Light-independent phase of photosynthesis, where carbon dioxide is fixed to a three-carbon compound used to form glucose. ATP and NADH are consumed in this cycle. Also called the Calvin-Benson cycle or the dark reactions.
The biochemical reactions, initiated by Rubisco, that result in the reduction of CO to a carbohydrate (also known as the photosynthetic carbon reduction cycle).
The set of steps in photosynthesis through which carbon dioxide, with energy from ATP and electrons from NADPH, becomes an energetic carbohydrate. This cycle is the stage of photosynthesis where building occurs.
Major metabolic pathway by which CO is fixed during photosynthesis.
The major metabolic pathway that fixes CO2 into carbohydrates during photosynthesis; also called carbon fixation. It is indirectly dependent on light but can occur both in the dark and light. ( Figure 16-49)
a light independent set of reactions occurring in the stroma of the chloroplast that uses NADPH and phosphorous from ATP to produce glucose.
Is also called the light independent or dark reaction of photosynthesis. In the Calvin Cycle, ribulose 5-phosphate, a 5-carbon compound is converted to a 6-carboncompound by the addition of CO2. Through several intermediate steps, this 6 carbon compound is converted to two 3-carbon glyceraldehyde 3-phosphate molecules, which are then converted to glucose. These steps require the addition of hydrogen supplied by NADPH from the light reaction.
(aka Calvin-Benson Cycle or Carbon Fixation) Series of biochemical, enzyme-mediated reactions during which atmospheric carbon dioxide is reduced and incorporated into organic molecules, eventually some of this forms sugars. In eukaryotes, this occurs in the stroma of the chloroplast.
Ribulose bis-phosphate-utilizing biosynthetic cycle of carbon fixation exhibited by C3 autotrophs.
The second of two major stages in photosynthesis (following the light reactions), involving atmospheric CO2 fixation and reduction of the fixed carbon into carbohydrate.
The Calvin cycle (or Calvin-Benson cycle or carbon fixation) is a series of biochemical reactions that takes place in the stroma of chloroplasts in photosynthetic organisms. It was discovered by Melvin Calvin and Andrew Benson at the University of California, Berkeley. James Bassham also made important contributions to elucidating this pathway.
