biochemical pathway
"A biochemical pathway is like an assembly line," says Narcross, a PhD student in biology. "What we're trying do is to take that assembly line out of opium poppies and put it into yeast. The trouble is, we can't just ask for the plans. It takes a lot of work to figure out how the plant does what it does."
"A biochemical pathway is like a product producing assembly line in a factory, you have several different proteins / enzymes working together at different points "
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
