What proteins are found in 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 are the proteins of the electron transport chain located in eukaryotes?

In eukaryotes, the electron transport chain is located in the inner mitochondrial membrane. In prokaryotes, it is located within the plasma membrane.

Where are the proteins of the electron transport chain located in chloroplasts?

The electron-transport proteins, utilized in stage 1 of photosynthesis, reside in the inner membrane of the chloroplast. ultimately passed on to a molecule of O2, to produce H2O.

Where are the proteins of the electron transport chain located in the mitochondria?

The inner membrane of mitochondria contains the proteins of the electron transport chain, and is the barrier allowing the formation of a H+ gradient for ATP production through ATP synthetase.

Where are the proteins of the electron transport chain located in prokaryotic cells that respire?

The only membrane in prokaryotes is the cellular membrane, that is where the ETC is located.

What are the proteins of the electron transport chain located quizlet?

Where are the proteins of the electron transport chain located? a proton gradient across a membrane.

Where do protons become concentrated in the chloroplast?

During photosynthetic electron transport, protons accumulate at high concentration inside the thylakoid space. The concentration gradient between the inside and outside of the thylakoids is the energy source used by the ATP synthase.

Where is ATP synthase located in the chloroplast?

The chloroplast adenosine triphosphate (ATP) synthase is located in the thylakoid membrane and synthesizes ATP from adenosine diphosphate and inorganic phosphate at the expense of the electrochemical proton gradient formed by light-dependent electron flow.

Where is the electron transport chain located in photosynthesis?

In photosynthetic eukaryotes, the electron transport chain is found on the thylakoid membrane.

Where are proteins located in prokaryotic cells?

Cytoplasm and Cell Structures

Inside the plasma membrane of prokaryotic cells is the cytoplasm. It contains several structures, including ribosomes, a cytoskeleton, and genetic material. Ribosomes are sites where proteins are made. The cytoskeleton helps the cell keep its shape.

Where is the electron transport chain located in prokaryotes?

The electron transport chain of aerobically respiring prokaryotic and eukaryotic cells is found across the cytoplasmic membrane.

Where in a prokaryotic cell does the electron transport chain reside?

The cytoplasmic membrane is the location of electron transports systems in prokaryotes.

How do electrons get to the electron transport chain?

All of the electrons that enter the transport chain come from NADH and FADH 2​start subscript, 2, end subscript molecules produced during earlier stages of cellular respiration: glycolysis, pyruvate oxidation, and the citric acid cycle.

Where do protons become concentrated in the mitochondria?

Intermembrane space of mitochondria

This process pumps protons (H⁺) into the intermembrane space. The gradient created (high concentration of protons in the intermembrane space and low concentration in the matrix) causes protons to flow through ATP synthetase in the inner membrane resulting in production of ATP.

Where is the protein gradient in photosynthesis?

The light energy is used to separate an electron from PSII, starting its cascade through the electron transport chain. Accompanying the electron transfer, a proton gradient across the thylakoid membrane is established, with a higher concentration of protons and lower pH in the thylakoid lumen.
