What is the most acidic part of the electron transport chain?

The most acidic environment, or the lowest pH, would be found in the intermembrane space. This is because as and pass their electrons to the enzymes in the electron transport chain, protons are pumped into the intermembrane space. This is where a high concentration protons is generated, which is considered acidic.

Where in the mitochondria is more acidic?

Higher proton concentration means more acidic. Thus the space between the two membranes, where the protons are concentrated by the electron transport system would be the most acidic.

Is the intermembrane space more acidic than the mitochondrial matrix?

Explanation: ATP synthase, which is located on the inner mitochondrial membrane, requires a proton gradient in order to create ATP. This results in the intermembrane space having the lowest pH in the mitochondria, due to the high proton concentration.

Is the intermembrane space of mitochondria acidic?

The pH of the intermembrane space is about 7.0, whereas the pH of the matrix is about 8.0.

What does the electron transport chain acidify?

The electron transport chain is a series of proteins embedded in the inner mitochondrial membrane. Finally, the electrons are passed to oxygen, which accepts them along with protons to form water. The proton gradient produced by proton pumping during the electron transport chain is used to synthesize ATP.

Which part of the mitochondria has the highest concentration of protons?

intermembrane space
The highest proton concentration occurs in the intermembrane space inside the mitochondria.

Where is the electron transport chain located in the mitochondria?

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.

Which region of mitochondria has the highest H+ concentration?

The H+ concentration is highest in the intermembrane space of the mitochondria.

How is pH affected by electron transport chain?

After cyanide poisoning, the electron transport chain can no longer pump electrons into the intermembrane space. The pH of the intermembrane space would increase, the pH gradient would decrease, and ATP synthesis would stop.

What is electron transport system in mitochondria?

The electron transport chain in the mitochondrion is the site of oxidative phosphorylation in eukaryotes. The NADH and succinate generated in the citric acid cycle are oxidized, which provides energy to power ATP synthase. Photosynthetic electron transport chain of the thylakoid membrane.

In which compartment of the mitochondria is the proton concentration higher with an active electron transport chain?

The transport chain builds a proton gradient across the inner mitochondrial membrane, with a higher concentration of H +start superscript, plus, end superscript in the intermembrane space and a lower concentration in the matrix.
