myosin
n=6
a: Myosin ~
b: a robot walker on an actin racetrack
What: "Myosin is like a robot walker on an actin racetrack. The robot uses ATP for energy. Each stepwise cycle requires ATP hydrolysis, but there is more energy in the action than can be accounted for by the ATP alone. The researchers determined that, as has long been suspected, the structure of the motor allows random thermal motion to be captured as with a ratchet."

Muscle Contraction
a: Myosin ~
b: an oar in the water
What: "It turns out the there are only two proteins in the entire biosphere that can interact in such a way as to produce motion--actin and myosin. Actin is like the water, and myosin is like the oar."

a: Myosin ~
b: claw that is attached to the actin
What: "Myosin and actin are the two proteins that actually cause the muscle to contract. Myosin is like a claw that is attached to the actin, which is like a ladder with rungs. The myosin goes through a cycle to produce contraction:"...
1. ATP binds to the myosin head, causing it to release the actin filament
2. The ATP is hydrolysed into ADP and phosphate, the energy is used to "cock" the myosin into a high energy state
3. The phosphate is released, and the myosin is forced back into the actin. Now, the myosin is one "rung" forward
4. The ADP is then ejected, step 1 is re-initiated
..."You could think of it as the myosin crawls up the actin. Its like a ratchet mechanism"

A Whole Book Of Medical Analogies
a: Myosin ~
b: a hot dog surrounded by a thin, holey skin
What: "Also, if we think of actin as bacon wraps, the actin would be the hot dog, the bacon wrapped around it is the tropomyosin, and the troponin is the toothpick. A myofibril is like a hot dog surrounded by a thin, holey skin (SR). These are chilidogs because between the hot dogs are chili beans (mitochondria). The sarcolemma would be the bun." See the other in this link which is a whole book of teaching analogies for human physiology.

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.
