Channel 1) Allow ions to flow down electrochemical gradient 2) Move ions across membrane very quickly (i.e., million ions/sec) 3) Needs no more than a single gate to control opening. 4) Can be selective for multiple ion types 5) Large domain movement is required to open or close gate(s). (conformational change) 6) Some gates are controlled by smaller structural change (ie. A single amino acid change) 7) Multiple transmembrane domain 8) Can be open to both sides of the membrane
Transporter 1) Move at least one of the ions it is transporting against its electrochemical gradient 2) Slower ions transporter than channels 3) Requires at least two gates to control opening. 4) Can be selective for multiple ion types 5) Large domain movement is required to open or close gates (conformational change) 6) Some gates are controlled by smaller structural change (i.e., A single amino acid change) 7) Must use some form of energy to move ions against its electrochemical gradient. 8) Multiple transmembrane domain 9) Virtually never open to both sides of the membrane Source: 1) http://www.nature.com/nature/journal/v427/n6977 /full/427795a.html
Channel proteins facilitate the passive movement of molecules across cell membranes by creating a pore or channel for them to pass through. Carrier proteins, on the other hand, actively transport molecules by binding to them and undergoing a conformational change to move them across the membrane.
Yes, facilitated diffusion requires a carrier or channel protein for the movement of molecules across the cell membrane.
PROTEIN!!!!!!!!!!!!!!!!!!!!!!!!!
Yes, carrier proteins are also known as carrier molecules or transport proteins. They facilitate the movement of molecules across cell membranes by binding to specific substances and transporting them across the cell.
Exocytosis uses carrier proteins to transport molecules out of the cell. These carrier proteins facilitate the fusion of transport vesicles with the cell membrane, enabling the release of molecules outside the cell.
what is the difference between the ocean the sea and a sea channel
the difference between channel and medium is that channel is the form how the message will be while medium is the actual message

differenve between frequency management and channel assignement
MCT2E (Monocarboxylate Transporter 2E) and HCN-R200 (a specific type of hyperpolarization-activated cyclic nucleotide-gated channel) serve different functions in cellular physiology. MCT2E is primarily involved in the transport of monocarboxylates like lactate and pyruvate across cell membranes, playing a crucial role in metabolic processes. In contrast, HCN-R200 is a channel that facilitates ion flow, particularly sodium and potassium, contributing to the regulation of neuronal excitability and heart rhythm. Thus, their primary difference lies in their roles: one is a transporter involved in metabolism, while the other is an ion channel influencing electrical signaling.

The difference between 150 and 350 digital channel feed in the cable TV lies with the quality of the video.
a straight is narrow body of water, and a channel is a wider body of water.
depends on the transporter. They can travel by air to Roissy airport were there is a big FedEx platform, by train via the Chunnel, by lorries on the channel ferries.
Nothing... 'The Weather Channel' - is the title of the company... weather.com is their website name.
A rill is a much smaller channel. From Sabreena :)
It varies by carrier
