Cell Transport Quiz

What is the primary function of endocytosis in cell transport?

• To synthesize proteins within the cell

• To transport oxygen across the cell membrane

• To bring substances into the cell

• To expel waste materials from the cell

Which type of endocytosis is responsible for engulfing large particles like food?

• Pinocytosis

• Receptor-mediated endocytosis

• Phagocytosis

• Exocytosis

What is formed when the cell membrane wraps around a particle during endocytosis?

• A mitochondrion

• A lysosome

• A ribosome

• A vesicle

How does receptor-mediated endocytosis differ from other types of endocytosis?

• It does not involve the cell membrane

• It is used for expelling waste

• It uses specific protein receptors to identify particles

• It involves the engulfing of liquids

What is the main role of exocytosis in nerve cells?

• To store energy

• To replicate DNA

• To absorb nutrients

• To release neurotransmitters

Which process involves the fusion of vesicles with the cell membrane to release contents outside the cell?

• Phagocytosis

• Endocytosis

• Pinocytosis

• Exocytosis

What is a common feature of both endocytosis and exocytosis?

• They both involve the transport of small ions

• They both require energy in the form of ATP

• They both occur only in plant cells

• They both deal with large particles

What does the prefix 'endo-' signify in the context of cell transport?

• Synthesizing proteins

• Exiting the cell

• Entering the cell

• Breaking down substances

Which process is primarily responsible for removing waste materials from the cell?

• Receptor-mediated endocytosis

• Endocytosis

• Exocytosis

• Pinocytosis

What is the significance of the prefix 'exo-' in exocytosis?

• It indicates the process of entering the cell

• It signifies the process of exiting the cell

• It refers to the synthesis of proteins

• It denotes the breakdown of molecules
