Answer
The ATP molecule is necessary in this type of transport due to the particles are moving against the concentration gradient.
Explanation:
ATP is needed for many functions that require energy, and one of them is active transport across the cell membrane.
Unlike passive transport, where particles move along the concentration gradient, active transport -which uses the energy of ATP- is characterized by mobilizing particles against the concentration gradient.
The cell membrane is semi-permeable, so some substances cannot pass freely, requiring transporters to be able to pass through it.
Other options are not true for:
<em> A. A charged particle can move through a channel specific to it.
</em>
<em> C. There is no particle entrapment in the plasma membrane.
</em>
<em> D. Particles do not move in favor of a concentration gradient.</em>
