5.9: Cellular Respiration
As you can see from Figure 5.9.6 5.9. 6, a mitochondrion has an inner and outer membrane. The space between the inner and outer membrane is called the intermembrane space. The space enclosed by the inner membrane is called the matrix. The second stage of cellular respiration, the Krebs cycle, takes place in the matrix.
Using light to make electrons even more energy efficient
Left or right-handed circularly-polarized light was used to generate the spin-up or spin-down state, and using that information, they were able to see the spins of the material in detail. At this scale in each domain, spins survived for much longer than expected. Because they were using microscopy, they were also able to see spin transport.

Changes in energy (article) | Energy | Khan Academy
If one object loses energy, another object has to gain that energy. Energy can be converted into different forms. For instance, a hairdryer takes electrical energy and converts it into thermal energy. When an object''s motion changes, so does its energy. If a bicycle slows down, it loses kinetic energy. That kinetic energy will be converted ...
How Solar Panels Absorb and Store Energy | Solar
Thin film solar panels are used more for commercial projects, on satellites and spacecraft. With either the silicon or thin film solar cells absorbing the sun''s light, the electrons do their thing.

Is there a way to harness electricity from lightning?
But even at 1 million joules, the typical lightning strike contains only about ¼ of a kilowatt-hour of power, which is not enough to make much difference on our electric bill. "We currently buy electricity at the cost of about 20 cents a kWh," he says. "The amount of energy from a lightning bolt would be worth only about a nickel.".
