Indicаte whether eаch оf the fоllоwing stаtements regarding calcium signaling is likely to be true or false. Calmodulins are cytoplasmic signaling proteins that sense the change in cytoplasmic [Ca2+] and relay the signal to downstream factors. Each calmodulin has two calcium-binding sites. [1] Calcium pumps are only present in the plasma membrane. [2] The ER is not involved in calcium signaling. [3] Right after fertilization, the increase in cytoplasmic [Ca2+] in the egg cell results in the change in the surface structure of the egg, which helps to prevent polyspermy. [4]
