Do enzymes really work?

I'm curious, can you elaborate on the mechanics behind how enzymes truly function? Are they simply catalysts that speed up chemical reactions, or is there more to their role in biological processes? How do they specifically recognize and bind to their target molecules, and what factors influence their efficiency and specificity? Understanding the intricacies of enzyme function seems crucial in fields like biochemistry, medicine, and even potentially in the realm of cryptocurrency and finance, where we often deal with complex systems and processes. So, do enzymes really work, and if so, how do they do it?
