Cell Transport- ai

Question 1

What is the definition of cell transport?

Answer 1

Cell transport refers to the movement of materials across the cell membrane.

Question 2

What are the two main types of cell transport?

Answer 2

The two main types of cell transport are passive transport and active transport.

Question 3

True or False: Passive transport does not require energy input from the cell.

Answer 3

True

Question 4

Which type of cell transport involves the movement of molecules from an area of higher concentration to an area of lower concentration?

Answer 4

Passive transport

Question 5

What is diffusion?

Answer 5

Diffusion is the passive movement of molecules from an area of higher concentration to an area of lower concentration.

Question 6

What is osmosis?

Answer 6

Osmosis is the diffusion of water molecules across a selectively permeable membrane.

Question 7

Which type of cell transport requires energy in the form of ATP?

Answer 7

Active transport

Question 8

What is endocytosis?

Answer 8

Endocytosis is the process by which cells take in large molecules by engulfing them in a vesicle.

Question 9

What is exocytosis?

Answer 9

Exocytosis is the process by which cells release large molecules by fusing vesicles with the cell membrane.

Question 10

What is facilitated diffusion?

Answer 10

Facilitated diffusion is the passive movement of molecules across the cell membrane with the help of transport proteins.

Question 11

Which type of cell transport involves the use of transport proteins to move molecules across the membrane?

Answer 11

Facilitated diffusion

Question 12

What is the difference between simple diffusion and facilitated diffusion?

Answer 12

Simple diffusion does not require transport proteins, while facilitated diffusion does.

Question 13

Which type of cell transport is responsible for the movement of ions against their concentration gradient?

Answer 13

Active transport

Question 14

What is the sodium-potassium pump an example of?

Answer 14

The sodium-potassium pump is an example of active transport.

Question 15

Which type of cell transport maintains the cell’s internal environment by controlling what enters and exits the cell?

Answer 15

Cell transport

Question 16

What is the role of the cell membrane in cell transport?

Answer 16

The cell membrane acts as a selectively permeable barrier that regulates the movement of materials in and out of the cell.

Question 17

What is the main function of cell transport?

Answer 17

The main function of cell transport is to maintain homeostasis by regulating the internal environment of the cell.

Question 18

Which type of cell transport requires energy input from the cell?

Answer 18

Active transport

Question 19

What is the driving force for passive transport processes?

Answer 19

The driving force for passive transport processes is the concentration gradient.

Question 20

What is the role of the sodium-potassium pump in cell transport?

Answer 20

The sodium-potassium pump helps maintain the cell’s resting membrane potential and plays a crucial role in nerve conduction.

Question 21

Which type of cell transport involves the movement of molecules across the membrane using transport proteins?

Answer 21

Facilitated diffusion

Question 22

What is the role of aquaporins in cell transport?

Answer 22

Aquaporins are specialized water channels that facilitate the movement of water molecules across the cell membrane.

Question 23

Which type of cell transport is responsible for the movement of water across the cell membrane?

Answer 23

Osmosis

Question 24

What is the difference between active transport and passive transport?

Answer 24

Active transport requires energy input, while passive transport does not.

Question 25

What is the role of vesicles in cell transport?

Answer 25

Vesicles are membrane-bound organelles that play a key role in endocytosis and exocytosis.

Question 26

Which type of cell transport involves the fusion of vesicles with the cell membrane to release molecules outside the cell?

Answer 26

Exocytosis

Question 27

What is the purpose of endocytosis in cell transport?

Answer 27

Endocytosis allows the cell to take in large molecules, nutrients, and other substances from the external environment.

Question 28

Which type of cell transport is responsible for the movement of large molecules into the cell?

Answer 28

Endocytosis

Question 29

What is the primary function of the sodium-potassium pump in cell transport?

Answer 29

The primary function of the sodium-potassium pump is to maintain the cell’s resting membrane potential and regulate ion concentrations.

Question 30

Which type of cell transport requires the cell to expend energy in the form of ATP?

Answer 30

Active transport

Question 31

What is the significance of cell transport in cellular function?

Answer 31

Cell transport is essential for the survival and proper functioning of cells by ensuring the balance of nutrients and waste products.

Question 32

Which type of cell transport is involved in the movement of substances from an area of lower concentration to an area of higher concentration?

Answer 32

Active transport

Question 33

What is the importance of maintaining homeostasis in cell transport?

Answer 33

Maintaining homeostasis through cell transport ensures that the internal environment of the cell remains stable and functional.
