Explain Why Rubisco Is A Key Component In Photosynthesis

Question 2
a.)
Rubisco is a key component in photosynthesis. It is an enzyme involved in the fixation of atmospheric carbon dioxide.
b.)
Due to global warming, the increased temperature can influence Rubisco which can catalyses oxygenation over carboxylation. During carboxylation CO2 is fixed and raised temperature enhancing oxygenation.
c.)
Level of PGA depends on Rubisco with who is going to bind. Rubisco is an enzyme that reacts with CO2 and O2. The reaction with O2 competes with carboxylation reaction where CO2 is fixed. That means, if Rubisco catalyses with O2, the oxygenase wins, if there is enough CO2 in atmosphere, like at the beginning of evolution then it is the carboxylation reaction.
d.)
Increased oxygenase and reduced carboxylate activity will slow down the photosynthesis. Oxygenation is waste full process because 3-phosphoglycerate is created at reduced rate and higher metabolic cost compared with Rubiscone carboxylase activity.
e.)
They bind together when their identical hydrophobic or the same charged regions are closely revealed to the environment.
Aggregation in vintro can be successfully altered with the help of RbcX chaperone which is able to bind to partly folded large-subunit chain and interact with small subunits. Study by Liu at all. reveals, that aggregation in vintro helped them to obtain 40% of active Rubisco and allowed them to study the effects of mutation in order to get a better enzyme.
Protein aggregation in vintro, does not include the complex of cellular environment, which is very important and crucial in protein aggregation.
