Hi!

First post on this forum:)

My Question: what are the differences and similarities between catalytic mechanismes for carbonic anhydrase en serine proteases?

Thx

You must show your attempt first, before we can help you.  Fortunately there are some obvious differences.  Think about the common mechanisms of enzymatic catalysis, such as nucleophilic catalysis, general base catalysis, general acid catalysis.  You might also want to think about cofactors.
