Cellular Transport

Question 0

The two types of cellular transport

Answer 0

Passive transport and active transport

Question 1

What is the principal part of the cell that is involved on cell transportation?

Answer 1

The cell membrane

Question 2

Describe the passive transport

Answer 2

Requires no energy from the cell, always goes from an area of higher concentration from one of lower concentration, it’s divided by three types of passive transport

Question 3

What are the three types of passive transport?

Answer 3

Diffusion, osmosis and facilitated diffussion

Question 4

Describe the diffusion

Answer 4

The movement of a substance from an area of higher concentration to one of lower concentration.

Question 5

The osmosis is…

Answer 5

The diffusion of water through a semi-permeable membrane, like the cell membrane, it involves solute and water, it has tree types of solutions.

Question 6

What are hypertonic solutions?

Answer 6

Are those that has more solute than water

Question 7

What are isotonic solutions?

Answer 7

In those that water and solute are in the same concentrations.

Question 8

What are hypotonic solutions?

Answer 8

Solutions that has more water than solute.

Question 9

What happened when a cell has more water than solute?

Answer 9

Cells swell and burst

Question 10

What happened when a cell has more solute than water like salt?

Answer 10

The cell shrink and shrivel

Question 11

Diffrence between osmosis and diffusion

Answer 11

The osmosis is involved in water transportation and diffusion in elements transportation.

Question 12

What is facilitated diffusion?

Answer 12

Is the transportation of molecules and ions trough the cell membrane, it requires no energy from the cell

Question 13

What is active transport?

Answer 13

Is the transportation of molecules or ions trough a membrane, you need ATP for the process

Question 14

Types of active transport are…

Answer 14

Primary active transport, secondary active transport and endocytosis

Question 15

In what consist the primary active transport?

Answer 15

Consist in use the ATP to move molecules through the membrane, it expends energy to move sodium ions out and replace them with potassium ions to maintain positive charged the cell

Question 16

What is the secondary active transport?

Answer 16

Molecules are moved through a membrane as a result of the diffusion of another substance.

Question 17

What is endocytosis?

Answer 17

The import of materials to the cell by foldings of the cell membrane, there are three types of endocytosis.

Question 18

The three types of endocytosis are…

Answer 18

Phagocytosis, Pinocytosis and receptor mediated Endocytosis.

Question 19

What is the Phagocytosis?

Answer 19

Is the process when the cell engulf solid particles like food by the cell membrane to form a food vacuole

Question 20

What is pinocytosis?

Answer 20

Is the process when every substance found in the invagination area is brought to the cell

Question 21

What is the receptor mediated endocytosis?

Answer 21

Is a process when cells internalize molecules and viruses involves the vesicles.

Question 22

What is exocytosis?

Answer 22

Is the reverse of endocytosis, they produce secretion, the cell trow out proteins or secretive proteins to regulate the cell by vesicles
