I assume you are asking about carbon dioxide.
Nicholas de Saussure
Rubisco, ribulose bisphosphate carboxylase, is a protein molecule present in plant cells. It takes part in photosynthesis and converts inorganic CO2 into organic forms containing C-C bonds and H atoms. These are used to sustain plants in the form of sucrose (table sugar) or stored as starch
Chlorophyll is the molecule responsible for first capturing radiant energy from sunlight during photosynthesis. It is a pigment found in plants that absorbs light energy, which is then used to convert carbon dioxide and water into glucose and oxygen.
First of all it's not photosynthesis II, its photosystem II. well basically, the hydrogen atom within the water molecule loses its electrons and the electrons basically travels through all the photosytems via electron transport chains, towards the NADP Reductase where NADP+ is attached with the electrons from the hydrogen atoms of the water molecule to form NADPH
Chlorophyll molecule
The first molecule to provide electrons for photosynthesis is water. Water is split into oxygen, protons, and electrons during the light-dependent reactions of photosynthesis. These electrons are then used to drive the production of ATP and NADPH, which are needed for the Calvin cycle to convert carbon dioxide into glucose.

No, "begun" is not a present tense verb. It is the past participle form of the verb "begin" and is used to create past perfect or present perfect tense. The present tense of "begin" is "begins" (third person singular) or "begin" (first/second person singular and all plural forms).

Began is past tense. Begin is present tense.Sample text:"Let's begin at the beginning. It was early last year that I first began to realise that my memory was not good as I had thought. But I can't remember what it was that made me realise this."
The Roman Empire(present-day Italy) was the first to establish Christianity as an official religion.
RuB binds carbon dioxide (CO2) and it is the first step of carbon fixation - incorporating inorganic carbon into a organic molecule.

It is unsure were the first oxygen molecule came from came from, but my bet was that it was from the process "Outgassing" in which Water, Carbon Dioxide, and other fluids, were spewed out of volcanoes. The Carbon Dioxide was used by Cyanobacteria, or Stromatolites(sp?),in photosynthesis, thus producing oxygen.
At the beginning of translation, the first tRNA molecule, carrying the amino acid methionine, binds to the start codon (AUG) on the mRNA. This tRNA molecule recognizes the start codon through base pairing and initiates the assembly of the ribosome on the mRNA strand.
Water is required for the 'photolysis of water' which is the first stage of photosynthesis. Light enters the cell and strikes the water molecule splitting it into Hydrogen and Oxygen (from H2O).
