WebFor the first time, other recent studies have detected the existence of a Na+-dependent, carrier-mediated mechanism for biotin uptake at the apical membrane of colonocytes, which could theoretically mediate absorption of the biotin synthesized by colonic microflora. WebLocated in the inner membrane of the mitochondria, ATP Synthase is involved with the electron transport chain within the same membrane. The 4 complexes of the electron transport chain create a concentration gradient of protons across the membrane; ATP Synthase is then able to utilize this concentration gradient to produce ATP.

WebMost cells expend most of their energy, in the form of adenosine triphosphate (ATP), to create and maintain an uneven distribution of ions on the opposite sides of their membranes. The structure of the plasma membrane contributes to these functions, but it also presents some problems. The most direct forms of membrane transport are passive.

WebMembrane ion channels of the calcium homeostasis modulator (CALHM) family promote cell–cell crosstalk at neuronal synapses via ATP release, where ATP acts as a neurotransmitter.
