Final answer:
Receptor-mediated endocytosis, exocytosis, and changes in the membrane organization involve a change in position of the cell or a cell structure. These processes are examples of active transport, which requires energy to move substances across the cell membrane.
Step-by-step explanation:
Receptor-mediated endocytosis, exocytosis, and changes in the membrane organization involve a change in position of the cell or a cell structure. These processes are examples of active transport, which requires energy to move substances across the cell membrane. Receptor-mediated endocytosis is the process by which cells take in specific molecules or particles by forming vesicles. Exocytosis, on the other hand, is the process by which cells release substances outside of the cell through the fusion of vesicles with the cell membrane.
