Question

The endomembrane system when homogenized 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 _________.

Answer 1

The vesicles from the endomembrane system that function after homogenization and purification are called microsomes. They are involved in cellular processes like protein and lipid transport and modification.

Step-by-step explanation:

The collective term for the vesicles that retain their biological activity after homogenization and purification of the endomembrane system is microsomes.

The endomembrane system is a complex grouping of intertwined membranous compartments tasked with the synthesis, modification, and transport of proteins and lipids. It is pivotal in maintaining cellular function and comprises organelles such as the endoplasmic reticulum (ER), Golgi apparatus, lysosomes, and the plasma membrane.

When this system is homogenized, it forms vesicles known as microsomes. These microsomes, despite their varied origins within the original endomembrane structure, are often similar in size and can perform specialized tasks when isolated. Post-purification, microsomes frequently preserve their capacity to catalyze enzymatic reactions and serve in studies involving biochemical processes within cells.
