Question

Which of the following correctly identifies active transport?

A. Transport proteins move large molecules from areas of low.
B. Transport proteins move large molecules from areas of low concentration areas of high concentration areas without the use of cellular energy.
C.Small molecules move from areas of high concentration to areas of low concentration using cellular energy to enter a cell.
D. Small molecules move from areas of low concentration to areas of high concentration without cellular energy to enter a cell.

Please help I think its B.

Answer 1

Did you ever find out the answer?
I need help on this question and 3 others

Answer 2

If you are in Connexus watch the "Brain pop movie," and it will help you understand it. If not I will post the answers later.

Answer 3

Active transport is usually associated with accumulating high concentrations of molecules that the cell needs, such as ions, glucose and amino acids. If the process uses chemical energy, such as from adenosine triphosphate (ATP), it is termed primary active transport.

Answer 4

1. D - Transport proteins move large molecules from areas of low concentration to areas of high concentration using cellular energy.
2.A- Transport proteins move large molecules from areas of low concentration to areas of high concentration using cellular energy.
3.D- Osmosis refers specifically to the diffusion of water.
4.B- from areas of higher concentration to areas of lower concentration.
5.B- exocytosis.
