RuBisCO is important biologically because it catalyzes the primary chemical reaction by which inorganic carbon enters the biosphere. Phosphoenolpyruvate carboxylase, unlike RuBisCO, only temporarily fixes carbon.
Q. What do the G3Ps turn into?
A G3P molecule contains three fixed carbon atoms, so it takes two G3Ps to build a six-carbon glucose molecule. It would take six turns of the cycle, or 6 CO2start text, C, O, end text, start subscript, 2, end subscript, 18 ATP, and 12 NADPH, to produce one molecule of glucose.

Q. What happens if RuBisCO is not present?
If Rubisco or an enzyme like Rubisco never existed, there would be no exchange of gases so organisms would not have evolved and we would not exist. Without plants, and their dependency on Rubisco, this cycle of carbon would be even more skewed. Enzymes allow chemical reactions to take place at a greater rate.
Q. How quickly does Rubisco work?
In spite of its central role, rubisco is remarkably inefficient. As enzymes go, it is painfully slow. Typical enzymes can process a thousand molecules per second, but rubisco fixes only about three carbon dioxide molecules per second. Plant cells compensate for this slow rate by building lots of the enzyme.
Q. What is the most important enzyme?
The world’s most abundant and most important enzyme is RuBisCo. It’s the most abundant because it’s present in relatively large quantities in every photosynthetic organism on the planet – from microscopic cyanobacteria and phytoplankton in the oceans to the leaves of giant-sized trees in the tropics.
Q. Will digestive enzymes help with gas?
This enzyme helps reduce gas and bloating caused by eating beans and cruciferous vegetables (like broccoli and cabbage). It does this by breaking down some of the oligosaccharides found in these foods. So if you have IBS and are get gassy after eating beans and certain veggies, this specific digestive enzyme may help.
Q. Do digestive enzymes make you sleepy?
Well, as we’re digesting our meal, more of our blood is shunted to the stomach and gut, to transport away the absorbed newly digested metabolites. This leaves less blood for the rest of the body and can cause some people to feel a bit “light-headed” or tired.
Q. Can digestive enzymes help to lose weight?
While digestive enzyme supplements may or may not directly boost weight loss, they could promote healthy digestion and regularity, especially for those with certain gastrointestinal conditions. Noom helps you adopt healthy habits so you can lose weight and keep it off.
