Which processes are involved in the recycling of cell membrane ? What is the use of recycling ?

Explanation

**Step-by-Step Solution:**

1. **Understanding Cell Membrane Recycling**: The recycling of the cell membrane involves processes that allow the cell to manage its membrane components effectively. The two primary processes involved are endocytosis and exocytosis.

2. **Endocytosis**: This is the process where the cell engulfs external substances, including nutrients and foreign molecules, by folding its membrane inward. This forms vesicles that bring these substances into the cell.

3. **Exocytosis**: In contrast, exocytosis is the process where substances inside the cell are packaged into vesicles and expelled out of the cell. This is crucial for removing waste materials and secreting substances like hormones and neurotransmitters.
