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.
What else can I help you with?
Why can oxygen diffuse across a cell membrane but a protein?
Its too large
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.
Which type of transport occurs when a membrane protein binds to a molecule on one side of the cell membrane and then releases it on the other side?
Facilitated diffusion occurs when a membrane protein binds to a molecule on one side of the cell membrane and then releases it on the other side. This type of transport does not require energy and relies on the concentration gradient to move molecules 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.
Why can oxygen diffuse across a cell membrane but a protein cannot-?
Proteins are to large or Oxygen is much smaller than a protein.
What uses a protein to move a molecule across a membrane without energy?
Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.
What used a protein to move a molecule across a cell membrane without energy?
Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.
What is is when a molecule moves across a membrane through a protein channel without using energy?
Passive Transport
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.
What is it called when molecule moves across a membrane through a protein channel without using energy?
Passive Transport
What is it called a molecule moves across a membrane through a protein channel without using energy?
Passive Transport
What is it called when a molecule moved across a membrane through a protein channel without using energy?
Passive Transport
What is it called when a molecule moves across a membrane through a protein channel without using energy '?
Passive Transport
How do carrier proteins transport substance across the membrane?
The carrier protein changes shape , shielding the molecule from the interior of the membrane.
When a protein helps a molecule across the membrane is?
the processe is called osmosis Try again, this time use the term "facilitated transport" since a protein molecule is helping.
What are the steps of facilitated diffusion?
Facilitated diffusion involves the movement of molecules across a cell membrane with the help of transport proteins. The steps include the binding of the molecule to the specific protein, conformational changes in the protein to carry the molecule across the membrane, and the release of the molecule on the other side of the membrane. This process does not require energy input from the cell.
What molecule is used to transport oxygen and act as an enzyme and transport materials across the cell membrane and forms the filaments of muscles?
Protein.
