Define photosynthesis. Usually, sites are deactivated at night. What process is catalyzed by Rubisco during light independent reactions? Previous research suggested that Rubisco is likely the most abundant protein on Earth. 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. It constitutes up to 50 percent of all the protein in every plant leaf. Photosynthesis takes the energy of sunlight and combines water and carbon dioxide to produce sugar and oxygen as a waste product.

When we examine the quality of feed in our forages, it is rubisco that makes up most of the protein value in the forage analysis. Answer: Light reactions harness energy from the sun to produce chemical bonds, ATP, and NADPH. The Calvin cycle reactions can be divided into three main stages: carbon fixation, reduction, and regeneration of the starting molecule. Overview of the Calvin cycle. In stage 1, the enzyme RuBisCO incorporates carbon dioxide into an organic molecule. Carbon dioxide is taken in by the plant through small pores called stomata, which are found on the surface of leaves. It acts as a primary carbon dioxide acceptor in the Calvin cycle, and is converted into 2 molecules of 3-PGA (3-phosphoglyceric acid) by the action of RuBisCO. The molecular wt. Heat is supplied from the base surface, whose emissivity is $\varepsilon_{1}=0.8$, at a rate of $800 \mathrm{~W} / \mathrm{m}^{2}$ while the side surfaces, whose emissivities are $0.5$, are maintained at $500 \mathrm{~K}$.
