What else can I help you with?
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.
The movement of substances through a cell membrane without the use of cell energy?
Passive transport using osmosis and diffusion. Osmosis only applies to the movement of water down a concentration gradient across a selectively permeable membrane. DOH!!!
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 cell membrane, also known as the plasma membrane, is responsible for regulating the movement of water and substances through processes like active transport and passive transport. It acts as a selectively permeable barrier, allowing certain molecules to pass through while blocking others.
Is transport through aquaporin passive or active?
Transport through aquaporins is passive, as water molecules move across the cell membrane through these channels driven by osmotic gradients without the need for energy expenditure.
What makes passive transport passive?
Passive transport is called passive because it doesn't require chemical energy intervention to occur. The four main types of passive transport are diffusion, facilitated diffusion, osmosis, and filtration.
The passive transport of water through a membrane is?
Osmosis
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.
What occurs if substances are too large to pass through the cell membrane by active or passive transport?
passive transport
The movement of substances through a cell membrane without the use of cell energy?
Passive transport using osmosis and diffusion. Osmosis only applies to the movement of water down a concentration gradient across a selectively permeable membrane. DOH!!!
Is diffusion an example of active transport or passive transport?
Diffusion is an example of passive transport, like osmosis(the diffusion of water through a membrane).
What types of molecules get through the membreane with passive transport?
Small, non-polar molecules like oxygen and carbon dioxide can pass through the cell membrane via passive transport. Additionally, some small polar molecules like water can also use passive transport mechanisms such as facilitated diffusion to cross 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 cell membrane, also known as the plasma membrane, is responsible for regulating the movement of water and substances through processes like active transport and passive transport. It acts as a selectively permeable barrier, allowing certain molecules to pass through while blocking others.
What is the pasive transpart of water through a membrane called?
The passive transport of water through a biological membrane is called osmosis.
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 is the opposite of pasive?
If you mean the opposite of passive transport, like through a membrane, the opposite is active transport.
Is transport through aquaporin passive or active?
Transport through aquaporins is passive, as water molecules move across the cell membrane through these channels driven by osmotic gradients without the need for energy expenditure.
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.
