What is formed during the process of endocytosis?

• A cell wall

• A vesicle

• A nucleus

• A mitochondrion

What is the primary function of marker molecules in membrane proteins?

• Allow cells to identify other cells or molecules

• Anchor cells to other cells

• Form passageways through the plasma membrane

• Move ions across the membrane

Which type of membrane protein anchors cells to other cells or extracellular molecules?

• Marker molecules

• Attachment proteins

Which type of endocytosis is known as "cell drinking"?

• Phagocytosis

• Pinocytosis

• Exocytosis

• Diffusion

Which process is referred to as "cell eating"?

• Pinocytosis

• Exocytosis

• Phagocytosis

• Receptor-mediated endocytosis

What distinguishes receptor-mediated endocytosis from other types?

• It uses energy

• It involves specific receptors

• It occurs in all cells

• It releases substances

What is exocytosis?

• The process of vesicle contents being expelled from a cell

• The process of vesicle contents being absorbed into a cell

• The process of vesicle contents being stored within a cell

• The process of vesicle contents being transformed within a cell

What role do secretory vesicles play in exocytosis?

• They store and transport substances to be expelled from the cell

• They absorb substances into the cell

• They break down substances within the cell

• They convert substances into energy

Which of the following processes is similar to exocytosis but involves intake rather than expulsion?

• Endocytosis

• Photosynthesis

• Respiration

• Fermentation
