Question

Which of the following best describes a way in which cellular response might be affected if scaffolding proteins were not present in a cell's signal transduction pathway?

Cell signaling specificity would be absent, resulting in similar responses from multiple signals.
Inactivation mechanisms would be inhibited, causing an inability to terminate the signal.
Phosphorylation cascades would not be activated, decreasing signal transduction efficiency.
Signaling molecules would not bind to receptor proteins, preventing G protein activation.

Answer 1

c. Phosphorylation cascades would not be activated, decreasing signal transduction efficiency.
