Premises:

Responses:

The primary mechanism by which Ca²⁺ acts as a signaling molecule is by increasing the net charge in the cytosol.

False

The extracellular concentration of Ca²⁺ is approximately 10⁴-fold higher than the concentration of Ca²⁺ in the cytosol.

True

Cytosolic Ca²⁺ concentration is kept low by the use of chelators such as EDTA.

The low cytosolic Ca²⁺ concentration sensitizes the cell to an influx of Ca²⁺, ensuring a rapid response to environmental stimuli.
