What Is the Calvin Cycle? What happens during the Calvin cycle? The Calvin cycle occurs in three phases. During the first phase, carbon fixation, carbon dioxide enters the cycle. An enzyme called RuBP carboxylase fixes carbon into ribulose biphosphate, which is a five-carbon sugar abbreviated as RuBP.

Sugar Biopolymers of sugars are common in nature. Through photosynthesis, plants produce glyceraldehyde-3-phosphate (G3P), a phosphated 3-carbon sugar that is used by the cell to make monosaccharides such as glucose (C 6H 12O 6) or (as in cane and beet) sucrose (C 12H 22O 11).

Critical Thinking Questions The products of the light dependent reaction are used to power the Calvin cycle to produce glucose. When photons strike photosystem (PS) II, pigments pass the light energy to chlorophyll molecules that in turn excite electrons, which are then passed to the electron transport chain.

How does the Calvin cycle make sugar? Answered by The Community. Making the world better, one answer at a time. Using Carbon from CO2, energy from ATP, and high-energy electrons from NADPH, the Calvin Cycle constructs an energy-rich sugar molecule called glyceraldehyde 3 phosphate (G3P). The plant cell can then use G3P as the raw material to make the glucose and other organic compounds that it needs.

- A: The Calvin cycle uses adenosine triphosphate , or ATP, as energy and consumes NADPH2 as a reducing power in the production of sugar in a plant cell. The Calvin cycle takes place in the stroma of the chloroplast. ATP and NADPH2 are part of phase two of the Calvin cycle.

Calvin cycle At this stage of photosynthesis, the energy released from ATP produced during light reactions is used to drive the conversion of carbon dioxide and other compounds into an organic molecule (e.g. glucose). In C3 plants, the Calvin cycle is used directly to fix carbon dioxide. In C4 plants and CAM plants, a different carbon fixation precedes Calvin cycle. Word origin: named after one of the discoverers, Melvin Calvin, a Nobel prize-winning chemist. See also: Photosynthesis on Tutorials for further information.

BIOLOGY question? The net effect of these steps is to convert light energy into chemical energy in the form of ATP and NADPH. The ATP and NADPH from the light-dependent reactions are used to make sugars in the next stage of photosynthesis, the Calvin cycle. In another form of the light reactions, called cyclic photophosphorylation, electrons follow a different, circular path and only ATP (no NADPH) is produced.
