EXAM 2 PRACTICE EXAM WITH THE CORRECT
ANSWERS 2026/2027
1. What are the two main laws of thermodynamics that govern energy transfers?
The second law of thermodynamics and the law of conservation of energy
The first law of thermodynamics and the law of entropy
The law of conservation of mass and the first law of
thermodynamics The first and second laws of thermodynamics
2. Patients with McArdle's Disease lack an enzyme in their livers that catabolizes
glycogen. Compared to an unaffected individual, what would you predict about the
blood glucose levels of a patient with McArdle's disease?
Blood glucose levels would be higher because they cannot break down
glycogen. Blood glucose levels would be lower because they cannot make
glycogen.
Blood glucose levels would be lower because they cannot break down glycogen.
Blood glucose levels would be normal, because glycogen is made up of amino
acids.
Blood glucose levels would be higher because they cannot make glycogen.
3. Describe the characteristics of an endergonic reaction as it relates to the
reaction C5H9NO4 + NH3 => C5H10N2O3 + H2O.
An endergonic reaction occurs spontaneously without energy input.
An endergonic reaction requires an input of energy and results in products that
have higher energy than the reactants.
