What type membrane proteins are integral proteins that moves ions or molecules across plasma membrane?
Integral membrane proteins that move ions or molecules across the plasma membrane are primarily categorized as transport proteins. These include channel proteins, which create passages for specific ions or molecules to flow through, and carrier proteins, which bind to specific substances and undergo conformational changes to transport them across the membrane. Both types are crucial for maintaining cellular homeostasis and facilitating communication between the cell and its environment.
Occurs when the plasma membrane surrounds a large substance inside the cell and moves it outside the cell?
exocytosis
What is it when water moves across a cell membrane?
When water moves across a cell membrane, it is called osmosis. Osmosis is the passive movement of water molecules from an area of higher concentration to an area of lower concentration through a selectively permeable membrane.
How does oxygen with a lower concentration inside a cell than outside the cell move across the plasma membrane?
Oxygen moves across the plasma membrane from an area of higher concentration (outside the cell) to an area of lower concentration (inside the cell) through a process called diffusion. This movement occurs because oxygen is a small, nonpolar molecule that can easily pass through the lipid bilayer of the membrane. Additionally, the concentration gradient drives the diffusion until equilibrium is reached.
What does the neurotransmitter bind to after it moves across the synaptic cleft?
The neurotransmitter binds to specific receptors on the postsynaptic neuron's membrane. This binding triggers a series of events that can either excite or inhibit the postsynaptic neuron, ultimately influencing its activity.
What moves marerials across the plasma membrane in the direction of the concentration?
Active transportation is the material that across plasma membrane. This makes it flow one way.
Which transport mechanisms moves materials across a plasma membrane against an apparent concentration gradient?
active transport
A non-energy requiring process that moves materials across a cell membrane with the concentration gradient.?
Passive transport is a non-energy requiring process that moves materials across a cell membrane with the concentration gradient. This process includes simple diffusion, facilitated diffusion, and osmosis.
What is the name for the movement of water access the plasma membrane?
The movement of water across the plasma membrane is called osmosis. Water moves from where it is in higher concentration to where it is in lower concentration. Osmosis is a type of passive transport and does not require any energy expenditure by the cell.
What is it called that controls what moves in and out of the cell cytoplasm?
Cell membrane controls it.Also called the plasma membrane.
What type membrane proteins are integral proteins that moves ions or molecules across plasma membrane?
Integral membrane proteins that move ions or molecules across the plasma membrane are primarily categorized as transport proteins. These include channel proteins, which create passages for specific ions or molecules to flow through, and carrier proteins, which bind to specific substances and undergo conformational changes to transport them across the membrane. Both types are crucial for maintaining cellular homeostasis and facilitating communication between the cell and its environment.
Involves water moving across the plasma membrane to the side with the greater solute concentration?
Osmosis is the process where water moves across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration. This movement aims to equalize the concentration of solutes on both sides of the membrane.
What helps moves things across the membrane?
transportation
Which one moves faster across the cell membrane the large or the small?
Small particles move faster across the membrane.
Occurs when the plasma membrane surrounds a large substance inside the cell and moves it outside the cell?
exocytosis
What occurs when the plasma membrane surround large substance inside the cell and moves it outside the cell?
exocytosis
How does the material move from the respiratory system to the circular system?
Material moves from the respiratory system to the circulatory system by diffusing across a membrane in the air sacks called alveoli.
