Cellular Transport

Question 1

Two types of cellular transport:

Answer 1

Passive and Active Transport

Question 2

A diffusion of a substance across a membrane with “No energy investment”.

Answer 2

Passive Transport

Question 3

CO2, H2O and O2 easily diffuse across plasma membranes.

Answer 3

Passive Transport

Question 4

Move from HIGH TO LOW concentration (concentration gradient)

Answer 4

Passive Transport

Question 5

Can be Diffusion, Facilitated Diffusion, Osmosis

Answer 5

Passive Transport

Question 6

Is the tendency for molecules of any substance to “ Spread out evenly” into available space.

Answer 6

Diffusion

Question 7

Is a type of passive Transport aided by “transport proteins”.

Answer 7

Facilitated Diffusion

Question 8

Is the movement of water across a semipermeable membrane (diffusion of water).

Answer 8

Osmosis

Question 9

Transport proteins speed the movement of molecules across the plasma membrane

Answer 9

Facilitated Diffusion

Question 10

Is affected by the concentration gradient of dissolved substances called the solutions tonicity.

Answer 10

Osmosis

Question 11

Kinds of osmosis:

Answer 11

Hypotonic solution
Isotonic solution
Hypertonic solution

Question 12

The concentration of solutes outside the cell is LOWER than the inside the cell.

Answer 12

Hypotonic solution

Question 13

Water comes inside the cell.

Answer 13

Hypotonic solution

Question 14

Clue: Turgid pressure

Answer 14

Hypotonic solution

Question 15

The pressure exerting on the plasma membrane against the cell wall. ( Swell, Burst, Lysed)

Answer 15

Turgid pressure

Question 16

The concentration of solutes outside the cell is the same as it is inside the cell.

Answer 16

Isotonic solution

Question 17

There will be NO NET MOVEMENT OF WATER.

Answer 17

Isotonic solution

Question 18

The concentration of solutes outside the cell is GREATER than the inside of the cell.

Answer 18

Hypertonic solution

Question 19

Water goes outside the cell.

Answer 19

Hypertonic solution

Question 20

Clues: Plasmolysis, Shrink, Shivel, Dehydrated

Answer 20

Hypertonic solution

Question 21

Uses energy to move solutes against their concentration gradient.

Answer 21

Active Transport

Question 22

Requires Energy, usually ATP.

Answer 22

Active Transport

Question 23

Example: Ion pumps, contransport, bulk transport (exocytosis, endocytosis)

Answer 23

Active Transport

Question 24

Answer 24

Chromosome ➡️ DNA➡️Gene➡️Codon➡️ Nucleotide (smallest of all)
