What is the process of converting carbon dioxide into sugars?
After carbon dioxide enters the leaf through stomata it moves into the mesophyll cells where photosynthesis occurs and glucose is constructed. Photosynthesis is the process by which plants use light energy to convert carbon dioxide and water into sugars.
Is a process that converts sugar and oxygen to carbon dioxide water and energy?
Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body’s cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.
What process makes sugar out of carbon dioxide and water?
How is CO2 used in the Calvin cycle?
In the Calvin cycle, carbon atoms from CO2start text, C, O, end text, start subscript, 2, end subscript are fixed (incorporated into organic molecules) and used to build three-carbon sugars. This process is fueled by, and dependent on, ATP and NADPH from the light reactions.
What occurs in Calvin cycle?
The Calvin cycle is part of photosynthesis, which occurs in two stages. In the first stage, chemical reactions use energy from light to produce ATP and NADPH. In the second stage (Calvin cycle or dark reactions), carbon dioxide and water are converted into organic molecules, such as glucose
What is G3P used for?
Glyceraldehyde 3-phosphate or G3P is the product of the Calvin cycle. It is a 3-carbon sugar that is the starting point for the synthesis of other carbohydrates. Some of this G3P is used to regenerate the RuBP to continue the cycle, but some is available for molecular synthesis and is used to make fructose diphosphate.
What happens during carbon fixation quizlet?
What happens during the CARBON FIXATION phase of the Calvin Cycle? Carbon from CO2 is added to a 5-carbon molecule (ribulose-1,5- bisphosphate or RuBP). So it can fix more carbon from CO2. Energy from ATP is used to rebuild RuBP.
What happens during the carbon fixation stage of Calvin cycle?
In fixation, the first stage of the Calvin cycle, light-independent reactions are initiated; CO2 is fixed from an inorganic to an organic molecule. In the second stage, ATP and NADPH are used to reduce 3-PGA into G3P; then ATP and NADPH are converted to ADP and NADP+, respectively
What is carbon fixation and how does it relate to photosynthesis quizlet?
What is carbon fixation, and how does it relate to photosynthesis? It is the conversion of CO2 into organic compounds, and it forms 3-PGA. The L-D reactions require light energy and water, and the L-IND reactions require ATP, NADPH and CO2.
Which compound is produced during carbon fixation?
Which compound is produced during carbon fixation quizlet?
In the Calvin cycle, carbon dioxide is incorporated into organic compounds, a process called carbon fixation. The Calvin cycle produces a compound called G3P. Most G3P molecules are converted into RuBP to keep the Calvin Cycle operating.
Where does the carbon that is used in photosynthesis come from?
The carbon that plants need for photosynthesis comes from carbon dioxide, or CO2 that’s present in our atmosphere.
