Science TRIVIA!!?

Question

Explain Passive Transport & Active Transport.
Best answer gets 5 stars best answer.

Answer 1

Passive transport is like a barge that's floating down the river - it doesn't really need engines, except to come back.

Active transport is something that has to burn energy in order to move, like a barge going UP river, or a car.

Answer 2

In the non scientific definition.
Active Transport is when you take your butt off the couch and actually get up to change the channel when the battery in the tv remote is dead.
Passive transport is actually you pressing the button harder to see if that will work and change the channels.


Scientific definition
Active transport is the movement of materials through a cell membrane using energy,the mediated transport of biochemicals, and other atomic/molecular substances, across membranes. Unlike passive transport, this process requires chemical energy. In this form of transport, molecules move against either an electrical or concentration gradient

Passive transport is a means of moving biochemicals, and other atomic or molecular substances, across membranes. Unlike active transport, this process does not involve chemical energy. Passive transport is dependent on the permeability of the cell membrane,
Examples of passive transport include
·Simple diffusion
·Channel diffusion
·Facilitated diffusion

Answer 3

One difference between them is that Passive Transport happens spontaniously and Active Transport needs energy to happen.
Hope this helps
