Effective Design Strategies And Enzymes

This is a two part discussion post

Part 1: Effective Design Strategies

What do you think the most effective design strategies are, and why do you think that? Can you remember some outstanding graphics from advertising, posters or brochures?

Part 2: Enzymes

There are many different analogies for describing the way that enzymes work. For this discussion, develop your own analogy to describe the way that enzymes work. You may choose to develop an analogy that explains the way that enzymes interact with their substrates, or you may choose to pick a different aspect of enzyme mechanics. Include an outside source with your post.
