The terms reactant and product can be used to describe constituents of individual enzymatic reactions or entire metabolic pathways. Reactants (or 'substrates') are the starting materials for a reaction, In the generic reaction shown below, A and B are the reactants. C and D are the products. CO2 and RUBP are the reactants in this reaction, Rubisco is the enzyme, and the product is two molecules of 3PGA. We can also refer to the reactants and products of entire metabolic pathways, such as of the light-independent reactions.
A. PLASTER IS A TIME TESTED PRODUCT: Plaster has been used as a swimming pool surface coating for the past 50 years. This experience has shown that plaster is a durable surface that can stand up to the environment of proper pool water chemistry.
Brushing will remove dirt and spores, and prevent algae from taking hold. Brush the walls, floor, and steps of the pool. Once youâve completed your brushing, vacuum the pool to dislodge and remove any spores that have settled on the bottom. 1  Use a steel brush for concrete or plaster pools.
