Today in biology, we continued to learn about photosynthesis, especially the Calvin Cycle. Named after Melvin Calvin, this cycle helps the process of photosynthesis and is not directly dependent on light. After receiving three carbon molecules from CO2, the carbons are added with rubisco (Ribulose-1,5-bisphosphate carboxylase/oxygenase) to three RuBP molecules. Each RuBP immediately becomes unstable and breaks int two 3-phosphoglycerate molecules. Each of the six 3-phosphoglycerates turns into 1,3-phosphoglycerates after taking one phosphorus from an ATP and turning it into an ADP. Then, 6 protons come in and take a phosphate, leaving 6 G3P's. One leaves to become glucose or another compound. In stage 3, the remaining G3P molecules re-bond with each other and three phosphates from ATP to make 5 RuBPs.
This part is dependent on items produced by the light-dependent reactions. The two are intertwined.
