In eukaryotic cells, or cells with a nucleus, the stages of the cell cycle are divided into two major phases: interphase and the mitotic (M) phase. Where ever input thresholds (or boundaries) require significant changes in output modeling, you will find piece-wise functions. In your day to day life, a piece wise function might be found at the local car wash: $5 for a compact, $7.50 for a midsize sedan, $10 for an SUV, $20 for a Hummer. Or perhaps your local video store: rent a game, $5/per ...These reactions are also called the light-independent reactions because they are not directly driven by light. In the Calvin cycle, carbon atoms from CO 2 are fixed (incorporated into organic molecules) and used to build three-carbon sugars.
