What change takes place in the cell membrane if a signal molecule causes a transport protein to open?
When a signal molecule activates a transport protein on the cell membrane, it undergoes a conformational change that opens a channel or alters its affinity for the molecule it transports. This allows specific substances to move across the membrane, facilitating cellular communication and maintaining homeostasis.
What type of transport requires energy move a molecule?
Active transport requires energy to move a molecule.
What uses a protein to move a molecule across a cell membrane without using energy?
Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.
The use of energy to move substances across a cell membrane describes?
Active transport, which requires energy in the form of ATP to move substances against their concentration gradient across a cell membrane. This process involves specific protein pumps that bind to the molecule being transported, consuming ATP to change conformation and move the molecule across the membrane.
How do carrier protiens transport substances across cell membrane?
Carrier proteins facilitate the transport of substances across the cell membrane by binding to the specific molecules they transport and undergoing conformational changes to move the molecules across the membrane. This process is often referred to as facilitated diffusion. It allows for the transport of specific molecules, such as glucose or ions, across the membrane, down their concentration gradient.
What type of transport occurs when a membrane protein binds to a molecule on one side of the cell membrane then releases it to the other side?
facilitated diffusion
Which type of transport occurs when membrane protein binds to a molecule on one side of the cell membrane and then releases it on the other side?
facilitated diffusion is the type of membrane that occurs in protein binds. This is when molecule goes to one side.Edit : fixed the wrong answer

What happens if a molecule is too large to go through a membrane?
The molecule will be transported across the membrane by way of a transport protein or protein channel.
How are proteins arranged in a plasma membrane and the part that they play in transporting substances into and out of cells?
Think of Active Transport!! Protein grabs molecule Protein rotates round Protein releases molecule Protein rotates round again But this requires energy, so alot of mitochondria are required, and also active transport goes against the concentration gradient.
How do carrier proteins transport substance across the membrane?
The carrier protein changes shape , shielding the molecule from the interior of the membrane.
