Which of the following describes molecular mimicry in cell signaling?
A
A method of signal amplification through secondary messengers
B
A type of signaling where hormones are released into the bloodstream
C
A mechanism where cells communicate through direct contact
D
A process where a molecule mimics the structure of another to interfere with signaling pathways
Verified step by step guidance1
Understand the concept of molecular mimicry: Molecular mimicry involves a molecule resembling another molecule's structure, allowing it to interfere with or alter signaling pathways.
Identify the role of molecular mimicry in cell signaling: It can disrupt normal signaling by binding to receptors or enzymes, preventing the actual signaling molecule from binding.
Consider examples of molecular mimicry: Some pathogens use molecular mimicry to evade immune responses by mimicking host molecules.
Differentiate molecular mimicry from other signaling processes: Unlike signal amplification or direct contact signaling, molecular mimicry involves structural imitation to alter signaling.
Recognize the impact of molecular mimicry: It can lead to altered cellular responses, potentially affecting processes like immune response or hormone regulation.
