Different cells can have vastly different cell sizes; but as an approximation, let us assume that all cells in the body are spheres that are 16 micrometers (1.6 x 10-5m) in diameter. The current best estimate in the scientific literature is that there are approximately 40 trillion human cells (4 × 10¹3 cells) in an adult human body. First, calculate the volume of the human body based on these estimates. Does the answer seem reasonable?

Question

Many cells in the human body maintain an electric potential difference across their cellular membranes, typically through the use ion-specific pumps and
channels that generate an excess of negative charges on the inside of the cellular membrane and an excess of positive charges on the outside. Let us
estimate the total energy stored in the human body by this type of charge separation.

Different cells can have vastly different cell sizes; but as an approximation, let us assume that all cells in the body are spheres that are 16 micrometers
(1.6 × 10-5m) in diameter. The current best estimate in the scientific literature is that there are approximately 40 trillion human cells (4 × 10¹³ cells) in
an adult human body. First, calculate the volume of the human body based on these estimates. Does the answer seem reasonable?
