Question

Amoeba engulfs a bacterial cell. Once the bacterial cell has been digested, Amoeba will dispose the indigestible materials by which of the following processes?

• A. Diffusion
• B. Through gated channels in membrane proteins
• C. Exocytosis
• D. Active transport

Answer 1

The correct option is C Exocytosis

Exocytosis is the process of expulsion of materials from the cell. Each vesicle which consists wastes from the cellular digestion in amoeba moves to the plasma membrane and fuses with it. In this fused membrane, a channel opens between the lumen of the vesicle and the exterior of the cell and the exportable material passes out.
