Question

Hormones fall into two chemical groups based on their solubility: ____.
A)​hydrophilic and lipophobic
B)soluble and insoluble
C)lipophilic and lipophobic
D)hydrophilic and lipophilic
E)​acidic and alkaline

Quizplus · Accepted Answer

Hormones are classified into two groups based on their solubility: lipophilic (fat-soluble) and hydrophilic (water-soluble). Lipophilic hormones can diffuse through the cell membrane and bind to intracellular receptors, whereas hydrophilic hormones bind to cell-surface receptors and activate second messenger systems. Choice A is incorrect because lipophobic means "fat-repelling" and is not a relevant term for hormone solubility. Choice B is too vague and doesn't specify the type of solubility. Choice C is partially correct but only includes lipophilic and not hydrophilic hormones. Choice E is incorrect because hormone classification is not based on acidity or alkalinity.
