Enzymes are proteins that control the speed of chemical reactions in your body. Without enzymes, these reactions would take place too slowly to keep you alive. Some enzymes, like the ones in your gut, break down large molecules into smaller ones.
Science isn't just gathering factual information and data, it's a body of knowledge. It's a way of thinking about problems, and how to solve them. Science shapes everything in our world since everything revolves around natural rules.
It's thanks to computer <em>science </em>that you're able to be on this site right now. It's thanks to <em>science </em>as a whole that we have any of the technology we have today, and the cures for the many once <em>deadly </em>diseases. So, if you want to know how science shapes our world... Just look around you. =)
