mitochondria
"I had an opportunity to talk with a friend's son who was a graduate student and was working with a researcher at a North Carolina University working with diabetes. He said the mitochondria is like a battery. It needs to be discharged as well as charged, i.e. exercised. Remember the ni-cad batteries that needed to be discharged fully or they lost capacity to retain their full charge. That is a chemical analogy."
"Now, the mitochondria is like a funky little bean,It supplies energy to the entire scene!" The link is a video that raps the part of the cell. This is really good for audio learners.
The mitochondria contains the energy for the cell and the power plant contains the power for the city.
A mitochondria is like a tiny furnace contained in each cell in the body. Mitochondria generate energy inside each cell by burning food in the presence of oxygen. This is why cells that are fully oxygenated have a higher level of energy. But again, oxygen can be both friend and foe. This firing process ends up subjecting the mitochondria themselves to high levels of free radical damage. As we age, mitochondria become so damaged by these free radicals that they lose their ability to function efficiently.
"The mitochondria is like the kitchen because that's where they make the food and provide energy to the people in the castle"

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.
