What are the products of the electron transport chain

The end products of electron transport are NAD+, FAD, water and protons. The protons end up outside the mitochondrial matrix because they are pumped across the cristal membrane using the free energy of electron transport.

What are the products of the electron transport chain quizlet?

Once ATP is created, the waste products of the electron transport chain are the hydrogen ions and the electrons.

What is the final product of the electron transport chain quizlet?

H2O (water) is formed as a final product of the electron transport chain.

What are the products and reactants of the electron transport chain?

The main biochemical reactants of the ETC are the electron donors succinate and nicotinamide adenine dinucleotide hydrate (NADH). These are generated by a process called the citric acid cycle (CAC). Fats and sugars are broken down into simpler molecules such as pyruvate, which then feed into the CAC.

What is a product of the electron transport chain started by photosystem II?

Photosystem II produces. both oxygen and high-energy electrons. Photosystem I initiates the electron transport chain that produces. NADPH.

What are the two main products of the ETC?

The products of the reactions in ETC complex I and complex II are the NAD and FAD molecules that are required in the citric acid cycle. As a result, the citric acid cycle is dependent on the ETC.

What are the products of the electron transport chain in the second stage of cellular respiration?

The second stage of cellular respiration is the transfer of the energy in pyruvate, which is the energy initially in glucose, into two energy carriers, NADH and FADH2. A small amount of ATP is also made during this process. This process occurs in a continuous cycle, named after its discover, Hans Krebs.

What are the final products of the electron transport chain and oxidative phosphorylation?

The end products of the electron transport chain are water and ATP. A number of intermediate compounds of the citric acid cycle can be diverted into the anabolism of other biochemical molecules, such as nonessential amino acids, sugars, and lipids.

What are the 3 reactants of the ETS in photosynthesis?

In photosynthesis, chlorophyll, water, and carbon dioxide are reactants.

Is ATP produced in the electron transport chain?

The electron transport chain takes place in the mitochondria. This stage converts the NADH into ATP. The electron transport chain works as a proton pump: it pumps hydrogen ions (protons) through the membrane, and only allows them back through a protein (ATP synthase) which makes ATP.

Article first time published on

Which compounds donate electrons to the electron transport chain?

NADH and FADH2 are both electron carriers that donate their electrons to the electron transport chain. The electrons ultimately reduce O2 to water in the final step of electron transport.

What is produced in photosystem 1?

Photosystem I (PSI, or plastocyanin–ferredoxin oxidoreductase) is one of two photosystems in the photosynthetic light reactions of algae, plants, and cyanobacteria. … Ultimately, the electrons that are transferred by Photosystem I are used to produce the moderate-energy hydrogen carrier NADPH.

What are the products of photosynthesis?

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product.

What are photosystem 1 and 2?

Photosystem I (PS I) and photosystem II (PS II) are two multi-subunit membrane-protein complexes involved in oxygenic photosynthesis. … The main difference between photosystem 1 and 2 is that PS I absorbs longer wavelengths of light (>680 nm) whereas PS II absorbs shorter wavelengths of light (<680 nm).

What are the products of the second stage of respiration?

The second step in cellular respiration is called the Krebs cycle. The Krebs cycle uses pyruvic acid to create ATP, along with additional molecules like NADH, FADH2, and CO2.

What are the three products of cellular respiration?

Cellular respiration is this process in which oxygen and glucose are used to create ATP, carbon dioxide, and water. ATP, carbon dioxide, and water are all products of this process because they are what is created. Carbon dioxide is released as a gas when you exhale.

What is produced from the third stage of cellular respiration the electron transport chain?

Cellular Respiration Stage III: Electron Transport Chain ETC, the final stage in cellular respiration produces 32 ATP. The Electron Transport Chain is the final stage of cellular respiration. In this stage, energy being transported by NADH and FADH2 is transferred to ATP.

What does the electron transport chain do?

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.

What are the 3 main steps of the electron transport chain?

Generation of a proton gradient across the mitochondrial membrane. Proton accumulation occurs in the intermembrane space of mitochondria.
Reduction of molecular oxygen and formation of water. …
ATP synthesis by chemiosmosis.

What is the electron transport chain used for?

The electron transport chain is used to pump protons into the intermembrane space. This establishes a proton gradient, allowing protons to be pumped through ATP synthase in order to create ATP. This method of ATP production is called oxidative phosphorylation.

What is the product and by product of photosynthesis?

The three important elements required for the photosynthesis process are Water, carbon dioxide and light. The product formed from this process, stored in the form of sugars, which are created from water and carbon dioxide. The by-product of the photosynthesis process is oxygen.

What are the products of photosynthesis quizlet?

The two products of photosynthesis are sugar and oxygen.

What are the products of electron transport phosphorylation?

Which compounds are the final products of oxidative phosphorylation?

When there is a high concentration of protons on the outside of the mitochondrial membrane, protons are pushed through ATP synthase. This movement of protons causes ATP synthase to spin, and bind ADP and Pi, producing ATP. Finally, ATP is made!

What is produced by these three prior processes that is used by the electron transport chain?

Recall in cellular respiration, the processes of glycolysis, pyruvate processing, and the citric acid cycle precede the electron transport chain. … each of these three processes produce ATP, which carries potential energy to the ETC b.

How many NADH are produced in the electron transport chain?

The two NADH produced in the cytoplasm produces 2 to 3 ATP each (4 to 6 total) by the electron transport system, the 8 NADH produced in the mitochondriaproduces three ATP each (24 total), and the 2 FADH2 adds its electrons to the electron transport system at a lower level than NADH, so they produce two ATP each (4 …

How does the electron transport chain produce energy?

In the electron transport chain, electrons are passed from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient. In chemiosmosis, the energy stored in the gradient is used to make ATP.

How many ATP are produced from the 10 NADH that enter the electron transport chain?

What about the FADH2? It donates its electrons at a slightly later step in the electron transport chain, so only two ATPs are produce for every FADH2 molecule. In a perfect world, the ten NADHs (10 x 3 ATPs) and two FADH2 (2 x 2 ATPs) molecules produced by the breakdown of each glucose molecule would yield 34 ATPs.

What is electron transport in photosynthesis?

Photosynthetic electron transport is the first stage of photosynthesis that produces chemically stored energy and uses solar photons to drive electron transport against a thermodynamic gradient.

What are the carrier proteins in the electron transport chain?

The following complexes are found in the electron transport chain: NADH dehydrogenase, cytochrome b-c1, cytochrome oxidase, and the complex that makes ATP, ATP synthase. In addition to these complexes, two mobile carriers are also involved: ubiquinone, and cytochrome c.

Does photosystem 2 use an electron transport chain?

In the photosystem II (PSII) reaction center, energy from sunlight is used to extract electrons from water. The electrons travel through the chloroplast electron transport chain to photosystem I (PSI), which reduces NADP+ to NADPH. The electron transport chain moves protons across the thylakoid membrane into the lumen.
