Answer is D.Because phospholipids form the basic structure of a cell membrane
A proton gradient is an important part of both photosynthesis and cellular respiration because couple the favorable flow of H+ to transport specific metabolites into and out of organelles.
<h3>What is the proton gradient?</h3>
The gradient is sometimes called the proton-motive and can be thought of as a form of energy, force and force in a battery. Like other ions, protons are not able to cross directly through the phospholipid bilayer of the membrane, as the interior of the membrane is hydrophobic.
The proton gradient generated by this manipulation provided a driving force for ATP synthesis in the absence of light. This confirms the chemiosmotic theory, where a chemical potential across the membrane can provide energy for ATP synthesis.
The proton gradient produced by pumping protons during the electron transport chain is used to synthesize ATP.

Light that passes through a polarizing filter is called a vacuum.

Explanation:
The Ritcher scale is a logarithmic scale and it suggests that the number increases by a factor of 10.
One point on the scale differs from another by an order of 10.
- The Ritcher scale is used to measure the magnitude of earthquakes in a particular area.
- It is graduated form 1 to 10
- The magnitude of the quake increases as one moves from 1 through 10.
- This is because the magnitude of the quake actually increases by an order of 10.
