With the help of the enzyme RuBisCo this reaction takes place.
CO2 + ribulose biphosphate ( a 5 C sugar ) -> 2(3-phosphoglycerate)( 3 C sugar)
This happens in the Calvin cycle. With CO2 and RuBP a reaction takes place with ATP and NADPH to do a complicated bit of arranging with the three CO2's coming into the cycle. Six of the 3-phosphogylcerates are made, but only one the product of one cycle and the rest go back into the cycle. The 3 carbon sugar then can be used to build glucose or used in the mitochondria for energy.
What else can I help you with?
Where do plants get the carbon they use to make organic molecules?
Plants get the carbon they use to make organic molecules from carbon dioxide in the air through the process of photosynthesis. During photosynthesis, plants use sunlight to convert carbon dioxide into glucose and other organic compounds, which they use as building blocks for growth and energy.
In the light independent reactions carbon dioxide becomes fixed to?
In the light independent reactions, carbon dioxide becomes fixed to ribulose-1,5-bisphosphate (RuBP) with the help of the enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) to form 3-phosphoglycerate in a process known as carbon fixation.
How does the process of photosynthesis affect carbon dioxide concentrations in the atmosphere during a typical year?
Photosynthesis uses carbon dioxide as a raw material where carbon dioxide is fixed into organic molecules. This process lowers the level of carbon dioxide in the atmosphere. The seasonal fluctuation of carbon dioxide levels during a year may be caused by increased photosynthesis during spring and summer.
What goes into the Calvin cycle ( photosynthesis)?
The Calvin cycle, which is part of the light-independent reactions of photosynthesis, starts with carbon dioxide from the atmosphere being fixed by the enzyme Rubisco. This fixation process leads to the production of intermediate molecules such as 3-phosphoglycerate and eventually results in the formation of glucose. The cycle also requires energy in the form of ATP and NADPH, which are produced during the light-dependent reactions of photosynthesis.
In C4 and CAM plants carbon dioxide is fixed in the of mesophyll cells?
In C4 plants, carbon dioxide is initially fixed in the mesophyll cells by the enzyme PEP carboxylase, forming a 4-carbon compound before being transferred to bundle sheath cells. In CAM plants, carbon dioxide is fixed in the mesophyll cells at night and stored as organic acids until daylight when it is released and used in the Calvin cycle.
How do you describe the carbon cycle?
The two processes of the carbon cycle are photosynthesis and cellular respiration. In photosynthesis carbon from carbon dioxide is fixed into carbohydrates. In cellular respiration, carbohydrates are broken down to form ATP and carbon in the form of carbon dioxide is released into the atmosphere.
How is photosynthetically fixed carbon lost by photorespiration?
Photosynthetically fixed carbon is lost through photorespiration when the enzyme RuBisCO catalyzes the reaction of ribulose bisphosphate (RuBP) with oxygen instead of carbon dioxide. This process leads to the production of a two-carbon compound that is subsequently converted into carbon dioxide, resulting in a net loss of fixed carbon. Photorespiration is more likely to occur under conditions of high oxygen concentration and low carbon dioxide concentration, ultimately reducing the efficiency of photosynthesis. As a consequence, plants may experience decreased growth and productivity, especially in hot, arid environments.
Does the Calvin cycle fix carbon dioxide?
Yes, the Calvin cycle is the process by which carbon dioxide is fixed into organic molecules during photosynthesis. The enzyme RuBisCO helps catalyze the fixation of carbon dioxide into ribulose-1,5-bisphosphate, leading to the production of carbohydrates.
The carbon to produce carbohydrates in the second stage of photosynthesis comes from?
The carbon to produce carbohydrates in the second stage of photosynthesis comes from carbon dioxide in the atmosphere. During the Calvin cycle, carbon dioxide is fixed and converted into glucose molecules that make up carbohydrates.
What molecule does carbon dioxide end up getting fixed into?
Carbon dioxide is fixed into a three-carbon molecule called 3-phosphoglycerate (3-PGA) during the Calvin cycle of photosynthesis. This process occurs in the chloroplasts of plant cells, where CO2 is combined with ribulose bisphosphate (RuBP) through the action of the enzyme ribulose bisphosphate carboxylase/oxygenase (RuBisCO). This initial fixation is a crucial step in converting inorganic carbon into organic compounds that can be used by the plant for energy and growth.
Where do plants get the carbon they use to make organic molecules?
Plants get the carbon they use to make organic molecules from carbon dioxide in the air through the process of photosynthesis. During photosynthesis, plants use sunlight to convert carbon dioxide into glucose and other organic compounds, which they use as building blocks for growth and energy.
What two biological processes drive the carbon cycle?
The two processes of the carbon cycle are photosynthesis and cellular respiration. In photosynthesis carbon from carbon dioxide is fixed into carbohydrates. In cellular respiration, carbohydrates are broken down to form ATP and carbon in the form of carbon dioxide is released into the atmosphere. The two processes of the carbon cycle are photosynthesis and cellular respiration. In photosynthesis carbon from carbon dioxide is fixed into carbohydrates.

Carbon atoms are fixed into organic compounds in?
Carbon atoms are fixed into organic compounds in the process of photosynthesis, which occurs in plants and other photosynthetic organisms. During photosynthesis, carbon dioxide from the atmosphere is converted into organic molecules such as glucose with the help of sunlight and chlorophyll. This carbon fixation is essential for the production of carbohydrates and other organic molecules that serve as energy sources for living organisms.
Transfer of carbon between organisms depends primarily on what?
Transfer of carbon between organisms depends primarily on the process of photosynthesis, where plants use carbon dioxide to produce food. This fixed carbon is then transferred to consumers through consumption or feeding relationships in ecosystems. Decomposers also play a crucial role in recycling carbon by breaking down organic matter.
What purpose does carbon dioxide serve in photosynthesis?
Carbon dioxide serves as the source of carbon atoms that are fixed during the Calvin cycle of photosynthesis. These carbon atoms are used to build sugars and other organic molecules essential for plant growth and metabolism. Without carbon dioxide, plants would not be able to produce these vital compounds through photosynthesis.
In the light independent reactions carbon dioxide becomes fixed to?
In the light independent reactions, carbon dioxide becomes fixed to ribulose-1,5-bisphosphate (RuBP) with the help of the enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) to form 3-phosphoglycerate in a process known as carbon fixation.
In which natural cycle must an important gas in earth's atmosphere be fixed?
The important gas in Earth's atmosphere that must be fixed is carbon dioxide (CO2). It is fixed through the process of photosynthesis in plants and phytoplankton, where they absorb CO2 from the atmosphere and convert it into organic carbon compounds. This process plays a crucial role in the carbon cycle, helping to regulate the amount of CO2 in the atmosphere.
