How much energy is in the atmosphere?
How much energy is in the atmosphere? On average, 340 watts per square meter of solar energy arrives at the top of the atmosphere. Earth returns an equal amount of energy back to space by reflecting some incoming light and by radiating heat (thermal infrared energy). How does energy transfer in a TV? A television […]

Why is the electron transport chain so important?
Why is the electron transport chain so important? The ETC is the most important stage of cellular respiration from an energy point of view because it produces the most ATP. When a cell needs energy, it breaks the third phosphate group bond and uses the resulting energy. Which anaerobic process is responsible for producing ATP […]
