11. These channels open due to the depletion of intracellular calcium stores. 12. These interactions form connections between intracellular synaptic vesicles and fusion proteins. 13. These fatty acids likely activate FFA1, inducing an intracellular response. 14. ABC proteins transport various molecules across extra-and intracellular membranes. 15. To digest prey, it uses both extracellular and intracellular methods. 16. The study also showed an increase of intracellular calcium ion concentration. 17. Carboxyl-terminal ) with endophilins can induce intracellular vacuole formation. 18. ABC proteins transport various molecule across extra-and intracellular membranes. 19. Intracellular sodium increases and intracellular potassium decreases due to this inhibition.20. Intracellular sodium increases and intracellular potassium decreases due to this inhibition.
