Question
Chapter 3, Problem 16SA
Summary Introduction
To answer:
Contrast the active processes: group translocation, endocytosis, active transport, and exocytosis.
Introduction:
The passive process and active process denote the movement from the outer layer of cytoplasmic membrane to the inner layer. In the active process, the energy is used for the movement of ions, proteins, and minerals. In some active process, the energy is utilized in the form of ATP.

Endocytosis and exocytosis are both forms of [ ACTIVE / PASSIVE ] transport that [ DO / DO NOT ] require
energy.
Outline an example/scenario in which a cell would need to perform a form of endocytosis.

b) Exocytosis is considered the opposite/reverse process as?
Pls help
Some nutrients and other types of particles can be taken into a cell when the cell's
plasma membrane encloses the particles and pinches off, forming a free-floating
vesicle inside the cell. A lysosome containing digestive enzymes then fuses with the
vesicle. Which term best classifies the uptake of such particles by the cell?
Simple diffusion
OEndocytosis
O Exocytosis
