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.
The Calvin cycle is known as the dark reaction because it is the metabolic cycle of photosynthesis that does not require light. During the Calvin cycle carbon dioxide from the air is added to an organic molecule, RuBP, which is already present in the cell. RuBP becomes unstable and splits into two three-carbon chains known as 3-phosphoglycerate. The two molecules move through a series of reactions using the energies ATP and NADPH, which are produced from the light reactions of photosynthesis. Finally, the 3-phosphoglycerates are converted into two molecules of glyceraldehyde-3-phosphate. Then, some of the glcyeraldehyde-3-phosphates join together to form glucose. Several cycles of the Calvin cycle are required to produce one glucose chain because only one carbon atom is added to the chain from each molecule of carbon dioxide. However, once the glucose chain is formed, it is usually released to the plant to serve as energy for building new cells. Some of the glucose remains in the Calvin cycle to help facilitate the process.Learn More
Skin mitosis is the process by which skin cells divide, creating new skin cells for wound repair and skin renewal. Unlike in other types of cells, mitosis occurs constantly in healthy skin cells, according to NCBI.Full Answer >
As explained by DevBio, nondisjunction is what happens when a pair of chromosomes do not separate properly during meiosis. According to Indiana University-Purdue University Indianapolis (IUPUI), nondisjunction can occur during either anaphase I or anaphase II of meiosis.Full Answer >
As BBC explains, the main purpose of microvilli is to increase the surface area of the small intestine. With larger surface area, nutrients from food are more readily absorbed into the blood.Full Answer >
The mitochondria inside a cell produces ATP, or adenosine triphosphate. Cellular respiration is responsible for ATP production, a process in which ATP production occurs after biochemical energy from nutrients is converted.Full Answer >
