A cell in an early developing embryo has a damaging mutation in a transmembrane receptor for receiving short-range chemical signals. Which of the stages of signaling will be affected by this, either directly or indirectly?

Cell signaling involves detection (reception) and transduction, which elicits a cellular response. Which is not true of transduction? May involve many steps (pathway) or only one step. Each pathway can lead to only one response. May be propagated by proteins or secondary messengers. May amplify the signal. Begins when a receptor is activated by a messenger molecule and changes conformation.

A type of localized signaling in which a cell secretes a signal molecule that affects neighboring cells is best described as which of the following? hormonal signaling paracrine signaling autocrine signaling cell-cell contact-dependent signaling
Shadi I.
A mutated form of the a subunit of the heterotrimeric G protein has been identified; this form readily exchanges nucleotides even in the absence of an activated receptor. What would be the effect on a signaling pathway containing the mutated a subunit? The signaling pathway will remain activated. The signaling pathway will remain inactivated. The signaling pathway will not be affected.
