Transport mechanism

Question 1

A cell structure that regulates what kind of substances leave and enter the cell.

Answer 1

The Cell Membrane

Question 2

It is semi-permeable thus protecting the cell by controlling what enters and comes out of it.

Answer 2

Structure of the Cell Membrane

Question 3

Major components:

Answer 3

Phospholipid bilayer

Carbohydrates

Proteins

Question 4

some pass by diffusion or osmosis

Answer 4

Membrane mostly permeable.

Question 5

requires transport proteins

Answer 5

Membrane mostly impermeable

Question 6

requires transport proteins

Answer 6

Membrane completely impermeable

Question 7

A collection of transport mechanisms that helps in the movements of particles across or through a membranous barrier.

Answer 7

Membrane Transport

Question 8

There are two major ways in which molecule or particles can move across a membrane

Answer 8

Passive transport / Active transport

Question 9

This process does not require energy (ATP): for molecules to pass through cell membrane. The materials are transported from higher concentration to lower concentration

Answer 9

Passive transport

Question 10

This process requires energy (ATP) for molecules to pass through cell membrane. The materials are transported from lower concentration to higher concentration.

Answer 10

Active transport

Question 11

It allows molecules to pass directly through the membrane from a region of high concentration to low concentration.

Answer 11

Simple Diffusion

Question 12

It involves the movement of water molecules through semipermeable membrane from high water concentration to low water concentration.

Answer 12

Osmosis

Question 13

Types of Solution

Answer 13

HYPERTONIC
ISOTONIC
HYPOTONIC

Question 14

solution is one that has a higher solute concentration inside the cell than outside.

Answer 14

Hypotonic

Question 15

solution is one that has a higher solute concentration outside the cell than inside.

Answer 15

Hypertonic

Question 16

solution is one that has the same concentration of solutes both inside and outside the cell.

Answer 16

Isotonic

Question 17

It is the movement of molecules from an area of high concentration to low concentration with the aid of transport channel or carrier protein to pass through.

Answer 17

Facilitated Diffusion

Question 18

A type of active transport that directly uses energy in the form of ATP to power the movement of molecules across membrane.

Answer 18

Primary Active Transport

Question 19

A method of transport in which the electrochemical potential difference created by pumping ions out of the cell is used to transport molecules across a membrane.

Answer 19

Secondary Active Transport

Question 20

The cell membrane takes in particles by engulfing them in a vesicle.

Answer 20

Endocytosis

Question 21

The cell fuses with the plasma membrane releasing its content out of the cell.

Answer 21

Exocytosis

Question 22

(cell drinking)

Answer 22

Pinocytosis

Question 23

(cell eating)

Answer 23

Phagocytosis
