The partial pressure of O2 in your lungs varies from 25 mm
Hg to 40 mm Hg. What mass of O2 can dissolve in 1.0L OF water at 25.0oC when
the O2 partial pressure is 40. mm Hg? Since the normal Water solubility of
oxygen at 25oC and pressure = 1 bar is at 40 mg/L water, the partial pressure
is only40 mmg Hg
Mass of 02 dissolve = (40 mmHg/760 mmHg)*( 40 mg/L) (1 L)
=2.10 mg O2 dissolved

Explanation:
Answer:
The answer to your question is: c) ATP
Explanation:
a) Carbon dioxide this molecule is a product of cell respiration so is very important for the cells but it isn't a form of energy cash, then this option is wrong.
b)Glucose: this molecule is used in the cell respiration process, from it the cell obtain ATP, but it isn't the energy cash for the cell.
c) ATP: this molecule is used by the cell to obtain energy, when an enzyme cuts off the phosphate bonds of this molecule it gets energy so this is the right answer.
d) Oxygen: oxygen is very important in the cell respiration process but It isn't usedas a energy cash.
