THE MIRACLES THAT ARE ENZYMES…
Enzymes run and operate the entire body and the sad truth is, without them, we wouldn’t be alive.
Enzymes catalyze bodily processes, thus enabling the synthesis of other biomolecules by numerous organism during glycolysis, the Krebs cycle etc. (Meyer, 2014) (without them biochemical reactions would be too slow to sustain life) . They are are specialized protein molecules which just happen to be biologically active, due to their quaternary structure and any minor change in their amino acid sequence can change the way the enzyme acts.
As they are usually unaltered by chemical reactions, they’re basically re-used, so large amounts aren’t necessarily needed to do their jobs (Novozymes.com. 2014).
Quick question… If all enzymes are proteins,are all proteins enzymes?
Biologically active proteins that function as catalysts in biochemical reactions are enzymes. However, since you’ve been reading our blog religiously that should’ve been obvious… right? 😀
DID YOU KNOW? Enzymes don’t attach to living cells, however, they do digest proteins in dead cells.
Enzymes can’t pass through of a living cell’s membrane, but upon its death, the membrane loses its carefully controlled selective permeability and the enzyme can act upon it (Meyer, 2014).
There are hundreds of enzymes in cells alone, that control cell activity and defends us against microbes such as bacteria and viruses.
THE ENEMY OF THE ENZYME!!!
Enzymes are sensitive to heat and changes in the pH in their surroundings. That’s why when food is cooked at high heat or processed for consumption, enzymes which are important for digestion of the food are killed.
