Why are there motor proteins associated with both actin filaments and microtubules but not intermediate filaments? - ANSWER Actin filaments and microtubules are highly polarized, therefore allowing motor proteins to form associations with them. Intermediate filaments are unpolarized and do not bind nucleotides such as ATP, leading to lack of motor protein associations (which are ATP driven). How does the hydrolysis of ATP cause myosin to move along the actin filament? - ANSWER ATP hydrolysis ...

A 25-year-old man comes to the physician because of persistent, high-pitched ringing noises in his ears. He has also been losing his balance lately. A CT scan of the head shows bilateral tumors involving the vestibulocochlear nerve. Which of the following chromosomes contains the tumor suppressor gene most likely to be involved in this case? 3p 5q 13q 17q 22q - E)22q The patient has bilateral acoustic neuromas, probably due to neurofibromatosis type 2, an autosomal dominant inheri...

This study guide provides a comprehensive overview of key cell signaling pathways, including GPCR, Receptor Tyrosine Kinase (RTK), Wnt, and Notch cascades. It covers the molecular mechanisms involved in each pathway, highlighting important signaling molecules, protein interactions, and downstream effects. Additionally, the guide explores concepts such as transcription factor activation, proteolytic cleavage, and the role of beta-catenin and the proteasome in signal transduction.
