What does the calvin cycle use to produce high-energy sugars? It uses ATP and NADPH to produce high-energy sugars. Why are the reactions of the Calvin cycle also called the light independant reactions?
Why does it take three turns of the Calvin cycle to produce G3P, the initial product of photosynthesis? Because G3P has three carbon atoms, and each turn of the cycle takes in one carbon atom in the form of carbon dioxide.
How does ATP synthase obtain the energy to produce ATP? Hydrogen ions flow down a concentration gradient from the thylakoid space to the stroma through ATP synthase, releasing energy that can be used to produce ATP from ADP + Pi. … Another three molecules of ATP are then used in the cycle.
The overall purpose of the light-dependent reactions is to convert light energy into chemical energy. This chemical energy will be used by the Calvin cycle to fuel the assembly of sugar molecules. … To replace the electron in the chlorophyll, a molecule of water is split.
In the Calvin cycle, carbon dioxide is incorporated into organic compounds, a process called carbon fixation. … In the light reactions, energy is absorbed from sunlight and converted into a chemical energy; in the Calvin cycle, carbon dioxide and chemical energy are used to form organic compounds.
Summary. The primary function of the Calvin cycle is carbon fixation, which is making simple sugars from carbon dioxide and water.
Overview of the Calvin cycle This process is fueled by, and dependent on, ATP and NADPH from the light reactions. Unlike the light reactions, which take place in the thylakoid membrane, the reactions of the Calvin cycle take place in the stroma (the inner space of chloroplasts).
What is the Calvin cycle and where does it take place? The Calvin Cycle occurs in the stroma of a chloroplast in a plant cell. The stroma is the colorless fluid that surrounds the grana of the chloroplast, where the first step of photosynthesis takes place.
The Calvin cycle occurs in the stroma. The light reactions of photosynthesis use _____ and produce _____.
The product of the Calvin cycle is a triose-phosphate sugar that is either exported from the chloroplast or used to regenerate RUBP.
makes sugar. starting compound called RuBP, each turn of the Calvin cycle, there are chemical inputs and outputs.
The Calvin cycle reactions use chemical energy from NADPH and ATP that were produced in the light reactions.
Light reactions harness energy from the sun to produce chemical bonds, ATP, and NADPH. These energy-carrying molecules are made in the stroma where carbon fixation takes place.
As electrons move through the electron transport chain, they go from a higher to a lower energy level and are ultimately passed to oxygen (forming water). Energy released in the electron transport chain is captured as a proton gradient, which powers production of ATP by a membrane protein called ATP synthase.
