Which allows cells ton d* +8m dvmprcndba 7,q9uw33r),uny stick touq 8o y 4jh2t eswb,(*te;je;qgether to form tissues?
A. Cell cohesion molecules
B. Channel proteins
C. Cell adhesion molecules
D. Cell-cell junction molecules
参考答案: C
本题详细解析:
Cell adhesion molecules (CAMs) are cell surface proteins that help cells bind together and maintain the structural integrity of tissues, Choice C is therefore correct. Choice A is incorrect as it is a made up term. Choice B is incorrect, as channel proteins allow molecules to move across the plasma membrane using facilitated diffusion. Choice D is incorrect, as cell-cell junctions are specialised structures that physically connect adjacent cells, facilitating communication and coordinating cellular activities within tissues. Cell-cell junctions can only be formed after the process of cell adhesion has occurred.
