An enzyme that betters the chance of an organism surviving.

Do you mean that some are fast and some are slow? Enzymes have evolved to maintain a balance with a whole lot of other enzymes. Some are slow because they need to act as a bit of a bottleneck to prevent too much of a particular product being generated, or too much of a molecule being consumed too quickly.

Some need to act very quickly to prevent buildup of a product eg carbonic anhydrase is an extremely fast enzyme that converts CO2 to HCO3-.

Additionally, some enzymes are very specific and act on one substrate only, whereas some are promiscuous and can act on a range of different substrates. Variety is the spice of life!

Hope this helps.

Cheers,
