Structure in a cell membrane that help particle to move in and out the cell during active transport are made of what?
The structures in a cell membrane that facilitate active transport are primarily composed of proteins, specifically membrane transport proteins or pumps. These proteins can include carrier proteins and channel proteins, which use energy, often in the form of ATP, to move particles against their concentration gradient. This process is essential for maintaining the cell's internal environment and enabling the transport of nutrients and ions.

What is the different between active transport and passive transport of molecules across the cell membrane?
In an active transport, the cell uses energy (ATP) to transport the particle into the cell. Also, the particle moves through a "hallway" type thing. In a passive transport, the cell does not need energy (ATP) to transport the particle into the cell. Also, the particle just bursts through the cell membrane to get inside.
When a cell uses energy to transport a particle through the cell membrane to an of higher concentration the cell is using?
Active transport
What is it called when molecules uses energy to move across a semipermeable membrane?
Active transport
What characteristic makes the cell membrane selectively permeable?
Passive and active transport. Passive transport doesn't require the cell's energy, while active transport does.
What are the types of particle transport how particles move into and out of the cell?
The types of particle transport mechanisms by which particles move into and out of the cell are diffusion, osmosis, and active transport.

What protein binds to a particle and uses energy to move through the cell membrane?
active transport
What is the protein that binds to a particle and uses energy to move through the cell membrane?
Active transport:)
What uses protein binds to a particle and uses energy to move through the cell membrane?
active transport
How does a large particle leave a cell by a active transport?
It requires energy, and a protein carrier molecule. The large particle binds to the protein carrier on the inside of the cell. It is then transported across the membrane as a result of a conformational change in the protein (think of it flipping), and then it is released on the outside of the cell. Again, this requires some source of energy.
What structure allow small particles to cross cell membrane?
Osmosis.
What structure does oxygen diffuses through but sodium ion may need active transport?
A semipermeable membrane
What structure does oxygen diffuse through that a sodium ion may need active transport?
A semipermeable membrane
What is it called when molecules uses energy to move across a semipermeable membrane?
Active transport
Which type of transport requires assistance from membrane proteins?
Active transport requires assistance from membrane proteins. These proteins, such as ion pumps and carrier proteins, help move molecules against their concentration gradient, requiring energy input to drive the process.
The transport of a substance across the cell membrane against its concentration gradient is called what?
The transport of a substance across the cell membrane against its concentration gradient is called active transport.
