Passive and active transport

Question 1

Does Passive Transport require ATP?

Answer 1

No

Question 2

How do substances move in passive transport?

Answer 2

High to low concentration

Question 3

What influences substances in passive transport?

Answer 3

Temperature
Concentration
Distance

Question 4

What are the three types of passive transport

Answer 4

-simple diffusion
-faciliated diffusion
-osmosis

Question 5

In simple diffusion, in the cell, which substances diffuse directly though the bilayer?

Answer 5

only non-polar and lipid soluble substances

Question 6

What occurs during facilitated transport?

Answer 6

Molecules that can’t pass through the lipid bilayer because of size or polarity pass through using protein carriers or channels

Question 7

What is osmosis?

Answer 7

The diffusion of water cross a semi-permeable membrane

Question 8

Water moves depending on its _____through channels lined with proteins called______

Answer 8

concentration
aquaporins

Question 9

Does Active transport require Energy(ATP)?

Answer 9

Yes

Question 10

How do substances moves in active transport?

Answer 10

Low to high concentration

Question 11

Active transport requires membrane proteins that are specific for a particular substance. There are two types:

Answer 11

-Primary active transport
-Secondary active transport

Question 12

Primary active transport uses ATP directly move to solute across the

Answer 12

plasma membrane, against the gradient
Ex. Sodium-potassium pump

Question 13

Secondary active transport uses how many ATPS to indirecty move more than one substance across the cell membrane?

Answer 13

• A single

Question 14

ATP creates a gradient for one substance and as it flows back with the gradient it carriers another

Answer 14

substance with it
