To regulate large protein complexes there is a single, powerful regulator of the entire complex.
A
True
B
False
Verified step by step guidance1
Understand the concept of protein complexes: Protein complexes are groups of two or more associated polypeptide chains. They often work together to perform a specific function within the cell.
Learn about regulation of protein complexes: Regulation can occur at multiple levels, including transcriptional, translational, and post-translational modifications. It often involves multiple regulators rather than a single one.
Consider examples of regulation: For instance, the proteasome, a large protein complex responsible for degrading unneeded or damaged proteins, is regulated by multiple factors including ubiquitin tags and regulatory particles.
Evaluate the statement: The statement suggests that there is a single regulator for large protein complexes. However, in biological systems, regulation is typically complex and involves multiple factors.
Conclude based on biological principles: Given the complexity and the need for precise control in cellular processes, it is unlikely that a single regulator would control an entire large protein complex. Therefore, the statement is false.
