Question 1

The concentration of calcium inside a cell is 0.3%. The concentration of calcium outside the cell is 0.1%. How could the cell transport even more calcium to the inside?
◦ osmosis
◦ exocytosis
◦ active transport
◦ passive transport
◦ All of the answers are correct.

Question 2

When you place your finger on a sharp object (such as a tack), you quickly draw your hand away and develop a sensation of pain. Which types of channels are operating under these conditions to allow nerve conduction and subsequent muscle movement?
