Question

Which one of the following enzymes comprises a major part of enzyme-linked receptors:

• A. Receptor Histidine Kinase
• B. Receptor Threonine Phosphatase
• C. Receptor Serine Phosphatase
• D. Receptor Tyrosine Kinase

Hint:

Receptor Tyrosine Kinases (RTKs) play a key role in cellular communication and are essential for many important signaling pathways, particularly in regulating cell growth and metabolism.

Answer 1

The Correct Option is D

Receptor Tyrosine Kinase is a major component of enzyme-linked receptors. These receptors are involved in the activation of signaling pathways through the phosphorylation of tyrosine residues on specific proteins, leading to cellular responses like growth and differentiation.
