Transport in cells

Question 1

What is osmosis?

Answer 1

Osmosis is the movement of water molecules from an area of high water potential to an area of lower water potential through a partially permeable membrane

Question 2

What is diffusion?

Answer 2

Diffusion is the movement of molecules from an area of high concentration to an area of low concentration down a concentration gradient

Question 3

What is facilitated diffusion?

Answer 3

The movement of large or charged molecules from an area of high to low concentration via protein channels, or by bind into complimentary transmembrane carrier proteins

Question 4

What is active transport?

Answer 4

The movement of molecules or ions from an area of low concentration to an area of high concentration up a concentration gradient

Question 5

What is endocytosis?

Answer 5

A type of bulk movement of material into cells

Question 6

what is exocytosis?

Answer 6

A type of book movement of material out of cells

Question 7

What is pinocytosis?

Answer 7

The ingestion of liquid by cells

Question 8

What is phagocytosis?

Answer 8

The ingestion of solid material by cells

Question 9

What type of energy do passive process is use?

Answer 9

Do you is kinetic energy from cells?

Question 10

Which transport processes a passive

Answer 10

-Diffusion
-Osmosis
-Facilitated diffusion

Question 11

Which transport processes are active?

Answer 11

• Active transport
• Endocytosis
• Exocytosis
• phagocytosis
• Pinocytosis

Question 12

what does it mean if a solution is hypertonic?

Answer 12

It means that solution is more concentrated on the inside of the cell, so it moves into the sell by osmosis

Question 13

what does it mean if a solution is hypertonic?

Answer 13

The solution is less concentrated inside the cell, so it moves out of the cell by osmosis

Question 14

What does it mean by isotonic?

Answer 14

The concentration of water is equal inside, and outside the cell switch reach dynamic equilibrium (there is no net movement)

Question 15

Describe exocytosis

Answer 15

• vesicles in the cell move towards the cell membrane
• Physical membrane fuses with the plasma membrane of the sale and releases its contents
• The contents travels through the plasma membrane and out of the cell

Question 16

Describe endocytosis

Answer 16

• The material binds to receptors on the cell membrane
• The cell membrane thoughts around the material
• It pinches of to form a vehicle inside the cell

Question 17

how do ions and polar molecules move into a sound?

Answer 17

they move via facilitated diffusion through protein channels

Question 18

How to larger molecules move into a cell

Answer 18

The movie a facility, diffusion by binding to a compliment to transmembrane carrier protein

Question 19

describe phagocytosis:

Answer 19

• chemotoxins and microbes are here to the phagocyte
• they are ingested into the cell body
• This forms of phagosome
• Lysosomes fuse to the phagosome to make a phagolysome
• The enzymes from the lysome digests of microbes
• The cell becomes a residual body containing the digestive material
• The waste is the discarded out of the cell
