How is energy transferred into conductors and insulators?
In conductors, energy is transferred through the movement of free electrons. These electrons can carry thermal or electrical energy easily due to their ability to flow. In insulators, energy is transferred mainly through lattice vibrations, as the electrons in insulators are not as free to move and conduct energy.
How can energy be transferred by means of electrons?
Energy can be transferred by means of electrons through processes like electrical current flow in a circuit. When electrons move through a conductor, they carry energy from one point to another, allowing electrical devices to operate. This energy transfer can result in the production of light, heat, sound, or other forms of energy.
What is the relationship between frequency and kinetic energy in photoelectric effect?
In the photoelectric effect, increasing the frequency of incident light increases the kinetic energy of the emitted electrons. This is because higher frequency light photons carry more energy, which can be transferred to the electrons during the photoelectric effect.
Where do electrons get there energy from photostem 2?
Electrons in photosystem II get their energy from sunlight. When photons from sunlight are absorbed by the chlorophyll molecules in the photosystem, the energy is transferred to electrons, allowing them to become excited and drive the process of photosynthesis.
When energy is transferred in an ecosystem potential energy is lost as?
When energy is transferred in an ecosystem, potential energy is lost as heat. As organisms consume food, energy is converted to fuel various life processes. This energy is then released as heat during cellular respiration, contributing to the overall entropy of the system.
During electrons are transferred and energy is released.?
exothermic chemical reactions
During what electrons are transferred and energy is released.?
exothermic chemical reactions
Where is NADPH electrons from?
NADPH electrons are ultimately derived from the high-energy electrons transferred from nutrients such as glucose during cellular respiration. These electrons are transferred through a series of reactions that generate NADPH in the cell.
How does NAD gain energy cellular respiration?
NAD gains energy during cellular respiration by accepting high-energy electrons released during the breakdown of glucose. These electrons are transferred to NAD+ and converted into NADH, which can then participate in the electron transport chain to generate ATP, the cell's primary energy source.

In insulators, energy is transferred mainly through lattice vibrations, as the electrons in insulators are not as free to move and conduct energy.
Which molecule are high-energy electrons from glycolysis and the Krebs cycle ultimately transferred to?
High-energy electrons from glycolysis and the Krebs cycle are ultimately transferred to oxygen molecules during oxidative phosphorylation in the electron transport chain to produce ATP.
What caputures energy from sunlight during photosynthesis?
The photosynthetic pigments of the organism capture the light energy from the sun and the energy is transferred to chlorophyll "a" so that it's electrons can become excited.
Where is energy stored in NADH andFADH?
In NADH and FADH2, energy is stored in the high-energy electrons that are carried by these molecules. During cellular respiration, these electrons are transferred to the electron transport chain, where their energy is used to create a proton gradient that drives ATP synthesis.
What happens to electrons during cellular respiration?
During cellular respiration, electrons are transferred along the electron transport chain, releasing energy at each step. These electrons ultimately combine with oxygen to form water, facilitating the production of ATP through oxidative phosphorylation.
What is the name of the energy that electrons give up?
The energy that electrons give up is typically referred to as released energy or energy transfer. When electrons move between energy levels within an atom or are transferred between atoms in a chemical reaction, they can release energy in the form of light, heat, or kinetic energy.
Where do electrons get there energy in photosystem 2?
