Across
- 5. Type of feedback that brings a system closer to homeostasis
- 7. Protein __ are enzymes that catalyze the transfer of a phosphate group from ATP to a protein or peptide substrate
- 9. signaling molecule that plays a vital role in action potentials and as secondary messengers inside cells
- 11. Type of cell signaling in which nearby cells are activated
- 13. Type of hormone that endorphins are
- 15. Signaling molecules that bind to receptors
- 19. Receptor type that allows polar ligands to bind
- 21. The acronym for the type of receptor (singular) whose main role is to mediate cellular response to external stimuli
- 22. Cell signaling is vital for multicellular organisms because it permits this
- 23. signaling molecules responsible for localized communication and travel via diffusion
- 24. __ Sensing permits bacterial colonies to respond to changes in population size by altering gene expression
- 25. The process of adding a phosphate group to a molecule to store/transfer free energy

- 1. Type of signalling path that neurotransmitters rely on
- 2. Receptor type that allows nonpolar ligands to bind
- 3. Type of hormone that Oestradiol is
- 4. Type of feedback that enhances the effect of the original stimulus
- 6. A series of secondary reactions that permit polar ligands to enact intracellular change
- 8. The process of increasing the strength of a signal via a cascade of reactions
- 10. Signal is converted to a signal that can be passed on
- 12. Type of cell signaling in which a cell communicates with itself
- 14. Signaling molecules produced by glands that can enact long-lasting change throughout the body
- 16. The most common secondary messenger
- 17. Type of cell signalling which a cell communicates over a long distance
- 18. signaling molecules that alter gene expression and play vital roles in immune response and cell growth/proliferation
- 20. Type of cell signalling in which a cell communicates directly to another cell (usually via a gap junction)
