Question

Eukaryotic cells are able to trigger the release of material from secretory vesicles to the extracellular space using a process called exocytosis. An example of materials commonly released this way is _____________.

1) hormones
2) nucleic acids
3) sugars
4) cytosolic proteins

Answer 1

Eukaryotic cells use exocytosis to release various materials into the extracellular space, with hormones being a common example. This process facilitates functions such as communication between cells and removal of waste products.

Step-by-step explanation:

Exocytosis and Secretory Vesicles

Exocytosis is a critical cellular process in which secretory vesicles transport and release their contents to the extracellular space. This process is vital for various cell functions such as the removal of waste, secretion of substances for intercellular communication, and the discharge of materials like extracellular matrix proteins. Additionally, certain cells have regulated secretory pathways, which release substances only upon specific triggers or signals.

One of the common examples of materials released via exocytosis is hormones. These are secreted by endocrine cells and play a pivotal role in regulating physiological functions throughout the body. Other examples include the release of digestive enzymes by stomach and pancreas cells, histamines by immune cells, and neurotransmitters by neurons at synaptic clefts.

To answer the student's question directly, among the options provided, the example of materials commonly released through exocytosis would be hormones. This reflects the process's significance in areas like metabolic regulation and response to environmental changes or threats, such as the presence of pathogens.
