Which of the following can function in signal transduction in plants?
I. calcium ions
II. nonrandom mutations
III. receptor proteins
IV. red light
V. second messengers

Question

Quizplus · Accepted Answer

I, III, and V (calcium ions, receptor proteins, and second messengers) are all known to play roles in signal transduction in plants. Calcium ions act as a secondary messenger in various signaling pathways. Receptor proteins on the cell surface or inside the cell can recognize and bind to specific signaling molecules. Second messengers, such as calcium ions or cyclic AMP, relay signals received at the cell surface to target molecules inside the cell. Nonrandom mutations and red light do not function in the same way; red light is a signal itself but not a component of the signal transduction pathway.
