RuBisCO is an enzyme whose function can be related to the state of the stomata. When the stomata are open and photosynthesis is active, RuBisCO ribulose bisphosphate.
RuBisCO carboxylates the ribulose bisphosphate (RuBP) as the RuBP accepts 3 molecules of carbon dioxide and form 2 molecules of 3-phosphoglycerate during photosynthesis. It occurs during the Calvin cycle and it is also called as C3 cycle as the first molecule is a 3 carbon molecule.
Please give a thumbs up if the answer helped you. Thank you! :)

How are the functions of stomata and guard cells related and what would be the consequence if those cells did not function property? Select one: a. Guard cells are responsible for opening and closing the stomata, and if the stomata did not function then gas exchange and transpiration will not occur through these cells b. Guard cells are responsible for opening and closing of the stomata, and if the guard cells did not function then gas exchange and transpiration will...
True/false, if false explain why Rubisco Activase can catalyze removal of a sugar from Rubisco's active site when Rubisco Activase's disulfide bridge is oxidized.
5. Photosynthetic adaptations to extreme environments Aa Aa Rubisco carries out photorespiration when the ratio of O2 to CO2 is too high. As a result, certain plants have adaptations meant to keep this ratio low in tissue locations where their photosynthetic cells need to use Rubisco. The following image describes how when these two sets of events occu plants prevent photorespiration. Label the image by identifying where or C3 Carbohydrate M Sunlight ATP HANN and and C-c-c- NADPH GGGG NADPH...
7. Explain the basics of enzyme function and structure (sketch an enzyme and label the active site, allosteric site, where the substrate binds, where competitive and non-competitive inhibitors bind). Include how many different reactions can be catalyzed by an enzyme and how many times an enzyme can catalyze that reaction.
Explain the function of the enzyme whose deficiency results in methylmalonic acidemia and how that relates to lipid and amino acid metabolism.
An extremely important process is called "CARBON FIXATION' What is carbon fixation? This is where plants incorporate CO_2 into organic compounds-the base of our food web This is where plants strip electrons from organic food molecules This is the stage in photosynthesis where glucose appears This is the stage in Calvin cycle where ribulose bisphosphate is regenerated, ready for a new cycle This is where photosynthetic species are eaten, moving their energy into the food web Plants couple tow photosystems...
Vmax of an enzyme-catalyzed reaction is A. the rate observed when the enzyme active sites are saturated with substrate B. independent of the amount of enzyme present C. the rate observed at the highest substrate concentration that can be experimentally obtained D. the initial rate observed at very low substrate concentrations
4. Every enzyme has an optimal pH at which they function, which can vary widely for many different proteins. Some enzymes function best at low pH while others function best at high pH. Provide an explanation as to why this is and include in your answer a discussion of protonation states (specifically within the active sites). (2pts)
We have just enough time to get our bearings when we see a huge enzyme (called hexokinase) closing in. We are wrapped into the active site of the enzyme. Your classmate sitting on Carbon #6 is brutally launched as the enzyme removes a phosphoryl group from ATP and attaches it to the carbon. We are released from the enzyme and the molecule on which we ride is now Glucose-6-phosphate. What is this type of active site binding called? What type...
Please explain. Which statement is true? A state function is one whose value for a system is determined by the temperature of the system, and not on the composition of the system. A state function is one whose value for a system depends on the method of preparation of the reactants and products. A state function is one whose value for the system is determined by only the pressure of the system, and not on the temperature of the system....
