ENZYMES AND DNA 2

Enzymes are proteins that act as catalysts with living cells and naturally produced in the body.

Catalysts accelerate chemical reactions without being permanently altered or absorbed. A

chemical reaction is a process that coverts one or more substances to another type of substance.

The substances upon which enzymes may act are called substrates. An enzyme can speed up the

same chemical process repeatedly which keeps us alive. Every enzyme has a certain sequence of

amino acids set by a gene in the cell’s nucleus. The surface of enzymes provides a reaction

surface for reagents called active site.

An enzyme’s shape is adaptive to its function. Enzymes break down large complex food

molecules and are the key molecules during the digestion process. There are three digestive

enzymes; protease, lipase, amylase. Protease breaks down proteins into amino acids necessary

for bodybuilding and muscle repair. Lipase breaks down starches and carbohydrates into sugars

which provide energy while amylase converts lipids (fats and oils) into glycerol and fatty acids.

These make the products easily absorbed onto bloodstream.

Enzymes perform an important role in metabolism. Metabolism is the removal of toxic wastes

from our body. Enzymes are involved in the breakdown of large molecules meeting body needs.

When we consume too much food and liquid substances they are broken down to serve different

purposes in the body with the aid of enzymes in the digestion process but when in excess they

are treated as toxins and excreted in urine or stool form. Excretion in the kidney is done by

nephron through filtering blood (performed by nephron filters) and the loop secretes a few

substances. Enzymes presence in the kidney is essential as it prevents excretion of useful

substances like amino acids by breaking them down to a re-absorbable manner example leucine

aminopeptidase and cysteine amino peptidase (Pharr & Keller, (2017).
