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

What does the passive in passive transport mean?
Passive Transport is the movement of molecules down a concentration gradient from a region of high concentration to a region of low concentration until equilibrium is reached. Some examples are diffusion and osmosis. Basically, it's a movement of molecules across a membrane that doesn't require energy (ATP)
The movement of materials through a cell membrane without using the cells energy?
It's called passive transport for a cell's membrane. (I checked with my science teacher)
What are facts about passive transport?
The transport of molecules across the plasma membrane of a living cell by a process that involves a specific transmembrane carrier
What helps molecules diffuse across membrane through transport proteins?
A process known as passive transport helps molecules to diffuse across a membrane. Passive transport does not involve the use of chemical energy, unlike active transport does.
What type of molecules embebbed in the plasma membrane allows molecules to pass through the membrane by active or passive transport?
proteins
A sentence for the word passive transport?
Passive transport refers to the movement of molecules across a cell membrane. An example of a sentence would be: "Passive transport does not require energy to work".
Is enewrgy required for the movement of water molecules across the cell membrane?
No. Osmosis is a form of passive transport.
What is difference between active transport and passive transport?
One difference is energy consumption. Active transport requires the cell to expend energy, while passive transport does not. Active transport is movement from a lower concentration to a higher concentration and passive transport is movement from a higher concentration to a lower concentration. Active transport is the movement of molecules across a membrane requiring energy to be expended by the cell. Passive transport is diffusion across a membrane requiring only random motion of molecules with no energy expanded by the cell. Active transport requires ATP to transport materials. Passive transport does not require ATP input to transport materials. Ex: diffusion

What is the act of molecules crossing a membrane?
passive or active transport
The movement of materials through a cell membrane without using the cells energy?
It's called passive transport for a cell's membrane. (I checked with my science teacher)
How do carriers proteins facilitate passive transport of molecules across a membrane?
Carrier proteins facilitate passive transport of molecules across a membrane by changing its shape, by using ATP, to allow a substance to pass through the membrane.
What is the name of the membrane that allows the movement of water and substances to move through the process of active transport and passive transport?
The name of the membrane that allows movement of water and substances through the process of active and passive transport is semipermeable membrane.
What is the movement of molecules the input of energy?
The movement of molecules without the input of energy is passive transport.
What are facts about passive transport?
The transport of molecules across the plasma membrane of a living cell by a process that involves a specific transmembrane carrier
What helps molecules diffuse across membrane through transport proteins?
A process known as passive transport helps molecules to diffuse across a membrane. Passive transport does not involve the use of chemical energy, unlike active transport does.
What is it called when the movement of materials through a cell membrane without using the cells energy?
Passive transport does not use energy to pass through a cell membrane. active transport uses energy to pass through a cell membrane.
