Question

Explain about transport happening across cell memberane? ( explain it in brief)

Answer 1

Simple diffusion is pretty much exactly what it sounds like – molecules move down their gradients through the membrane. Molecules that practice simple diffusion must be small and nonpolar*, in order to pass through the membrane.arger molecules, such as glucose, need help by way of a transport protein to help carry glucose into a cell and this requires no energy. I hope it helps u

Primary Active Transport: H+, Na+, Ca+2 all utilize ATP to force these things across the membrane.  There is one major distinction between active transport and facilitated diffusion other than one needing energy and the other not
