You have a friend who lost 15 pounds of fat on a regimen of strict diet and exercise. How did the atoms from the fat molecules physically leave his body?
a
They were released as CO2 and H2O
b
They were converted to heat and then released

They were converted to urine and eliminated from the body
e
They were broken down to amino acids and eliminated from the body
a
They were released as CO2 and H2O

From CO2
