Human Metabolism

Being described as the most complicated machine ever encountered by humans, the human body and the cell metabolism is nothing less than a wonder. Metabolism is the set of life-sustaining chemical reactions within organisms.

Question

to diffuse through a 0.200-mm-thick tear layer on the cornea.
(b) How much time is required to diffuse 0.500 cm³ of
oxygen to the cornea if its surface area is 1.00 cm² ?
