An energy pyramid is a graphical model of energy flow in a community. The different levels represent different groups of organis

ms that compose a food chain. An energy pyramid’s shape shows how the amount of useful energy that enters each level. Chemical energy, in the form of food, decreases because some is used by the organisms in each level. The source of the chemical energy is the producers, that rearrange carbon dioxide and water in the presence of light to make ________ through the process of ______________.

Describe facilitated diffusion of ions through the channel proteins
Amiraneli [1.4K]

Facilitated diffusion is usually significant to pass the ions across the hydrophobic layer of the plasma membrane. Transmembrane integral protein and careers proteins provide the channels that allow the ion to pass across the membrane.  When an ion bind to their active site on the protein (note that the proteins are very selective), the protein changes conformation. It is this change in conformation opens up the channel that allows the ions to be passed across the membrane. When the ions are released inside of the cell, the protein resumes normal shape (and the channel also closes) and the active site becomes available again or another ion.
