Signaling between cells that are in direct contact (e.g., plasmodesmata)?
Answer: Juxtacrine Signaling
Signaling where a cell targets a nearby cell (e.g., neurotransmitters)?
Answer: Paracrine Signaling
Long-distance signaling using hormones via the bloodstream?
Answer: Endocrine Signaling
A cell signaling to itself?
Answer: Autocrine Signaling
A signaling molecule that binds specifically to a receptor?
Answer: Ligand
The three stages of cell signaling?
Answer: Reception, Transduction, Response
Process where a signal is converted into a cellular response via a pathway?
Answer: Signal Transduction Pathway
An enzyme that transfers phosphate groups from ATP to a protein (turning it "on")?
Answer: Protein Kinase
Small, non-protein, water-soluble molecules that spread a signal (e.g., cAMP, Ca²⁺)?
Answer: Second Messengers
The "multiplying" of a signal inside the cell; one ligand leads to many responses?
Answer: Signal Amplification
Second messenger made from ATP by adenylyl cyclase?
Answer: cAMP (cyclic AMP)
Mechanism that maintains homeostasis by returning a system to a set point?
Answer: Negative Feedback
Mechanism that amplifies a response to move further away from the set point?
Answer: Positive Feedback
The non-dividing phase where a cell spends 90% of its life?
Answer: Interphase
Phase of interphase where DNA is replicated?
Answer: S Phase (Synthesis)
Division of the nucleus?
Answer: Mitosis
Division of the cytoplasm?
Answer: Cytokinesis
Play it as a class game
Play this set opens it in splycr, where you can host it for your class straight away. Hosting needs no account: put the room code on the projector, and students join from a phone with the code and their first name. Each question plays as multiple choice, and the three wrong options are other answers from the same set.
