Which sentence best describes what happens after sunlight hits photo system 2?
After sunlight hits photosystem 2, it excites electrons within photosystem 2. These electrons are then passed down an electron transport chain to photosystem 1, where they help generate ATP through a series of redox reactions.
What is the energy that excites p680 and p700 is supplied by what?
The energy that excites P680 and P700 in photosystem II and photosystem I respectively is supplied by sunlight. More specifically, it is the photons of light energy absorbed by chlorophyll molecules within these photosystems that excites the electrons in P680 and P700 to higher energy states, initiating the process of photosynthesis.
How does a solar panel produce energy and convert sunlight into electricity?
A solar panel produces energy by converting sunlight into electricity through a process called the photovoltaic effect. When sunlight hits the solar panel, it excites the electrons in the silicon cells, creating an electric current. This current is then captured and converted into usable electricity for powering homes and devices.
What happens in the photosystem when it is hit by a photon of light?
When a photon of light hits the photosystem, it excites an electron in the reaction center of the photosystem. This electron is then passed along a series of proteins called the electron transport chain, generating ATP and reducing power in the form of NADPH. These energy carriers are used in the light-dependent reactions of photosynthesis to convert carbon dioxide into glucose.
What energy conversion takes place in a solar cell?
A solar cell converts sunlight directly into electricity by the photovoltaic effect. Sunlight is composed of photons, or "packets" of energy. These photons contain various amounts of energy corresponding to the different wavelengths of light. When photons strike a solar cell, they may be reflected or absorbed, or they may pass right through. When a photon is absorbed, the energy of the photon is transferred to an electron in an atom of the cell (which is actually a semiconductor). With its newfound energy, the electron is able to escape from its normal position associated with that atom to become part of the current in an electrical circuit. Hope that helps.
Sunlight excites electrons in the chlorophyll during the what?
Sunlight excites electrons in chlorophyll during the process of photosynthesis, where they are used to convert carbon dioxide and water into glucose and oxygen. This excitation of electrons is a key step in converting light energy into chemical energy that the plant can use for growth and metabolism.

Where do electrons get their energy in photosystem II?
From energy in photons

What happen to the light energy that is trapped by the chloroplast during the first stage of photosynthesis?
Light energy is not exactly trapped. The light energy excites the electron in the reaction centres of photosystem I and photosystem II. The electron excites and transfers to the electron transport chain ( chain of electron carriers), this produces ATP. Then the electron of photosystem II is transferred by photosystem I and the electron of the photosystem I is used with H+ and NADP to form NADPH. Photosystem II gets back an electron from photolysis of water.
When sunlight excites electrons how do the electrons change?
Depending on the energy (frequency) of the specific photon hitting the electron, one of three events happens: nothing, the electron is excited, or the electron leaves the atom. If the energy of the photon very high, the electron can absorb the energy and escape the nucleus' pull. This is called ionization. If the energy of the photon lines up with the energy spacing in the atoms energy levels, the electron will move to a higher energy state, becoming excited. The electron then returns to its original energy level, releasing the energy as light. If the energy of the photon does not fall into one of these categories, the electron does not interact with it. In terms of actually changing the electron, it only changes in energy, not any other property.
Where does the energy come from that excites the electrons in chlorophyll?
The energy that excites electrons in chlorophyll comes from sunlight. Specifically, chlorophyll absorbs light energy from the sun, which is then used to power the process of photosynthesis.

What is a physiological explanation for the effect of sunlight on plant growth?
the photon excites an electron that starts a reaction. the parts of the reaction are splitting a water molecule into oxygen, two protons, and two electrons. electrons replenish the excited electrons. protons are used in ETC, electron transport chain, and oxygen is released as waste. the ETC is used to make the energy for the plant to make glucose for the plant

An electron with a speed of 5 x 10to the 6 m collides with an atom the collision excites the atom from a 0 to 3.8 ev what is the speed of the electron?
You may want to re-phrase the question, since you've already stated the speed of the electron as 5000000 m/s.
