Active transport can occur against a diffusion gradient ("uphill flow).
No, actually diffusion is a kind of passive transport, and osmosis is a kind of diffusion. Any passive transport can happen without energy (contrary to active transport). Since, all the things you listed were passive transport, they happen down the concentration gradient and need no ATP.
active, passive transport, maybe osmosis too I'm not sure
yes, kinetic energy is used in passive transport
It is because active transport requires energy for it to work.
Fiber optic couplers can be either active or passive devices. The difference between active and passive couplers is that a passive coupler redistributes the optical signal without optical-to-electrical conversion. Active couplers are electronic devices that split or combine the signal electrically and use fiber optic detectors and sources for input and output.
Active transport requires energy while passive transport does not.
yyou momm a is ugly
Passive transport and active transport are transport of materials across membranes. Passive requires no energy, while active does.
In passive transport the solute is driven across the cell until both sides of the membrane are equal. In active transport, energy causes the transporter to release the solute to only one side of the membrane.
Active transport requires energy; passive transport does not.
Active transport requires energy; passive transport does not.
passive
passive
it is an ACTIVE transport.
Active transport requires energy, passive transport does not.
It has is in the name. Active Transport
Passive Transport, i think.
