Calvin+cycle

**What is it?**
The Calvin Cycle is the part of photosynthesis that takes CO2, water, and photons, and turns it into Glucose. This occurs inside of plants, particularly inside the stroma of the chloroplast (an organelle), and is classified as a synthesizing reaction, meaning that it combines may of the reactants to form the product. The chemical equations is 3 CO2 + 6 NADPH + 5 H2O + 9 ATP → glyceraldehyde-3-phosphate (G3P) + 2 H+ + 6 NADP+ + 9 ADP + 8 Pi.

**What goes on?**
The Calvin cycle first takes place when a cell intakes 3CO2, which are just three molecules of carbon dioxide along with five molecules of H2O, otherwise known as water. The chain of carbon molecules result from the adding of CO2 to a carbon chain inside the chloroplast. During this process the molecules ATP and NADPH add energy into the equation, the energy required to produce the sugar C6H12O6. The byproduct oxygen is what we use to fuel our own bodies, and we also eat plants to gain the energy from the sugar produced by this process. The left over carbon chain is then fueled back into the cycle.

**Why is this chemical reaction important?**
Besides what we tend to believe, the main part of our diets consist of plants, in one form or another. Sure, you may eat beef and other animals, the fact is that they ate plants. The plants that sustained them, in turn sustain us. The reason we are alive right now is because of plants. The plants that we eat to obtain energy form the energy we need through the Calvin cycle. That is why the Calvin cycle is important.

**Why are chemical reactions important?**
Chemical reactions occur in every day life and we rarely notice. While combustion and photosynthesis are important reactions, without one or more reactions, life would not exist at all. Every living thing requires energy. Without energy in the form of chemical bonds, there would no way to obtain that energy in a usable form. Every living thing, in turn, then requires chemical reactions to live. The Calvin cycle is a chemical reaction that occurs inside of plants, making all life that does not produce it's own energy possible.

**Conclusion**
The Calvin cycle is a series of reactions inside a plant cell's chloroplast that creates sugars. The sugars that are created in this cycle sustain all of the non-producer life on Earth, besides some extremophiles. It plays a vital role in all that we eat and are made up of.
