do electrons store or consume energy

7.2: Energy in Living Systems

Electrons and Energy. The removal of an electron from a molecule via a process called oxidation results in a decrease in the potential energy stored in the oxidized compound. When oxidation occurs in the cell, the electron (sometimes as part of a hydrogen atom) does not remain un-bonded in the cytoplasm.

Life

Life - Energy, Carbon, Electrons: Organisms acquire energy by two general methods: by light or by chemical oxidation.

These autotrophs provide energy for the other organisms, the …

Capacitors article (article) | Khan Academy

Capacitors store energy by holding apart pairs of opposite charges. Since a positive charge and a negative charge attract each other and naturally want to come together, when they are held a fixed distance apart (for example, by a gap of insulating material such as air), their mutual attraction stores potential energy that is released if they are re-united.

energy

2. A (kilo)calorie is a unit of energy, while a watt is a unit of power, which describes the rate at which energy is expended. So a 100W bulb is using 100 joules a second. A kcal is about 4184 joules, so a 100W bulb takes about 42 seconds to consume (really: convert into light and heat) a kcal. The joule is the SI (derived) unit of energy.

Capacitance

Capacitance is the ability of a body to hold an electrical charge. Any object that can be electrically charged exhibits capacitance. A common form to store energy is with a device called a capacitor. In a parallel plate capacitor, capacitance is directly proportional to the surface area of the conductor plates and inversely proportional to the …

How are photons absorbed by electrons?

So, the way we see the photoelectric effect in High school is more like the phenomenological ideas that lead to quantum mechanics. But quantum mechanics actually does not treat light as a particle in the sense that we think of a ball with a given mass and energy going and hitting another one. Quantum mechanics rather use the "wave" functions.

Energy is not the same as force, although energy is transferred when a force is applied to a moving object. In electrostatics, charge carriers don''t contain energy …

7: How Cells Harvest Energy

If aerobic respiration occurs, then ATP will be produced using the energy of high-energy electrons carried by NADH or FADH2 to the electron transport chain. If aerobic respiration does not occur, NADH must be reoxidized to NAD+ for reuse as an electron carrier for the glycolytic pathway to continue. 7.9: Catabolism of Proteins and Fats
