Where does ETS occur?

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 does ETS occur in mitochondria?

The ETS is a series of electron carriers embedded in the inner mitochondrial membrane that shuttles electrons from NADH and FADH2 to molecular O2. In this process, protons are pumped from the mitochondrial matrix to the intermembrane space.

Where does ETS take place in the cell?

An electron transport system (ETS) is composed of a series of membrane-associated protein complexes and associated mobile accessory electron carriers. The ETS is embedded in the cytoplasmic membrane of prokaryotes and the inner mitochondrial membrane of eukaryotes.

Where is etc located in plants?

Plant cells have mitochondria as well; they produce glucose via photosynthesis, and then that is used in cellular respiration and, eventually, the electron transport chain in the mitochondria. The ETC reactions take place on and across the inner membrane of the mitochondria.

Which of the following is a component of ETS in mitochondria?

The correct Answer is option (C) Cytochrome oxidase.

Where is respiratory electron transport system ETS ETS located in plants?

Electron Transport System (ETS) is located in mitochondrial.

Where cytochromes are found?

They are present in bacteria, chloroplasts, and mitochondria. The mitochondrial b-type cytochromes are normally embedded in membranes as part of complex II of the electron transport system.

Where are stationary electron carriers located?

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.

What are the components of ETS?

The electron transport chain is also called the Cytochrome oxidase system or as the Respiratory chain. The components of the chain include FMN, Fe–S centers, coenzyme Q, and a series of cytochromes (b, c1, c, and aa3).

How many cytochromes are involved in ETS?

There are five different cytochromes in the respiratory chain. Because the hemes in different cytochromes have slightly different structures and (more...)

Which of the following is the complex III of ETS?

Complex II and complex III of ETS are NADH dehydrogenase and cytochrome oxidase complex respectively.

Which of the following is the main constituent of the cytochrome?

Cytochromes are redox-active proteins containing a heme, with a central Fe atom at its core, as a cofactor. They are involved in electron transport chain and redox catalysis. They are classified according to the type of heme and its mode of binding.

What are the four complexes of the electron transport chain?

The ETC proteins in a general order are complex I, complex II, coenzyme Q, complex III, cytochrome C, and complex IV. Coenzyme Q, also known as ubiquinone (CoQ), is made up of quinone and a hydrophobic tail. Its purpose is to function as an electron carrier and transfer electrons to complex III.

Where does oxidative phosphorylation take place?

Oxidative phosphorylation occurs in the mitochondria of all animal and plant tissues, and is a coupled process between the oxidation of substrates and production of ATP. As the Kreb's cycle runs, hydrogen ions (or electrons) are carried by the two carrier molecules NAD or FAD to the electron transport pumps.

In what order do 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).
