How can the rate of photosynthesis be measured using products or reactants.

hope it mark me as brainlieast.

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.

in a chemical reaction, the atoms and molecules produced by the reaction are called products. no new atoms are created, and no atoms are destroyed. in a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
