Capitolo 3, Problema 20
In their anatomy lab, many students are exposed to the chemical preservatives phenol, formaldehyde, and alcohol. Our cells break down these toxins very effectively. What cellular organelle is responsible for this?
Guida verificata passo dopo passo1
Identify the function of cellular organelles involved in detoxification processes within the cell.
Recall that the organelle responsible for breaking down toxins and harmful substances like phenol, formaldehyde, and alcohol is the smooth endoplasmic reticulum (SER).
Understand that the smooth endoplasmic reticulum contains enzymes that metabolize and detoxify chemicals, making them less harmful to the cell.
Recognize that other organelles, such as lysosomes, are involved in digestion of cellular waste, but detoxification of chemicals primarily occurs in the smooth endoplasmic reticulum.
Summarize that the smooth endoplasmic reticulum plays a key role in metabolizing and detoxifying chemical preservatives encountered in the anatomy lab.
