El sarcolema, o membrana plasmática de una célula muscular, ayuda a mantener un gradiente de concentración de iones de calcio entre el citoplasma de la célula muscular y el líquido extracelular. Cuando una célula muscular recibe una señal para contraerse, el calcio (Ca+2) se mueve a favor de este gradiente y pasa del espacio extracelular hacia el citoplasma de la célula. ¿Cuál de los siguientes es el mecanismo más probable por el cual el Ca+2 atraviesa el sarcolema durante la contracción de la célula muscular? a. El Ca+2 fluye a través de acuaporinas
b. El Ca+2 pasa por canales proteicos de la membrana
c. El Ca+2 se transporta por proteinas periferales

Molecules like glucose and amino acids are not lipid soluble, so cannot cross the cell membrane by simple diffusion. instead, they are shuttled across by carrier proteins in the membrane from high to low concentration. does this process require energy from the cell? this is an example of what type of molecular movement?
