B)sodium
C)calcium
D)iron

Question

Quizplus · Accepted Answer

Calcium ions are often used as second messengers in cells in response to the signaling of amino acid-based hormones. When a hormone binds to its receptor on the cell surface, it can trigger the activation of enzymes that produce calcium ions. These calcium ions can then bind to other proteins within the cell, leading to various physiological responses. Chlorine and sodium ions are not typically involved in second messenger signaling, while iron ions are more commonly involved in other cellular processes, such as oxygen transport.
