reactants
I believe they get their from the Sun to start the reaction :)oxygen
Either an energy source to start the reaction or a catalyst.
The energy needed to start a chemical reaction is called the activation energy :)
The substances at the start of a chemical reaction are known as reactants. Reactants are the molecules or compounds that undergo a chemical change during the reaction. They are typically written on the left side of a chemical equation, while the products of the reaction are written on the right side. The reactants are consumed during the reaction to form the products.
Reactants
A substance that lowers the energy needed to start a chemical reaction is a catalyst.
RuBP made during the dark reaction is used to start the reaction again. novanet.
It is neither, the reaction is the process. The chemicals 'put in' to the reaction are called reactants, and those formed by the reaction are products
The substance present at the start of a chemical reaction is called a reactant. Reactants are the starting materials that undergo chemical changes to form products during a reaction.
you would use reaction time at the start.
