PLEASE HELP (answer which ever one of the few are listed that you can!) 1. Is it in passive or active transport that ions such as Na+ and K+ are being moved?

2. Are large molecules moved in active or passive transport?

3. Is it in active or passive transport where small nonpolar and polar molecules are being moved?

4. Do molecules pass between the phospholipids in active or passive transport?

5. Are molecules being pumped against or along the concentration gradient in active transport?

Explanation:

Keep in mind active transport is always against the concentration gradient.

For active transport pumps or chaanel protiens needed so if these are pasaing through phospholipids than most probably it is passive transport.

Listen dear it is it is more important that movement is along or against the concentration gradient than what is moving if it is along concentration gradient than it is passive and if against gardient it is active

Simple to remember is energy ATP is used active other wise passive .

what are the options? add them, then i will be glad to .
