What is the source of energy that provides the boost of electrons during photosynthesis quizlet?
-Photosynthesis is ultimately powered by light energy and respiration by the chemical energy of fuel molecules. ATP is not produced during photosynthesis, but only during cellular respiration.
What is the source of electrons during photosynthesis?
In photosynthesis, water is the source of electrons and their final destination is NADP+ to make NADPH. In mitochondria, NADH/FADH2 are electron sources and H2O is their final destination.
What is the source of energy that provides the boost?
Answer and Explanation: The basic source of energy that usually provides the boost to the electrons during photosynthesis is light.
What is the source of energy that provides the boost for electrons during photosynthesis ATP NADPH light cellular respiration?
light energy The light energy captured by chlorophyll molecules in the chloroplast provides the boost for the electrons. Photosynthesis converts light energy to chemical energy and stores it in the chemical bonds of sugar molecules, which can provide energy for later use or raw materials for biosynthesis.
What is the source of electrons?
Finally, the electron source can be either organic (organotrophs), inorganic (lithotrophs), or water (aquatrophs).
What is the source of electrons for the chloroplast electron transport chain?
What is the initial source of electrons for the chloroplast electron transport chain? The reaction center contains a pair of chlorophyll a molecules with a special property. Those two chlorophylls can undergo oxidation upon excitation; they can actually give up an electron in a process called a photoact.
Which of the following is the source of electrons for the light reactions?
Light reactions occur when plants synthesize food from carbon dioxide and water, referring specifically to the part of energy production that requires light and water to generate electrons needed for further synthesis. Water provides the electrons by splitting into hydrogen and oxygen atoms.
What is the source of energy in plant growth resources?
During photosynthesis, carbon dioxide, a gas, is combined with water and solar energy, and converted to carbohydrates, a solid. Formation of carbohydrates is a chemical way to store the sun's energy as “food.” Carbohydrates produced from photosynthesis provide energy for all plant growth and maintenance.
What is the source of energy that provides the excitement of electrons during the light reaction of photosynthesis?
Light Light is the source of energy for photosynthesis, and the first set of reactions which begin the process requires light – thus the name, light reactions, or light-dependent reactions. When light strikes chlorophyll (or an accessory pigment) within the chloroplast, it energizes electrons within that molecule.
What is the source of energy that drives photosynthesis sunlight hydrogen ions electrons oxygen?
Search for an answer or ask Weegy. sunlight hydrogen ions electrons oxygen Weegy: The source of energy that drives photosynthesis is the sunlight.
How are electrons energy sources?
When properly stimulated, electrons in these materials move from a lower level of energy up to a higher level of energy and occupy a different orbital. Then, at some point, these higher energy electrons give up their "extra" energy in the form of a photon of light, and fall back down to their original energy level.
What is electron energy?
A part of the electron energy is spent for kinetic energies of both atoms that are formed upon dissociative collision of an electron with an oxygen molecule.
Which is the source of electrons in the electron transport chain stage of respiration?
All of the electrons that enter the transport chain come from NADH and FADH 2start subscript, 2, end subscript molecules produced during earlier stages of cellular respiration: glycolysis, pyruvate oxidation, and the citric acid cycle.
What are the different electron sources in photosynthesis and respiration?

What is the source of electrons in plants?
Answer and Explanation: In the electron transport process of photosynthesis, water is used as the electron source.
Which of the following is a source of electrical energy?
The three major categories of energy for electricity generation are fossil fuels (coal, natural gas, and petroleum), nuclear energy, and renewable energy sources. Most electricity is generated with steam turbines using fossil fuels, nuclear, biomass, geothermal, and solar thermal energy.
Where do electrons that are excited by the energy in sunlight come from?
The light excites an electron from the chlorophyll a pair, which passes to the primary electron acceptor. The excited electron must then be replaced. In (a) photosystem II, the electron comes from the splitting of water, which releases oxygen as a waste product.
What provides electrons for the light reactions?
Light reactions occur when plants synthesize food from carbon dioxide and water, referring specifically to the part of energy production that requires light and water to generate electrons needed for further synthesis. Water provides the electrons by splitting into hydrogen and oxygen atoms.
What is the source of energy that drives photosynthesis sunlight?
The source of energy that drives photosynthesis is sunlight or light energy. The sun produces energy that travels to Earth and is absorbed by…
What is the source of energy that drives photosynthesis quizlet?
An electron carrier involved in photosynthesis. Light drives electrons from chlorophyll to NADP+, forming NADPH, which provides the high-energy electrons for the reduction of carbon dioxide to sugar in the Calvin cycle.
What is a source of electrons called?
We use two kinds of electron sources in TEMs: the first kind is called a thermionic source, which, as the name suggests, produces electrons when heated, and the second type is a field-emission source, which produces electrons when a large electric potential is applied between it and an anode.
What is the energy of an electron?
Electrons in a hydrogen atom must be in one of the allowed energy levels. If an electron is in the first energy level, it must have exactly -13.6 eV of energy. If it is in the second energy level, it must have -3.4 eV of energy….Energy Levels of Electrons.
| Energy Level | Energy |
|---|---|
| 2 | -3.4 eV |
| 3 | -1.51 eV |
| 4 | -.85 eV |
| 5 | -.54 eV |
How electrons can be energy source?
When properly stimulated, electrons in these materials move from a lower level of energy up to a higher level of energy and occupy a different orbital. Then, at some point, these higher energy electrons give up their "extra" energy in the form of a photon of light, and fall back down to their original energy level.
What is the source of energy for electron transport in the mitochondria?
During electron transport, energy is used to pump hydrogen ions across the mitochondrial inner membrane, from the matrix into the intermembrane space. A chemiosmotic gradient causes hydrogen ions to flow back across the mitochondrial membrane into the matrix, through ATP synthase, producing ATP.
What is the source of electrons in cellular respiration?

What gives energy to the electron moving through the electron transport chain?
As electrons move through the electron transport chain, they go from a higher to a lower energy level and are ultimately passed to oxygen (forming water). Energy released in the electron transport chain is captured as a proton gradient, which powers production of ATP by a membrane protein called ATP synthase.
Where do electrons get their energy in photosystem II?
The heart of photosystem II is the reaction center, where the energy of light is converted into the motion of energized electrons. At the center is a key chlorophyll molecule. When it absorbs light, one of its electrons is promoted to a higher energy.
What is the main source of energy?
The energy of the sun is the original source of most of the energy found on earth. We get solar heat energy from the sun, and sunlight can also be used to produce electricity from solar (photovoltaic) cells.
What is the best source of electrical energy?
