Q1: Endocytosis & Exocytosis

Question 1

What cell organelle helps to transport large molecules into or out of the cell?

Answer 1

Vacuole (Transport Vesicles)

Question 2

Which is an example of endocytosis?
a. White blood cells engulfing a virus and eliminating it.
b. Releasing a neurotransmitter for cellular communication.

Answer 2

A. White blood cells engulfing a virus and eliminating it.

Question 3

Is the process by which cells take in substances from outside of the cell by engulfing them in a vesicle.

Answer 3

Endocytosis

Question 4

It occurs when a portion of the cell membrane folds in on itself, encircling extracellular fluid and various molecules or microorganisms.

Answer 4

Endocytosis

Question 5

Functions in taking in nutrients for cellular growth, function, and repair.

Answer 5

Endocytosis

Question 6

Aids in capturing pathogens or other unknown substances that may endanger the organism.

Answer 6

Endocytosis

Question 7

disposing of old or damaged cells

Answer 7

Endocytosis

Question 8

Types of Endocytosis

Answer 8

Phagocytosis
Pinocytosis
Receptor-Mediated Endocytosis

Question 9

In phagocytosis, a cell engulfs a particle by extending ____________ around it and packaging it within a membranous sac call a food vesicle.

Answer 9

Pseudopodia

Question 10

A type of endocytosis in which the cell engulfs food and solid particles.

Answer 10

Phagocytosis

Question 11

A type of endocytosis in which the cell continually ‘gulps’ droplets of extracurricular fluid (liquid) into tiny vesicles, formed by the infoldings of the plasma membrane

Answer 11

Pinocytosis

Question 12

Is a specialized type of Pinocytosis that enables cell to acquire bulk quantities of specific substances, even though those substances may not be very concentrated in the extracellular fluid.

Answer 12

Receptor-Mediated Endocytosis

Question 13

A type of endocytosis by which the cell takes in active receptors

Answer 13

Receptor-Mediated Endocytosis

Question 13

Difference between:
Phagocytosis
Pinocytosis
Receptor-Mediated Endocytosis

Answer 13

Phagocytosis; Food particles and solid materials
Pinocytosis; fluid/liquid substances
Receptor-Mediated; Active Receptors

Question 14

is the process by which cells move materials from within the cell into the extracellular fluid.

Answer 14

Exocytosis

Question 15

It occurs when a vesicle fuses with the plasma membrane, allowing its contents to be released outside the cell.

Answer 15

Exocytosis

Question 16

Functions in removing toxins or waste products from the cell’s interior

Answer 16

Exocytosis

Question 17

Helps in facilitating cellular communication

Answer 17

Exocytosis

Question 18

facilitating cellular membrane growth, repair, signaling and migration

Answer 18

Exocytosis

Question 19

extracellular signals are not required. The majority of molecules traveling to the plasma membrane do so using this pathway.

Answer 19

Constitutive Secretion
