What would happen if molecules couldn't pass through a cell membrane by passive transport?

It would have to pass through the membrane by means of active transport.


What transport may need to use energy to pass through cell membrane?

active transport


What is an Example of active transport?

An example of active transport is sugar molecules going into a cell. It cannot pass right through like water and oxygen so it uses active transport.Diffusion


What type of molecule embedded in the cell membrance allows larger molecule to pass through the membrance by active transport?

Transport proteins allow the active transport of large molecules through the cellular membrane.


What separates active transport from passive transport?

Active transport is when a cell needs to use energy in or to let substances pass in through or out or its cell membrane or cell wall. Passive transport requires to energy at all making substances like water easy to let pass through.


What is the difference between pass and active transport?

Pass transports require no energy and active requires energy. Osmosis is when it travels through water.


What are 3 ways materials can pass through the cell membrane?

Active transport, diffusion, osmosis. Active transport requires energy, but diffusion and osmosis do not.


What occurs if substances are too large to pass through the cell membrane by active or passive transport?

passive transport


Why does active transport happen?

active transport happens like across the membrane. the plant cell membrane is highly selective it allows only some molecules to pass through. for others to pass using energy through specialised proteins they are pumped... active transport even takes place against a concentration gradient.


Name the 2 ways that materials can pass through the cell membrane?

The two ways that materials can pass through the cell membrane are active transport and passive transport. In active transport the molecules cannot pass freely across the membrane and have to be carried across in ways that require energy. In passive transport the molecules can pass freely across the membrane in ways that do not take any energy.


How is faciliated transport similar to active transport?

Both facilitated transport and active transport require the substance that passes the membrane to pass through intermembrane proteins. However, unlike active transport, facilitated transport does not require ATP because it is not actively going against the concentration gradient.


What is large particles that may need to use energy to pass through cell membranes called?

Its passive transport not active because active transport does NOT use energy


What is it called when materials move through a cell membrane without using energy?

Passive transport does not use energy to pass through a cell membrane. active transport uses energy to pass through a cell membrane.


Is plasmolysis active transport?

No, plasmolysis is not active transport it is passive transport through filtration.


Does passive transport requires active transport?

no, because in passive transport, particles pass straight through the cell membrane without the cell using atp


How do substances get in and out of a cell if they are to big to pass through the cell membrane?

Do you mean how do substances move through a cell membrane if they are too big to transport by passive transport?If so, a cell uses active transport to move large particles in and out of a cell. Active transport includes endocytosis, pinocytosis, and phagocytosis.


What is the opposite of active transport?

the opposite of active transport is passive transport, transport of the cell not requiring energy. The plasma membrane acts as a sieve and allows small particles to pass through while restricting the movement of larger ones, for example osmosis.


What are the six processes by which materials pass through cell membranes?

What are the special structures in a cell membrane that allows materials to pass through?

The cell membrane does, through active transport or diffusion.The selectively permeable phospholipid bylayer regulates this.Membrane transport protein.transport proteins


Transport across cell membrane- types of transport?

cell membrane is a lipid bi-layer which allows only fat soluble sunstances to pass through and the remaining essential materials pass with the help of carrier protien..so on this basis the transport is of two types(1) active transport: Active transport uses energy(2) passive transport : does not use any energycheck it out : active-transport


What assists the movement of polar molecules across the membrane A. Passive Transport B. Active Transport?

Polar molecules must pass through the membrane via active transport. This is because the cellular membrane is mostly nonpolar, and polar and nonpolar molecules repel each other. Only nonpolar molecule (i.e. hormones) can pass through the membrane without active transportation.


Give examples of molecules that pass through membranes via active transport?

Ions, Large Polar Molecules


Why are membrane proteins necessary for active transport?

Because not all molecules that are necessary to the cell can pass through the membrane.


How do carrier proteins recognize substances to transport in active transport?

substance to pass


What is active transport through cell membranes?

what must be use along with a transport proteins to move a substance through a cell membrane in active transport
