When homogenized, the endomembrane system is broken up into vesicles, which are heterogeneous but similar in size. These vesicles can be purified and, after purification, often retain their biological activity. They are collectively referred to as _________.
A)endosomes
B)microsomes
C)ribosomes
D)minisomes
E)lysosomes

Question

Quizplus · Accepted Answer

The vesicles that result from homogenization and purification of the endomembrane system are called microsomes. They are heterogeneous in their composition but are similar in size. Microsomes can retain their biological activity, which makes them useful for studying the functions of various membrane-bound proteins, enzymes, and other components of the endomembrane system. Endosomes are vesicles involved in sorting and transporting materials within cells. Ribosomes are organelles involved in protein synthesis, and lysosomes are organelles involved in degradation and recycling of cellular components. "Minisomes" is not a term used in biology.
