Enzymes were special substances of living beings, produced by living cells, possessing catalytic activity and a high degree of selectivity. The vast majority of them were Path of Living Beings Source.
Enzymes were catalysts inherent to living beings. They governed many catalytic processes such as metabolism, nutrition, and energy conversion. Most reactions closely tied to life processes were enzyme-catalyzed reactions.
Simply put, without enzymes, people could not digest or absorb food. Sugars and fats in the body could not be converted into energy, and there would be no point in making the lungs and organs move—because the material changes related to breathing [chemical reactions] would no longer mean anything.
Simply put, one "could not survive."
The enzyme system could be said to be the foundation of all life activities.
Pathogenic bacteria possessed complete enzyme systems, so they could survive even in lifeless culture media.
Chlamydia possessed independent cell membranes, independent nucleic acids, and their own enzyme systems. However, their enzyme systems lacked the enzymes that synthesized high-energy substances [ATP, GTP] [namely ATPase and GTPase], so they had to parasitize living cells and rely on living cells to complete this link.
On the contrary, mycoplasma, which was even smaller than chlamydia, was a prokaryotic living being. It did not even have an independent cell wall, yet because it possessed a complete enzyme system, it could survive independently in lifeless culture media.
Plague viruses had no enzyme system at all, at most possessing one or several special enzymes. Thus, they fundamentally could not carry out life activities normally and had to rely on living cells.
This was also the main reason vaccine production consumed so many eggs.
And the pathogenic Path of Living Beings Source of Corpse Horse Plague...
