What happens during the electron transport chain of the light reactions quizlet?

What happens during the electron transport chain of the light reactions quizlet?

What happens during the electron transport chain of the light reactions? The electrons get increasingly excited as they move up the chain. The electrons interact with oxygen to move up the chain. The electrons release their energy, which is captured by ATP and NADPH.

What happens during the electron transport chain of the light reactions?

During the light-dependent reactions, an electron that’s excited in PSII is passed down an electron transport chain to PSI (losing energy along the way). In PSI, the electron is excited again and passed down the second leg of the electron transport chain to a final electron acceptor.

Which process is part of the light reaction quizlet?

The light reactions take place after the Calvin Cycle. The light reactions produce chemical energy in the form of NADPH and ATP. One molecule of water is produced for every electron that moves through photosystem II. The light reactions take place inside the thylakoids of chloroplasts.

Where is the electron transport chain quizlet?

The electron transport chain takes place within the inner membrane of the mitochondria.

What is the role of the electron transport chain in photosynthesis quizlet?

What is the function of the electron transport chain during photosynthesis? The electron transport chain helps to move electrons from PS 2 to PS 1. It makes oxidation-reduction reactions within the photosystems.

What is the role of electron transport chain in photosynthesis?

Electron transport helps establish a proton gradient that powers ATP production and also stores energy in the reduced coenzyme NADPH. This energy is used to power the Calvin Cycle to produce sugar and other carbohydrates.

What is the role of electron transport chains in photosynthesis?

Photosynthetic electron transport converts free and abundant solar energy into reducing power and chemical energy for producing biomass and biofuels through transferring electrons sequentially from H2O through Photosystem II and then Photosystem I to NADP+ in chloroplasts of higher plants and photosynthetic algae or in …

In what order do the electrons move through the electron transport chain?

The electrons must travel through special proteins stuck in the thylakoid membrane. They go through the first special protein (the photosystem II protein) and down the electron transport chain. Then they pass through a second special protein (photosystem I protein).

In what order do the electrons move through the electron transport chain quizlet?

Electrons move through the electron transport chain by electron carriers. Electrons in complex I flow from NADH through complex 1 to Q in complex III. Electrons in complex II flow from succinate to FADH2 to Q in complex III.

What is true about the electron transport chain ETC quizlet?

What is true about the electron transport chain (ETC)? The largest byproduct of the electron transport chain is carbon dioxide. The electron transport chain takes place in the cytoplasm of the cell.

What is the process of the electron transport chain?

The electron transport chain is a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation. It occurs in mitochondria in both cellular respiration and photosynthesis.

Where is the electron transport chain in photosynthesis?

the thylakoid membrane
In photosynthetic eukaryotes, the electron transport chain is found on the thylakoid membrane. Here, light energy drives electron transport through a proton pump and the resulting proton gradient causes subsequent synthesis of ATP.

What is the electron transport chain in simple terms?

The electron transport chain is a cluster of proteins that transfer electrons through a membrane within mitochondria to form a gradient of protons that drives the creation of adenosine triphosphate (ATP).

What is the primary role of the electron transport chain quizlet?

The main purpose of the electron transport chain is to build up a surplus of hydrogen ions (protons) in the intermembrane space sp that there will be a concentration gradient compared to the matrix of the mitochondria. This will drive ATP synthase.

What is the electron transport chain part of?

The electron transport chain (Figure 1) is the last component of aerobic respiration and is the only part of glucose metabolism that uses atmospheric oxygen. Oxygen continuously diffuses into plants; in animals, it enters the body through the respiratory system.

Which is the role of the electron transport chain in the process of photosynthesis quizlet?

It happens in light reactions in the Thylakoid membrane. What is the function of the electron transport chain during photosynthesis? The electron transport chain helps to move electrons from PS 2 to PS 1. It makes oxidation-reduction reactions within the photosystems.

What is electron transport chain reaction?

What does the electron transport chain consist of?

The electron transport chain is composed of four large, multiprotein complexes embedded in the inner mitochondrial membrane and two small diffusible electron carriers shuttling electrons between them.
