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 about Optics & Waves
The types of light energy available include visible light energy, infrared light energy, ultraviolet energy, electromagnetic energy and X-ray energy. The different types of energy are used by human beings in order to achieve certain objectives that make life much easier.Full Answer >
The enzymatic reactions of the Calvin cycle take place within the stroma of the chloroplast during photosynthesis. Although the Calvin cycle is sometimes also referred to as a dark reaction, this is a little misleading because the Calvin cycle indirectly relies on light. The cycle is named after Melvin Calvin, the scientist who discovered the reaction.Full Answer >
The Calvin cycle is a metabolic process that uses the carbon from carbon dioxide, along with energy in the form of ATP, to produce sugar. This cycle takes place in the stroma of chloroplasts, which are found in plant cells.Full Answer >
Chlorophyll is a pigment found in the chloroplasts of plants that absorbs the wavelengths of light required to convert water and carbon dioxide into chemical energy during photosynthesis. Molecules of chlorophyll are arranged around the photosystems embedded in the chloroplasts' thylakoid membranes. There can be several hundred chlorophyll molecules per photosystem.Full Answer >
