What are transport electrons?

What are transport electrons?

The electron transport chain is a series of proteins embedded in the inner mitochondrial membrane. In the matrix, NADH and FADH2 deposit their electrons in the chain (at the first and second complexes of the chain, respectively).

What is the process of transporting electrons called?

The redox reactions that remove electron pairs from glucose transfer them to small molecules called electron carriers. The electron carriers deposit their electrons in the electron transport chain, a series of proteins and organic molecules in the inner mitochondrial membrane.

What is the function of electron transport system?

The purpose of electron transport is to conserve energy in the form of a chemiosmotic gradient. The gradient, in turn, can be exploited for the phosphorylation of ADP as well as for other purposes.

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.

Where does electron transport occur?

inner membrane
The electron transport chain activity takes place in the inner membrane and the space between the inner and outer membrane, called the intermembrane space.

What is the main goal of the electron transport chain?

The electron transport chain is primarily used to send protons across the membrane into the intermembrane space. This create a proton-motive force, which will drive ATP synthase in the final step of cellular respiration to create ATP from ADP and a phosphate group.

Why is the electron transport chain important?

The ETC is the most important stage of cellular respiration from an energy point of view because it produces the most ATP. When a cell needs energy, it breaks the third phosphate group bond and uses the resulting energy.

What is cyclic electron transport and why is it important for photosynthesis?

The light reactions in photosynthesis convert light energy into chemical energy in the forms of ATP and NADPH. The role of cyclic electron transport around PS I is proposed to be essential for balancing the ATP/NADPH production ratio and/or for protecting both photosystems from the damage via stromal over-reduction1.
