Question
Chapter 5, Problem 6FTB
Summary Introduction
To review:
The given blank space in the statement, “the general process by which fluids or particles are transported out of cells is called ______. Does this process require energy? ______. The substances to be expelled are transported within the cell in membrane enclosed sacs called _______.
Introduction:
Most of the cellular activities that occur within the body are energy-demanding processes. Transports of molecules are among one of them. Some processes like active transport, endocytosis and exocytosis are important for maintenance of concentration gradients, acquiring food and also expelling wastes and also for communication with other cells.

In this process, the membrane of the secretory vesicle becomes part of the cell membrane because small pieces of the membrane are continually added to the cell membrane, one would expect the cell membrane to become larger and larger as secretion continues. The cell membrane stays the same size, however. Explain how this happens.arrow_forward
