Cells actively involved in secreting proteins would contain large numbers or quantities of
A)lysosomes.
B)peroxisomes.
C)rough endoplasmic reticulum.
D)smooth endoplasmic reticulum.

Question

Quizplus · Accepted Answer

Rough endoplasmic reticulum (RER) is responsible for protein synthesis and secretion. Therefore, cells involved in secreting proteins would have a large quantity of RER. The RER has ribosomes attached to its surface, giving it a "rough" appearance. These ribosomes are responsible for protein synthesis, allowing for the production of secreted proteins. Lysosomes are responsible for the breakdown and recycling of cellular waste, while peroxisomes are responsible for metabolizing fatty acids and detoxifying harmful substances. Smooth endoplasmic reticulum (SER) is involved in lipid synthesis and detoxification but not in protein secretion.
