What is a protein moves molecules across a membrane?
Facilitated diffusion moves molecules through cell membranes passively.
What is the transport that moves a solute down the concentration gradient?
Simple diffusion
What gas moves into or out of cell diffusion?
Oxygen and carbon dioxide move into and out of cells through diffusion. Oxygen diffuses into cells to be used in cellular respiration, while carbon dioxide diffuses out of cells as a waste product of this process.
What is the process that moves particles from areas of high or two areas of lower concentration called?
The process that moves particles from areas of high concentration to areas of lower concentration is called diffusion. During diffusion, particles spread out to achieve an equilibrium, where their concentration is uniform throughout the space. This process occurs naturally and does not require energy input. If the movement involves a selectively permeable membrane, it may also be referred to as facilitated diffusion.
What is the net movement of gases into anf out of a leaf during daytime?
During the daytime, there is a net movement of carbon dioxide into the leaf for photosynthesis, while oxygen and water vapor are released as byproducts of photosynthesis and respiration. This exchange of gases is facilitated by small openings on the leaf surface called stomata.
What is a protein moves molecules across a membrane?
Facilitated diffusion moves molecules through cell membranes passively.
Compare and contrast simple diffusion and osmosis?
osmosis moves through a membrane diffusion moves from higher concentration to lower concentration
What is the transport that moves a solute down the concentration gradient?
Simple diffusion
What moves substances into and out of the cell in facilitated diffusion?
coffee
Where and when does diffusion occur?
Diffusion occurs when there is a concentration gradient i.e. a substance moves from higher to lower concentration.
What gas moves into or out of cell diffusion?
Oxygen and carbon dioxide move into and out of cells through diffusion. Oxygen diffuses into cells to be used in cellular respiration, while carbon dioxide diffuses out of cells as a waste product of this process.
How is diffusion used when cells remove carbon dioxide?
Carbon dioxide moves out of the cells from a higher to lower concentration across the cell membrane. Then the CO2 moves through the capillary wall across the diffusion gradient. The diffusion process is repeated at the capillary/alveolar junction.
What is diffusion of oxygen all about?
Diffusion is the main method by which molecules move across the cell membrane. during diffusion, molecules move from an area of higher concentration, to an area of lower concentration. What is Osmosis? Osmosis is the transport of water from an area of high concentration, to an area of low concentration water moves inside and inside of the cell membrane by osmosis. osmosis is the diffusion of water!
Name the process by which oxygen moves across the wall of the alveolus?
diffusion
In what ways do molecules move?
it moves by diffusion, osmosis and active transport
What is the proccess by which water moves across a cell's membrane?
Passive diffusion.
What are the passive process that moves substances across membranes?
Diffusion ,osmosis
