Where do high energy electrons that are produced in photosynthesis eventually get passed to?

The high-energy electron travels down a short second leg of the electron transport chain. At the end of the chain, the electron is passed to NADP +start superscript, plus, end superscript (along with a second electron from the same pathway) to make NADPH.

Where are the high-energy electrons at the end of photosynthesis?

The high-energy electrons are passed to the electron transport chain, a series of electron carriers that shuttle high-energy electrons during ATP-generating reactions. The thylakoid membrane provides new electrons to chlorophyll from water molecules.

Where does photosynthesis transfer energy to?

photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

Where does the energy come from in photosynthesis and where it ends up?

During the process of photosynthesis, light penetrates the cell and passes into the chloroplast. The light energy is intercepted by chlorophyll molecules on the granal stacks. Some of the light energy is converted to chemical energy. During this process, a phosphate is added to a molecule to cause the formation of ATP.

Where do the electrons from photosystem I ultimately go after they are passed through the electron transport proteins?

Where do the electrons from photosystem I ultimately go after they are passed through the electron transport proteins? They are pumped out of the cell.

What is high energy electrons?

High-energy electrons are released from NADH and FADH2, and they move along electron transport chains, like those used in photosynthesis. … This energy is used to pump hydrogen ions (from NADH and FADH2) across the inner membrane, from the matrix into the intermembrane space.

What passes high energy electrons to the electron transport chain?

High energy elections are passed into the electron transport chain by means of an electron carrier called NADH.

What energy does photosynthesis produce?

Most life on Earth depends on photosynthesis. The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O2) and chemical energy stored in glucose (a sugar).

Which process produces the energy that is used in photosynthesis?

During photosynthesis, “producers” like green plants, algae and some bacteria convert light energy from the sun into chemical energy. Photosynthesis produces chemical energy in the form of glucose, a carbohydrate or sugar.

How do you find the total energy transferred during photosynthesis?

The energy (e) of a photon is given by the equation e = hc/λ, where c is the velocity of light, h is Planck’s constant, and λ is the light wavelength. The energy (E) of an einstein is E = Ne = Nhc/λ = 28,600/λ, when E is in kilocalories and λ is given in nanometres (nm; 1 nm = 109 metres).

Where does the energy come from to make ATP at the chloroplast?

Chloroplasts capture light energy from the sun to produce the free energy stored in ATP and NADPH through a process called photosynthesis.

Where is energy stored in plants?

Plants store their energy in the form of starch, which is a complex carbohydrate that can be broken down into a simple carbohydrate (glucose) for the plant to use for energy. Plant cells store starch in storage organelles like all cells do.

What happens to the chemical energy produced by photosynthesis?

Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. The energy used to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as cellular respiration.

Where does the electron come from in photosynthesis?

In (a) photosystem II, the electron comes from the splitting of water, which releases oxygen as a waste product. In (b) photosystem I, the electron comes from the chloroplast electron transport chain. The two photosystems absorb light energy through proteins containing pigments, such as chlorophyll.

How are electrons generated in photosynthesis?

When light is absorbed by one of the pigments in photosystem II, energy is passed inward from pigment to pigment until it reaches the reaction center. There, energy is transferred to P680, boosting an electron to a high energy level (forming P680*).

What happens to the free energy released as electrons are passed from photosystem II to photosystem I through a series of electron carriers?

What happens to the free energy released as electrons are passed from photosystem II to photosystem I through a series of electron carriers? It is used to establish and maintain a proton gradient.
