Osmosis is the movement of water (solvent) over a semipermeable membrane - as long as there is a difference in concentrations of osmotically active substances (proteins for instance) on the two sides of the membrane, the water keeps moving to the side where concentration is higher, until there's no longer a difference. Water hence moves freely, passively, from a lower water concentration to a higher one. Active transport usually happens against an electrochemical gradient, i.e. energy (ATP) is used to pump a substance (solute) over a non-permeable membrane from lower to higher concentration. In this case it is the specific substance, not water, that moves over the membrane. The way of movement is different and the transported molecule is different in the two scenarios, but in both cases the molecule moves from a lower to a higher concentration with a membrane separating the two solutions.
What else can I help you with?
What do active transport and osmosis have in common?
Both active transport and osmosis are processes that involve the movement of molecules across a cell membrane. However, active transport requires the use of energy to move molecules against their concentration gradient, while osmosis involves the passive movement of water molecules from an area of high water concentration to an area of low water concentration.
Which statement concerning osmosis and active transport is NOT correct?
The statement that osmosis requires energy input from the cell is not correct. Osmosis is a passive process that does not require energy input from the cell, while active transport does require energy to move molecules against their concentration gradient.
Does osmosis involve transport proteins?
No, osmosis does not involve transport proteins. Osmosis is the passive movement of water across a selectively permeable membrane in response to a concentration gradient. Transport proteins are involved in facilitated diffusion and active transport processes.
Why is osmosis an example of passive transport and not active transport?
passive transport does not require energy eg. diffusion and osmosis. Therefore, osmosis is a passive transport. Active transport requires energy eg. a molecule going from a low concentration from a high concentration.
Diffusion osmosis active transport all of these are methods by which a cell?
Diffusion, osmosis, and active transport are methods by which a cell can move molecules across its membrane. Diffusion is the passive movement of molecules from an area of high concentration to low concentration. Osmosis is the diffusion of water molecules across a selectively permeable membrane. Active transport requires energy to move molecules against their concentration gradient.
How is active transport different from osmosis?
active transport uses energy
How is active transport different from osmosis's?
active transport uses energy
What is Comparison between active transport and osmosis?
active transport requirs energy; osmosis requires very little to no energy
Difference between osmosis and active transport?
The difference between osmosis and active transport is that osmosis takes place only in water molecule and active transport takes place in takes place in the internal lining of the small intestine. 2 osmosis takes place in presence of concentration gradient and active transport against the concentration gradient.
Is diffusion and osmosis both active transport?
no they are passive transport
How does active transport differ from osmosis?
weener!
Is osmosis active or a passive transport?
Passive.
Is sugar osmosis or passive transport or active transport?
Sugar transport can occur through both passive transport, such as facilitated diffusion or simple diffusion, and active transport, such as primary or secondary active transport processes. Osmosis specifically refers to the movement of water across a semi-permeable membrane, so sugar transport itself is not osmosis.
What is active transport in a plant?
a houseplant in dry soil is this process diffusion,osmosis,or active transport
Is osmosis active trasport or passive trasport?
Osmosis is an example of Passive Transport.
What is the difference between active transport and osmosis?
Osmosis is the diffusion of water across a membrane, and does not require the input of energy. Active transport requires energy input.
What do active transport and osmosis have in common?
Both active transport and osmosis are processes that involve the movement of molecules across a cell membrane. However, active transport requires the use of energy to move molecules against their concentration gradient, while osmosis involves the passive movement of water molecules from an area of high water concentration to an area of low water concentration.
