BIO 390 Exam Questions And Answers (Verified And Updated) Why is it so important to keep Ca2+ levels low inside the cell, and how is this accomplished? - answerCa+ is the most commonly used 2nd messenger. The intracellular conc. Is very low and the extracellular conc. Is several times larger. A rise in Ca leads to receptor activation -> kinases -> and the phos. Of targets. How are levels of Ca2+ increased inside cells? - answer1. Voltage gated Ca channels on pm. 2. Ligand gated chan...
