis but also increase the rate of water loss. WebWhy is it difficult for C3 plants to carry out photosynthesis in very hot, dry environments such as deserts? a. The light is too intense and destroys the pigment molecules. b. The closing of stomata keeps CO2 from entering and O2 from leaving the plant. c. They must rely on photorespiration to make ATP. d. CO2 builds up in the leaves, blocking carbon fixation. highlights blonde

C3, C4, and CAM Plants: Adaptations to Climate Change - ThoughtCo

WebCAM plants are known for their capacity to fix carbon dioxide at night, using PEP carboxylase as the primary carboxylating enzyme and the accumulation of malate (which is made by the enzyme malate dehydrogenase) in the large vacuoles of their cells. WebMar 18, 2024 · Rubisco aims to fix carbon dioxide, but can also fix oxygen molecules, which creates a toxic two-carbon compound. Rubisco fixes oxygen about 20 percent of the time, initiating a process called photorespiration that recycles the toxic compound. Photorespiration costs the plant energy it could have used to photosynthesize. WebCAM plants are the plants, which fix carbon dioxide by CAM pathway or Crassulacean acid metabolism. It was first discovered in the plants of the Crassulaceae family. They are … highlights black hair

WebPhotorespiration is a wasteful respiratory process, which hinders the photosynthetic process in many higher plants. The reaction in which carbon dioxide and water combine to give carbohydrates is termed carbon fixation. WebCrassulacean acid metabolism, also known as CAM photosynthesis, is a carbon fixation pathway that evolved in some plants as an adaptation to arid conditions [1] that allows a plant to photosynthesize during the day, but only exchange gases at night.
