Vesicles forming at the plasma membrane, or at the trans face of the Golgi, and destined only to fuse with endosomes and lysosomes, are generally not associated with which of the following proteins? dynamin proteins cargo receptor proteins clathrin proteins collagen proteins adaptin proteins
Structure and Composition of Cell Membrane
Despite differences in structure and function, all living cells in multicellular organisms are surrounded by a cell membrane. Just like the outer layer of the skin separates the body from its environment similarly, the cell membrane, also known as 'plasma membrane,' separates the inner content from its exterior environment.
Cell Membrane
The cell membrane is known by different names like plasma membrane or cytoplasmic membrane, or biological membrane. The term "cell membrane" was first introduced by C. Nageli and C. Cramer in the year 1855. Later on, in 1931, the term "plasmalemma" for cell membrane was given by J. Plowe. The cell membrane separates the cell's internal environment from the extracellular space. This separation allows the protection of cells from their environment.
Prokaryotes vs Eukaryotes
The cell is defined as the basic structural and functional unit of life. The cell membrane bounds it. It is capable of independent existence.
Vesicles forming at the plasma membrane, or at the trans face of the Golgi, and destined only to fuse with endosomes and lysosomes, are generally not associated with which of the following proteins?
- dynamin proteins
- cargo receptor proteins
- clathrin proteins
- collagen proteins
- adaptin proteins
The vesicles help in the transportation of cargo proteins to a distinct location in the cell. They are an important component of the secretory and endocytic pathway. These vesicles are coated with three different types of proteins: COPI, COPII, or clathrin. The reversible polymerization of these proteins aid in the formation of three different types of coated vesicles.
