Facilitated diffusion is the type of transport that occurs when membrane proteins bind to a molecule on one side of the cell membrane and then releases it on another side. An integral membrane protein provides continuous protein lined pathway through bilayer. There are two classes of proteins transport membrane one which carries specific molecules across and two is channel proteins which form narrow pore where ions can pass.
Channel proteins also carry out passive transport where ions level spontaneously down their gradients membranes which transport proteins are important pharmacologically with two reasons. One is some drugs exploit endogenous membrane transport process to enter or exit cells. Two membrane transport proteins are major drug targets.
Facilitated diffusion or facilitated transport is also known as passive-mediated transport is the movement of molecules or ions across a biological membrane through transmembrane integral proteins. This process does not require chemical energy from ATP as such molecules and ions use the movement of gradient concentration for diffusion.
False. Tropical rain forests and coral reefs each have many different species living among them. Therefore, They would have a high biodiversity. Hope this helps!
The molecular clock is a scientific technique which presents a means of estimating evolutionary rates and timescales using genetic data. It uses mutation rate of biomolecules when two or more life forms diverged to estimate the time. Answer is B.
The blackberry is an example of an aggregate fruit. These are made by the merger of several ovaries, while simple fruit is made by just one. Other fruits from this fruit type are raspberry and dewberry.
