A theoretical model is presented to account for the physical mechanism of energy transfer from antenna molecules to the reaction centers in photosynthesis. The energy transfer is described by a generalized transport equation or "master equation". The solution of this equation for the proposed model gives a relationship between the antennae interaction energy and the transfer rate. The results are shown to be in agreement with inter-antenna transfer rates calculated from experimental fluorescence lifetimes. Previous theories were based either on the Förster mechanism, which is valid for very small interaction energies, or an exciton model valid for very large interactions, but experimental results seemed to indicate that the actual situation was intermediate between these two. The Förster theory and the exciton model are limiting cases of the master equation.

∙ 12y agoThe energy transfer in a plant during photosynthesis is that the plant uses the sunlight to create sugar. This sugar (Glucose for most professor's pleasure) is then used by the plant for food. The energy transfer is the sunlight to sugar(glucose) to food for the plant

What types of energy are involved with photosynthesis?
It produces stored energy, so that the plant can use it later.
How are pigments involved in the photosynthesis process?
The pigments are responsible for capturing the light energy from the sun and converting it to chemical energy. This is the first step of photosynthesis, so the pigments are responsible for initiating photosynthesis.
Electron transfer systems concentrate energy that is then used to generate ATP in?
aerobic respiration,photosynthesis and mitochondria
Where does the energy for photosynthesis come from and what part of the plant pigments are involved in photosynthesis?
The energy for photosynthesis comes from respiration. The plant takes in oxygen and uses it for energy with in its cells. The chloroplast have a green substance called chlorophyll which absorbes the light needed for photosynthesis. the reaction happens there. Unfortunately the previous answer is not quite right. The ultimate source of energy for photosynthesis is sunlight. Plants convert the light energy into chemical energy in the form of glucose, which they can then use as a source of energy in their cells. Energy is released from glucose by respiration.
What is a reactant in the general photosynthesis equation?
Photosynthesis is the process by which green plants manufacture their food. The reactants involved in this process are carbon dioxide, water and light energy.
What is the process by which energy transfer takes place?
Photosynthesis
Is photosynthesis a system?
Photosynthesis is not a system. It is a process in plants. It is very important process.Photosynthesis is a process of making sugars from CO2 and water by using light energy. Photosystem I and photosystem II are involved in this process to transfer electrons across the membrane. Photosynthesis occurs in plants algae and certain bacteria.
The first transfer of energy on earth occurs?
during photosynthesis
Is chlorophyll energized in photosynthesis?
Yes, chlorophyll is energized in photosynthesis. When chlorophyll absorbs light energy, it becomes excited and enters an energized state. This energized chlorophyll is then able to transfer the absorbed energy to other molecules involved in the process of photosynthesis, which ultimately leads to the conversion of light energy into chemical energy.
What is the Green organelle involved in energy production and photosynthesis?
The chloroplast.
How is the sun's energy transfer to chemical energy?
That take place in chlorophylls. Process is called photosynthesis
What is involved in photosynthesis by capturing energy from sunlight to make energy-rich food?
Chloroplasts.
Name the energy transfer process plants use to convert the sun's energy into stored chemical energy?
photosynthesis.
How is photosynthesis a transfer of energy?
The process turns light energy into chemical potential energy (the sun's light is used to create sugars).
What is the meaning of a Process which begins transfer of materials and energy throughout a forest ecosystem is a?
It is photosynthesis.
What groups of molecules are involved in photosynthesis and the trapping of energy?
It is about pigments. they are absorbers of light.
Is energy transfer involved in every physical and chemical change?
No
