Question

Fill in the blank.

Answer 1

Answer: 1: hypertonic

2 -80 millivolts

3 osmosis or osmotic pressure

4 potassium

5. concentration gradient

6 a chemical gradient occurs when more of one molecule is on one side of a membrane, and more of another molecule is on the opposing side. An electrical gradient occurs when more positive or negative ions are on either side of a cell membrane potential, or voltage difference.

7 The combination of a chemical and electrical gradient can result in an electrochemical gradient that drives the movement of ions and molecules across a membrane.

8 an electrochemical membrane can have opposing components gradient.
