Which molecule can function as a recognition signal for interactions between animal cells?
A) RNA
B) Phospholipid
C) Cholesterol
D) Fatty acid
E) Glycoprotein

Question

Quizplus · Accepted Answer

Glycoproteins are proteins that have carbohydrates attached to them, and they often serve as recognition signals for interactions between animal cells. These carbohydrates can be involved in cell signaling and can play a role in cell adhesion, immune responses, and development. RNA, phospholipids, cholesterol, and fatty acids are all important molecules in the cell, but they do not typically serve as recognition signals for cell-cell interactions.
