What is the difference between a pump and a vesicle?

A pump is a carrier protein that uses energy to carry substances against their concentration gradient. A vesicle is a membrane-bound sac. That is the difference between these two.

A pump is a carier protein that requires energy to pump substances against their concentration gradient. A vesicle is a membrane bound sac.

Well a pump is a carrier protien that uses to carry matter agaisnt the concentration gradient. And then there a vesicle that is as memberand-bound sac thing..

A pump carries substances against their concentration gradient. Vescles carry substances too large through the membrane. Thats the difference.

A pump is a carrier protein that uses energy to carry substances. They carry them against their concentration gradient. A vesicle is a membrane-bound sac.

A pump uses energy to carry substances aginst their concentrtion in active transport. a vesical is a membrane bound sac. A pump pumps what the vesical has to store.

There is a difference between a pump and a vesicle. A vesicle is a small cavity or sac that contains materials in a eukaryotic cell. A pump is a carrier protein that uses energy to pump substances against their concentration gradient.

A pump pumps substances againist their gradient. WHile a they carry large substances through the membrane.

A pump is a carrier protein that uses energy to move substances agains their concentration gradient. A vesicle is a membrane bound sack. So, they are very different.

A pump is an active transport process use carrier proteins to move substances against their concentration gradient. A vesicle is a membrane bound sac.

Jon said...

a pump is an active transport process where they used carrier protiens to more substances. and a vesicle is a bud off of the membrane, fuse within, or fuse without other vesicles. memebrane bound sacs.

A vesicle is a membrane-bound sac. A pump is a carrier protein that uses energy to carry substances against thier concentration gradient. So thats the differences!

A vesicle is a membrane bound sac. A pump is a carrier protein that uses energy to carry substances against their concentration gradient of course.

Mitchell Haaland said...

a pump carries proteins and a vesicle is just a sac...so there ya go!

Fuhrman#34 said...

Pump- carrier proteins do requier energy to "pump substances against their concentration gradients
Vesicles- membrane-bound sacs

A pump is a carrier protein that uses energy to pump substances against their concentration gradient, which is why they call them pumps. A vesicle is just a membrane-bound sac.
