Receptor-mediated endocytosis:
1. Is a passive process
2. Involves only membrane transport proteins
3. Brings about the selective uptake of materials by enclosing them in membranous vesicles
4. Does not require energy
5. Is most likely to be found in cells that release large amounts of hormones
Exocytosis is a process by which cells
1. Pass substances out of the cell in vesicle
2. Pass substances out of the cell through the membrane by osmosis
3. release substances directly into the extracellular fluid through a pore
4. Release substances directly into the extracellular fluid through a pit
5. Identify substances in the environment
A cell engaged in phagocytosis must be
1. Engulfing a live organism
2. Acquiring a liquid
3. Engulfing a dead organism
4. Transporting bulk dissolved nutrients
5. Transporting bulk solid material
Coated pits are required for which type of membrane transport?
1. Receptor-mediated endocytosis
2. Phagocytosis
3. Pinocytosis
4. Exocytosis
Certain white blood cells are designed to engulf and destroy microbes such as bacteria. The process used to achieve this would be:
1. Phagocytosis
2. Receptor-mediated endocytosis
3. Pinocytosis
4. Exocytosis
