Carrier Proteins transport molecules from an area of higher concentration on one side of the membrane to an area of lower concentration on the other side.

∙ 14y agocarrier proteins binds to a specific substance on one side of the cell membrane. this binding causes the protein to change shape. as the protein's shape changes, the substance is moved across the membrane and is released on the other side.

How do carrier proteins transport substances across membranes?
They control what enters and exits the cell :)
How do transport move substances across membranes?
Transport proteins change shape, much like a folding door
Which part allows or prevents substances to go into and out of the cell?
The cell membrane acts as the barrier and transport proteins present in the membrane, such as globular proteins, transport molecules across cell membranes.
Which molecules help control movement of substances through cell membranes?
proteins help control movement of substances through cell membranes.
What cell organelles sorts processes and packages proteins as well as the membranes of transport vesicles?
The Golgi apparatus sorts, processes, and packages proteins as well as the membranes of transport vesicles.
What protein group includes carriers and channels?
Transport Proteins
What form do proteins need to be in to go through the electron transport chain?
Stripped of their electrons by electron carriers. Electrons are the only thing going through the electron transport chain, where their motive force is moving protons across membranes.
How do transport proteins move substances across membranes?
Facilitated diffusion (also known as facilitated transport or passive-mediated transport) is a process of passive transport, facilitated by integral proteins. Facilitated diffusion is the spontaneous passage of molecules or ions across a biological membrane passing through specific transmembrane integral proteins. The facilitated diffusion may occur either across biological membranes or through aqueous compartments of an organism.*This is from Wikipedia.....
What is the function of a transport protein?
Transport protein provide channels for certain solutesTransport proteins are embedded in cellular membranes. They permit the passage across the membrane of substances that cannot pass through the phospholipid bilayer.Substances may pass through transport proteins by diffusion (often called facilitated diffusion because these substances cannot pass through any other part of the membrane) or by active transport.Transport proteins are subdivided into categories, such as channel proteins and carrier proteins, depending on details of their functioning.

How do carrier proteins recognize substances to transport in active transport?
substance to pass
Do some membranes have proteins with chanels that allow for the passage of hydrophilic substances?
true
