The Calvin cycle is part of photosynthesis, which occurs in two stages. In the first stage, chemical reactions use energy from light to produce ATP and NADPH. In the second stage (Calvin cycle or dark reactions), carbon dioxide and water are converted into organic molecules, such as glucose. Although the Calvin cycle may be called the "dark reactions," these reactions don't actually occur in the dark or during nighttime. The reactions require reduced NADP, which comes from a light-dependent reaction. The Calvin cycle consists of:
Carbon fixation - Carbon dioxide (CO2) is reacted to produce glyceraldehyde 3-phosphate (G3P). The enzyme RuBisCO catalyzes the carboxylation of a 5-carbon compound to make a 6-carbon compound that splits in half to form two 3-phosphoglycerate (3-PGA) molecules. The enzyme phosphoglycerate kinase catalyzes phosphorylation of 3-PGA to form 1,3-biphosphoglycerate (1,3BPGA).
Reduction reactions - The enzyme glyceraldehyde 3-phosphate dehydrogenase catalyzes reduction of 1,3BPGA by NADPH.
Ribulose 1,5-bisphosphate (RuBP) regeneration - At the end of the regeneration, the net gain of the set of reactions is one G3P molecule per 3 carbon dioxide molecules.
Calvin Cycle Chemical Equation
The overall chemical equation for the Calvin cycle is:
3 CO2 + 6 NADPH + 5 H2O + 9 ATP → glyceraldehyde-3-phosphate (G3P) + 2 H+ + 6 NADP+ + 9 ADP + 8 Pi (Pi = inorganic phosphate)
Six runs of the cycle are required to produce one glucose molecule. Surplus G3P produced by the reactions can be used to form a variety of carbohydrates, depending on the needs of the plant.
The Green Algae has stem and has its color green. So it has the Chlrorophyll, the green pigment that makes it green. The same with the plant Caulerpa. Caulerpa has its distinctive stem and leaves. Caulerpa plant is also color green due to its green pigment that is being produce by Chlorophyll. But Mushrooms do not have the same color green. So, it has no that called green pigment that makes a plant color green. The common thing with these plants are the stem-like part/s. And also, these three types of plant have spores. Especially this mushroom, spore-type of plant. So, the answer must be letter B. 2 and 3 (2-Stem-like parts & 3-Spores).
