What type of chemical reaction must occur for electrons to flow from one molecule to the next and supplies the energy for metabolism?
The type of chemical reaction required for electrons to flow from one molecule to the next and provide energy for metabolism is a redox (reduction-oxidation) reaction. In this reaction, one molecule acts as a reducing agent, donating electrons, while the other molecule acts as an oxidizing agent, accepting the electrons. This transfer of electrons generates energy that can be used by the body for various metabolic processes.
What a pigment molecule that transfers electrons during light reaction?
The pigment molecule that transfers electrons during the light reaction is chlorophyll. Chlorophyll absorbs light energy and transfers electrons to the reaction center of the photosystem, initiating the flow of electrons through the electron transport chain. This process is essential for the conversion of light energy into chemical energy during photosynthesis.
How chemical energy is converted to chemical energy?
its because of the liberation of electrons in the submolecular level of a quimical reaction
When electrons are transferred from one molecule to another the molecule losing the electrons becomes and has a energy state?
When electrons are transferred from one molecule to another, the molecule losing the electrons becomes oxidized and typically has a higher energy state due to the loss of negatively charged particles. This process can result in the release of energy, as oxidation often occurs alongside a reduction reaction in the other molecule, which gains the electrons and becomes reduced. Consequently, the overall energy dynamics depend on the specific molecules involved and the context of the reaction.
What physically happens to a molecule when it absorbs a photon?
When a molecule absorbs a photon, its energy increases and the electrons in the molecule are excited to higher energy levels. This can lead to changes in the molecular structure or bond vibrations. In some cases, the molecule may undergo a chemical reaction or emit a photon in a process known as fluorescence or phosphorescence.
Where is chemical energy stored in a molecule?
Chemical energy is stored in the bonds between atoms within a molecule. When these bonds are broken during a chemical reaction, energy is either released or absorbed. The type and strength of these bonds determine the amount of potential energy stored in the molecule.
When the energy of sunlight moves to a chlorophyll molecule in a reaction center how does this impact an electron?
Electrons absorb the energy. Then it becomes exited
How do chemical energy is transferred in to electrical energy?
Chemical energy can be converted into electrical energy through a chemical reaction in a battery. When the battery is connected to a circuit, the reaction releases electrons, which flow through the circuit as an electric current, producing electrical energy.
If one molecule has more energy than another does it have a higher activation energy?
The activation energy refers to a chemical reaction.
Where is energy located in a molecule?
Energy is located in the bonds between atoms in a molecule, specifically in the chemical bonds that hold the atoms together. When these bonds are broken or formed during a chemical reaction, energy is either released or absorbed.

What is the energy pathway for a chemiluminescent source?
In chemiluminescence, a chemical reaction generates energy in the form of light. This reaction typically involves the oxidation of a luminophore molecule by a reactive species, such as hydrogen peroxide, resulting in the emission of light. The energy pathway involves the excitation of electrons in the luminophore molecule, followed by their return to the ground state, releasing photons in the form of light.
