GENBIO L1- TRANSPORT

Question 1

Some small molecules, such as carvon dioxide move across the crll membrane via?

Answer 1

Diffusion

Question 2

Particles move from an area of HIGH CONCENTRATION to LOW CONCENTRATION

Answer 2

Diffusion

Question 3

Molecules move down their gradients through the membrane

Answer 3

Simple Diffusion

Question 4

Diffusion that is helped by a membrane transport channel/carriers

Answer 4

Facilitated Diffusion

Question 5

Movement of solvent particles in a semi-permiable membrane into a region of higher solute concentration

Answer 5

Osmosis

Question 6

Causes the cell to be flavid (shrinkled/wrinkled) due to loss of water in extreme cases the cell will be plasmolyzed or die by dehydration

Answer 6

Hypertonic Solution

Question 7

“The same” meaning there is no change and there is a same distribution of cells

Answer 7

Isotonic Solution

Question 8

The cell will gain water causing it to die evetually

Answer 8

Hypotonic Solution

Question 9

Transport that directly ises ATP for energy

Answer 9

Active Transport

Question 10

Example of a Primary Active Transport:

Answer 10

Sodium-Potassium pump

Question 11

The rapid rise in Potential, initiated by the opening of Sodium ion channels

Answer 11

Depolarization

Question 12

The subsequent return to resting potential, mediated by the openifn of potassium ion channels

Answer 12

Repolarization

Question 13

Secondary Active Transport examples:

Answer 13

Uniport
Antiport
Symport

Question 14

When a particular tyoe of molecules moves across a membrane through a carrier protein, independent of other molecules

Answer 14

Uniport

Question 15

A mechanism for the coupled transportation of two different molecules or Ions passing trough a membrane in opposite direction

Answer 15

Antiport

Question 16

A type of transport because the molecules will travel together in the same direction in relation to eachother

Answer 16

Symport

Question 17

Cell eating is a process by which cell take in large or solid particles through ingolding of the cell membranr to form endocytosis.

Answer 17

Phagocytosis

Question 18

Cell drinking is a process of taking in fluids into the cell by invagination of the cell membrane.

Answer 18

Pinocytosis

Question 19

The plasma membrane becomes indented and forms a pit. The pit then closes and pinches off to forma vesicles, which eventually carries the molecules inside the cytoplasm.

Answer 19

Receptor-Mediated Endocytosis

Question 20

Materials for export, it is the opposite of endocytosis.

Answer 20

Exocytosis
