Final answer:
The statement "The Adaptins that bind to cargo receptors in the plasma membrane are different from those that bind to cargo in the Golgi apparatus." is true becausethe adaptins that interact with plasma membrane receptors are different from those at the Golgi apparatus.
Step-by-step explanation:
True, the adaptins that bind to cargo receptors in the plasma membrane are different from those that bind to cargo in the Golgi apparatus. This distinction is necessary due to the unique functions and destinations of the cargo involved. The plasma membrane is involved in processes such as receptor-mediated endocytosis, where specific substances are internalized by the cell. In contrast, the Golgi apparatus is integral in modifying, packaging, and sorting proteins and lipids for delivery to various destinations within or outside the cell, necessitating different adaptins for vesicle formation.
At the Golgi apparatus, specific cargo proteins are sorted into separate vesicles for different cellular or extracellular destinations. These vesicles are coated with coat proteins like clathrin and COP to promote vesicle budding. As the cargo proteins have different sorting signals, the adaptins involved must recognize these signals to ensure the correct packaging and delivery of the cargo. Therefore, the adaptins at the Golgi apparatus are geared towards recognizing sorting signals that direct vesicles to their appropriate destinations, which differs from the plasma membrane processes.
