TOPOISOMERASE

There are various function of DNA toposisomerase such as:

1.accessing DNA- this happens during transcription and replication, DNA must be unwound for this to happen, Topoisomerase I make a single break to create an access.

2. Removing DNA super coils- Topoisomerase prevents DNA to be supercoiled, this happens during transcription of DNA to RNA

3. Strand breakage- It can introduce single strand breaks that are required for DNA to be exchanged to adjacent chromosomes.

-Dominant- [34]

Answer:

ATP production: reduced

Proton gradient: Dissipated

pH of the various mitochondrial compartments: pH of matrix will be reduced while that of the intermembrane space will be increased.

Explanation:

During oxidation of FADH2 and NADH, electrons are transferred through electron transport chain to the terminal electron acceptor, molecular oxygen. Electron transfer by the electrons carriers of electron transport chain is accompanied by the pumping of protons from matrix to the intermembrane space and generation of the proton concentration gradient. The proton concentration gradient drives ATP synthesis.

According to the given information, DNP shuttles protons from the intermembrane space into the matrix and thereby, lowers down the pH of the matrix making it more acidic with respect to intermembrane space. This would dissipate the proton concentration gradient and there will be reduced or no ATP production in the absence of the driving force.
