Question 24

The movement of substances through a membrane only by using the cell’s energy

Answer 24

Active transport

Question 25

Passive transport is the movement of substances from areas of _____ concentration to areas of ______ concentration

Answer 25

Higher to lower

Question 26

Active transport is the movement of substances from areas of _____ concentration to areas of ______ concentration

Answer 26

Lower to higher

Question 27

Define gradient

Answer 27

An increase or decrease in the magnitude of a property (e.g. temperature, pressure, or concentration) observed in passing from one point or moment to another.

Question 28

WHY does active transport require energy?

Answer 28

Active transport requires energy because it goes against the flow of gradient concentration.
