Enzymes are specialized proteins that speed up chemical reactions (biological catalysts) Without enzymes, cellular chemical reactions could not occur fast enough to maintain life.

Enzyme Activity:

–      enzyme binds to the reactants, called the substrate(s), of a chemical reaction

–      the substrate joins with the enzyme at the enzymes active site forming an enzyme-substrate complex

"Be Bold" No-Essay $10,000 Scholarship

The $10,000 “Be Bold” Scholarship is a no-essay scholarship that will be awarded to the applicant with the boldest profile. To us, boldest does not mean “best”, or “most accomplished”. Being bold means being: Earnest, Determined, Moving. The scholarship will be awarded to the student whose profile is most bold, according to these characteristics.

–      after the enzyme-substrate complex forms the enzyme-catalyzed reaction occurs

–      enzyme releases the product(s) and the enzyme is ready to bind to more substrate

Enzyme Characteristics:

–      enzymes are reusable

–      enzymes are specific to their particular substrate(s) as their active sites are designed to precisely fit and accept the substrate molecules

How do Enzymes speed up chemical reactions?

–      lower the amount of energy that must be supplied for the reaction to occur (activiation energy)

Thousands of different chemical reactions must occur in cells to make life possible.

Each reaction requires its own specialized enzyme in order to proceed efficiently.

Enzymes are biological molecules that catalyze chemical reactions.A living system controls its activity through enzymes. An enzyme is a protein molecule that is a biological catalyst with three characteristics. First, the basic function of an enzyme is to increase the rate of a reaction. Most cellular reactions occur about a million times faster than they would in the absence of an enzyme. Second, most enzymes act specifically with only one reactant to produce products. In enzymatic reactions, the molecules at the beginning of the process, called substrates, are converted into different molecules, called products. Almost all chemical reactions in a… Read more »
