Dinitrophenol (2,4-DNP) destroys proton gradients without affecting anything else about a membrane. Its pKa slightly acidic, so it can be protonated or unprotonated in cells.a. What would be the effect of adding dinitrophenol to the mitochondrial inner membrane

Answers

Answer:

the effect of adding dinitrophenol to the mitochondrial inner membrane is -:

Production of ATPNo electron transferproduction of more sugar as energyUncoupling of ETC(electron transport chain)

Explanation:

Dinitrophenol is an uncoupler which can isolate the progression of electrons and siphoning of H+ particles for ATP Synthesis. On adding the dinitrophenol, the energy from the electron move can't be utilized for ATP blend. It has been utilized in diet pills and as a counting calories help. It goes about as protonophore and permits spillage of the protons through the internal mitochondrial layer which subsequently sidesteps ATP synthase and consequently the creation of ATP creation gets wasteful. It hinders the ATP synthase and thus its capacity to deliver ATP. It likewise influences the ETC in light of the fact that forestalls development of electrons over the ETC. Uncoupling the ETC would prompt diminished ATP creation and consequently increasingly more sugar is used as energy. This would restrict accessibility of ATP and make a deadly circumstance.

Explain the process that creates wind.

Answers

Answer:

Winds are caused by differences in air pressure. Unequal heating of Earth’s surface creates areas of different pressure. Cooler areas have higher air pressure. Warmer areas have lower pressure. This causes air to move from high pressure to low pressure. This movement is the wind we feel.

Answer:

Wind is air in motion. It is produced by the uneven heating of the earths surface by the sun. since the earths surface is made of a various land and water formations, it absorbs the sun's radiation unevenly. Two factors are necessary to specify wind which is speed and direction.

What must match between a virus and a host cell?

A)DNA= Cell DNA
B)RNA=ribosome
C)envelope proteins= cell receptors
D)blood types

Answers

Answer:

C)envelope proteins= cell receptors

Explanation:

To enter the cell, the virus must bind to receptor proteins on the cell surface It does so via its envelope proteins. When the receptors and the envelope proteins match, the virus can become engulfed into the cell.

Once it enters the cell, the hijacks the cell's transcription and translation machinery and causes the viral proteins to be expressed. The viral proteins assemble into viral particles. Eventually, the cell bursts and the viral particles are released.
