Отличие биологической мембраны от цитоплазматической Не копируйте с вики Я знаю,что такое клеточная мембрана Мне нужно отличие друг от друга

Answer 1

Термин "биологические мембраны" объединяет цитоплазматическую (клеточную) мембрану, мембраны органоидов (ЭПР, ядра, КГ, пластид, лизосом, митохондрий). 
И действительно, все эти биологические мембраны отличаются своим составом (преобладанием тех или иных белков, гликопротеинов, углеводов, расположением фосфолипидов и т.д.), толщиной, строением и т.д.
Например,мембраны лизосом содержит специальные белки, которые специализированы на закачку внутрь лизосом протонов водрода. Мембрана ядра содержит поры, через которые проходят, синтезированные в ядрышке, рибосомы.
Мембрана эритроцита содержит много белков (спектрин, анкирин, гликофорин, полоса 3) и мощный слой гликокаликса (углеводов), который обеспечивает эритроциту отрицательный заряд на поверхности.

Difference between Biological Membrane and Cytoplasmic Membrane

The biological membrane, also known as the cell membrane or plasma membrane, and the cytoplasmic membrane are two distinct components of a cell. While they are both involved in cellular processes, there are some key differences between them.

Biological Membrane: - The biological membrane is a selectively permeable barrier that surrounds the cell and separates its internal environment from the external environment. - It is composed of a phospholipid bilayer with embedded proteins and other molecules. - The main function of the biological membrane is to regulate the movement of substances into and out of the cell, allowing for the maintenance of homeostasis. - It plays a crucial role in cell signaling, cell adhesion, and cell recognition. - The biological membrane is found in all types of cells, including prokaryotic and eukaryotic cells.

Cytoplasmic Membrane: - The cytoplasmic membrane, also known as the inner membrane or plasma membrane, is a specific type of biological membrane found in prokaryotic cells. - It is located just beneath the cell wall and surrounds the cytoplasm. - The cytoplasmic membrane is composed of a phospholipid bilayer with embedded proteins and other molecules, similar to the biological membrane. - Its main function is to regulate the transport of molecules into and out of the cell, as well as to maintain the integrity and shape of the cell. - In prokaryotic cells, the cytoplasmic membrane is responsible for various cellular processes, including nutrient uptake, waste removal, and energy production.

In summary, the main difference between the biological membrane and the cytoplasmic membrane lies in their location and the types of cells in which they are found. The biological membrane is present in all types of cells, while the cytoplasmic membrane is specific to prokaryotic cells. Both membranes are involved in regulating the movement of substances into and out of the cell, but the cytoplasmic membrane is particularly important for the functioning of prokaryotic cells.
