Because cells are not islands unto themselves. They need to rid themselves of wastes and take in food, oxygen, and other raw materials to maintain their cellular activities.

What biomolecule helps transport molecules across the membrane?
proteins
Does active transport get substances across a cell membrane?
Transport proteins
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.
How is water transported across the membrane?
Water is transported by a passive transport called osmosis. Osmosis is diffusion of water across the membrane.
A type of passive transport across a cell membrane that requires special carriers is?
Active transport
What is the transport of water across the cell membrane called?
Movement of water across a membrane is called OSMOSIS.
What biomolecule helps transport molecules across the membrane?
proteins
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.
What is the movement of water across a membrane?
Active transport
What is the movement of water across the membrane?
Active transport
What is meant by passive transport of material across a membrane?
"Passive" mean that it does not require energy, therefore the passive transport of material across the membrane means that it can transport the material (cells or whatever) without the function of energy across the membrane.
How plasma membrane diffuse across plasma membrane?
Ions can't diffuse across membranes, they must used channels to transport across
What are the types of membrane transport across the cell membrane require a protein carrier?
The brain
Does active transport get substances across a cell membrane?
Transport proteins
What two forces drive the passive transport of ions across a membrane?
Two forces drive the passive transport of ions across a membrane: -the concentration gradient of the ions -the effect of membrane potential (voltage) on the ions
What kind of transport across membrane does not require energy?
Ghh
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.
