C3 Photosynthesis. Plants which use only the Calvin cycle for fixing the carbon dioxide from the air are known as C3 plants. In the first step of the cycle CO 2 reacts with RuBP to produce two 3-carbon molecules of 3-phosphoglyceric acid (3-PGA).4 plants almost never saturate with light and under hot, dry conditions much outperform C3 plants. They use a two-stage process were CO 2 is fixed in thin-walled mesophyll cells to form a 4-carbon intermediate, typically malate (malic acid).
A molecular formula lists the numbers of the atoms of a specific element in a compound. A structural formula is a picture of how the atoms in a specific molecule are connectedâ¦, with each atom represented by its chemical symbol. For example, oxygen's molecular formula is O2. Its structural formula is O-O.
The empirical formula is the simplest formula for a compound. A molecular formula is the same as or a multiple of the empirical formula, and is based on the actual number of atoms of each type in the compound.or example, if the empirical formula of a compound is C 3 H 8, its molecular formula may be C 3 H 8, C 6 H 16, etc. An empirical formula is often calculated from elemental composition data. The weight percentage of each of the elements present in the compound is given by this elemental composition.
