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 molecular formula is the formula of a discrete (single) molecule of the substance. The formula unit is generally defined in the same way as the empirical formula, which â¦ is the simplest whole number ratio of the elements Chemical formula includes both molecular and formula units.t shows the chemical makeup of a substance using the chemical symbols of the elements in that substance. Hydrochloric Acid is made up of Hydrogen and Chlorine, expressed at H â¦ Cl. Water is made up of 2 hydrogen atoms and an oxygen, expressed as H2O.
