C. Gases
Solids and liquids have very little space in between particles, meaning that it is hard to push the particles even closer.
Gas particles are spread apart and can be pushed together since there is more space for the air to be taken up.
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.
Answer:
Viruses are tinier than bacteria. In fact, the largest virus is smaller than the smallest bacterium. All viruses have is a protein coat and a core of genetic material, either RNA or DNA. Unlike bacteria, viruses can't survive without a host.
So life itself is an emergent, complex state, but it is made from the same fundamental, physical building blocks that constitute a virus. Approached from this perspective, viruses, though not fully alive, may be thought of as being more than inert matter: they verge on life.
