Ribulose

D-erythro-pentulose; d-adonose; d-erythro-2-ketopentose;the 2-keto isomer of ribose. As the 5-phosphate, it participates in the pentose monophosphate shunt; as the 1,5-bisphosphate, it combines with co2 at the start of the photosynthetic process in green plants (carbon dioxide trap); d-ribulose is the epimer of d-xylulose.

C3, C4, and CAM

There are many differance between 3 kinds. But U can look up about the RIBULOSE (enzime) and the way how thet can keep CO2 in air! Hope u succeed.

photosynthesis

... producet in photophosphorylation and it is required to reduce phosphoglyceric acid (PGA) to phosphoglyceraldehyde (PGAL) and then to reconstruct ribulose bisphosphate (RuBP) - NAD is used in respiration as hydrogen carrier - NADH2 is the reduced form of NAD - co-enzymes - NAD, FAD and cytochrome; ...

Cellular respiration in sperm cells.

... of glycerate 3-phosphate (GP, but also known as 3-phosphoglycerate (PGA)) are produced by the first step of the light-independent reactions when ribulose 1,5-bisphosphate (RuBP) and carbon dioxide are catalysed by the rubisco enzyme. The GP is converted to PGAL using the energy in ATP and the ...

TO ANYBODY THAT HAS ANYQUESTIONS ON PHOTOSYNTHESIS

... leaf. The Calvin Cycle occurs in the stroma of chloroplasts (where would it occur in a prokaryote?). Carbon dioxide is captured by the chemical ribulose biphosphate (RuBP). RuBP is a 5-C chemical. Six molecules of carbon dioxide enter the Calvin Cycle, eventually producing one molecule of glucose. ...
