Multiple Choice

 Imagine that you are an ion about to enter a cell. You have to pass through a channel, or sometimes, ask for help from a carrier. What kind of transport are you using?

• Active transport

• Passive transport

Open Ended

Give 3 words to describe the difference between active transport and passive transport.

​Active Transport

​Remember APE:

• AGAINST the concentration gradient

• ​PUMP (vs. channels and carrier proteins)

• ​ENERGY requiring transport (in the form of ATP)

Open Ended

Multiple Choice

Osmosis is a type of diffusion. When we talk about osmosis, which component will pass through the membrane?

• Solute 

• Solvent

​Osmosis

• ​When talking about osmosis, remember the following:

  • ​When referring to concentration, we are talking about the SOLUTE.

  • ​When referring to movement, we are talking about the SOLVENT.

​HYPERTONIC SOLUTION

​This term means there is MORE SOLUTE present in the solution.

​HYPOTONIC SOLUTION

​This term means there is less SOLUTE present in the solution.

​ISOTONIC SOLUTION

​This term means the amount of solute is equal on both sides.

​BOTH SIDES OF WHAT?
