Hormones are ligands that bond to cells and carry a specific receptor. The ligand bonds its receptor to form a complex that acquires a purpose. The ligand triggers a change in the receptor, which activates a potential biological function. Cells that do not exhibit the receptor never receive the signal.

What is the difference between pheromone and hormones?
pheromones are special female hormones
Why can steroid and thyroid hormones but not amino acid-based hormones move across cell membranes?
b/c steroid and thyroid hormones are fat soluble
What is the role of quinoline in the hydrogenation of alkynes?
Quinoline "poisons" the Lindlar catalyst, thereby enhancing its selectivity. This prevents the hydrogenation reaction from going from the alkyne to the alkane, and instead from the alkyne to the alkene.
Are peptide bonds weak?
hydrophilic "water loving" Hormones 2 groups- -Peptides (short protein)- such as insulin - Catecholamines: hormones epinephrine and noreepinephrine Low lipid solubility, High water solubility Lipophilic "Fat Loving" Hormones 2 Groups - Thyroid hormones - Steroid Hormones --> sex hormones such as testosterone High lipid solubitilty, poorly soluble in water Cholesterol precusor (molecule is not a hormone)
Can baking soda balance your hormones?

What are selectivity barriers in communication?
The audience is not able to absorb all the information coming from a variety of sources; so the audience pick up information on selectively. The selectivity is affected by timing, context, and the degree of uniqueness of information
What is considered as very important in the movement of molecules through protein channels?
selectivity
External environmental factors on perceptual selectivity?
External environmental factors such as noise level, lighting, temperature, and distractions can influence perceptual selectivity by affecting our ability to focus on specific stimuli and filter out irrelevant information. For example, a noisy environment can increase cognitive load and reduce attention allocation, leading to decreased selectivity. Similarly, variations in lighting can impact visual perception and the ability to discern details accurately. Overall, these external factors can impact our ability to selectively attend to relevant stimuli and process information effectively.
What is Darwin's theory selectivity?
Darwin said that only the fittest will survive and these then pass their "fit" genes on.
