Both processes are regulated by Ca 2+ binding to C2A and C2C domains ( … WebMar 28, 2024 · Nowadays, it is known that the membrane lipids are responsible for the overall cell shape. The charge and size of the head group as well as the number, length and saturation of the acyl chains are all important factors determining membrane symmetry. For example, large, charged head groups are more likely to form curved structures. shiv storm lyrics
