What the relationship between reactant product and substrate?

Answer 1

What is the relationship between substrates and enzymes in a chemical reaction?

Enzymes bind with chemical reactants called substrates. There may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. In some reactions, a single-reactant substrate is broken down into multiple products. In others, two substrates may come together to create one larger molecule. Two reactants might also enter a reaction, both become modified, and leave the reaction as two products.

The substrate binds to the enzyme at the active site. Since enzymes are proteins, this site is composed of a unique combination of amino acid residues (side chains or R groups). Each amino acid residue can be large or small; weakly acidic or basic; hydrophilic or hydrophobic; and positively-charged, negatively-charged, or neutral. The positions, sequences, structures, and properties of these residues create a very specific chemical environment within the active site. A specific chemical substrate matches this site like a jigsaw puzzle piece and makes the enzyme specific to its substrate.

Answer 2

Enzymes are organic catalysts that permit specific chemical reactions to occur rapidly in cells. Each enzyme attaches to specific reactant or reactants. It is these reactant/s that are referred to as the SUBSTRATE.

Answer 3

In chemical reactions involving enzymes, the substrate proteins are huge molecules that will only react with each other if they're aligned just the right way. If they are permitted to interact with the enzymes present, the won't collide and react often enough for the reaction to do any good. The enzymes align the molecules, basically acting like "molecule shepherds," showing them the way they need to react. This speeds up the reaction greatly, making things like digestion possible.

Answer 4

Substrates are the molecules [biomolecules] that enzymes act upon to create Products [Bioproducts].

Answer 5

An enzyme speeds up a chemical reaction.
