The Calvin cycle of photosynthesis begins after light energy is transformed into chemical energy by the cells of plants. The adenosine triphosphate, or ATP, molecules created power the Calvin cycle. The Calvin cycle uses the energy to create carbohydrates from water and carbon dioxide.Know More
The Calvin cycle is the main way the energy created during photosynthesis is used. The carbohydrates it generates are both the main energy storage molecules and the main structural components of plants. The Calvin cycle only creates simple sugars by itself, but more complex carbohydrates such as starches and cellulose are constructed from those simple sugars in other processes.
Photosynthesis takes place in the chloroplasts, special organelles in plant cells and algae. To use the light energy from the sun, the chloroplasts have molecules known as chlorophyll. These molecules are large protein structures with a magnesium atom in the middle. The light energy causes the magnesium atoms to release electrons, which then power the creation of ATP. Not all the reactions are direct. Other molecules like beta carotene can absorb light energy and pass the energy to the chlorophyll molecule. These other molecules absorb different colors of light than chlorophyll, so they help the plant cells be more efficient.Learn more in Optics & Waves
The final product of the Calvin cycle, the second metabolic cycle of photosynthesis, is the sugar glucose. Carbon dioxide joins with organic molecules to produce glyceraldehyde-3-phosphate. After several glyceraldehyde-3-phosphates are produced from the cycle, they join together to form glucose.Full Answer >
The Calvin cycle is a metabolic process that occurs in the chloroplasts of plant cells. Its main function is to create sugar from carbon dioxide for the plant to use as a source of energy.Full Answer >
The Calvin cycle is a metabolic pathway that is found in the stroma of the chloroplast. Carbon enters the pathway in the form of CO2 and exits in the form of sugar.Full Answer >
The reactants in the Calvin cycle are carbon dioxide, water and a sugar with five carbon atoms known as ribulose. The enzyme catalyst RuBisCo and energy donators aAdenosine triphosphate, or ATP, and nicotinamide adenine dinucleotide phosphate, or NADPH, are necessary for the reaction but aren't reactants in the technical sense.Full Answer >
