When An ion must cross the cell membrane through active transport instead of passive transport when the ion is?
An ion must cross the cell membrane through active transport instead of passive transport when it is moving against its concentration gradient, meaning it is moving from an area of lower concentration to an area of higher concentration. Active transport requires energy, typically in the form of ATP, to facilitate this movement. This process is essential for maintaining cellular homeostasis and regulating ion concentrations within the cell.
What else can I help you with?
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 you use passive transport in a sentence?
Passive transport is a process in cells where substances move across the cell membrane without requiring energy input. An example of passive transport is the movement of oxygen and carbon dioxide across the cell membrane through simple diffusion.
What type of molecules embebbed in the plasma membrane allows molecules to pass through the membrane by active or passive transport?
proteins
How carbon dioxide water and sodium ions are transported across the cell membrane by both passive and active transport?
Carbon dioxide can diffuse passively through the cell membrane due to its small size and nonpolar nature. Water molecules can pass through the membrane via osmosis, a type of passive transport. Sodium ions are transported against their concentration gradient through active transport processes such as sodium-potassium pumps that require ATP for energy.
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.
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
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 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.
What is the opposite of pasive?
If you mean the opposite of passive transport, like through a membrane, the opposite is 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)
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.
What particles move through cell membrane between phospholipid molecules What transport?
Osmosis, Passive Transport, and Active Transport
How do you use passive transport in a sentence?
Passive transport is a process in cells where substances move across the cell membrane without requiring energy input. An example of passive transport is the movement of oxygen and carbon dioxide across the cell membrane through simple diffusion.
