Question

Quizplus · Accepted Answer

Cellular adhesion molecules (CAMs) are proteins located on the surface of cells that are involved in interactions with other cells or the extracellular matrix. CAMs can be categorized as selectins, integrins, immunoglobulin superfamily, and cadherins. Choice B includes selectins and integrins, which are both types of CAMs. Choice A includes DNA and RNA, which are genetic material and not CAMs. Choice C includes first and second messengers, which are signaling molecules and not CAMs. Choice D includes hormones and growth factors, which are signaling molecules and also not CAMs. Choice E includes insulin and glucagon, which are hormones and not CAMs.
