The Difference Between Pinocytosis and Receptor-Mediated Endocytosis Is That

question 30

Multiple Choice

The difference between pinocytosis and receptor-mediated endocytosis is that

• A)pinocytosis brings only water into the cell, but receptor-mediated endocytosis brings in other molecules as well.
• B)pinocytosis increases the surface area of the plasma membrane whereas receptor-mediated endocytosis decreases the plasma membrane surface area.
• C)pinocytosis is nonselective in the molecules it brings into the cell, whereas receptor-mediated endocytosis offers more selectivity.
• D)pinocytosis requires cellular energy, but receptor-mediated endocytosis does not.
• E)pinocytosis can concentrate substances from the extracellular fluid, but receptor-mediated endocytosis cannot.

Definitions:

Spinal Cord

The long, thin, tubular structure made up of nervous tissue, which extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column.

Neurons

The basic units of the nervous system; cells that receive, integrate, and transmit information in the nervous system. Neurons operate through electrical impulses, communicate with other neurons through chemical signals, and form neural networks.

Sensory Information

Data received by the sensory organs (like eyes, skin, ears) and transmitted to the brain for processing and interpretation.

Presynaptic Neurons

Neurons that transmit signals to a synapse, the junction between two nerve cells, to communicate with postsynaptic neurons.
