Questions with Solved Solutions.
According to the Second Law of Thermodynamics, - Answer when energy changes forms the
amount of useful energy decreases
The change in free energy is calculated by the following formula: - Answer ΔG= ΔH - T(ΔS)
Which of the following reactions will always be spontaneous? - Answer Enthalpy decreases,
entropy increases
When glucose monomers are joined to form a cellulose polymer, the changes in free energy,
enthalpy, and entropy are: - Answer +ΔG, +ΔH, -ΔS
(T/F): Enzymes decrease free energy in the reacion as well. - Answer False
In competitive inhibition, adding more substrate - Answer can eventually overcome
inhibition by replacing inhibitors
Allosteric regulators can: - Answer Either activate or hinhibit an enzyme by binding to its
other site

Answer Loses electrons and Loses energy
What kind of reaction is cellular respiration? - Answer Exergonic
Where does Oxidative Phosphorylation occur? - Answer Inner mitochondrial membrane
Where does the citric acid cycle occur? - Answer Mitochondrial matrix
(T/F): Fermentation makes more ATP than oxidative phosphorylation. - Answer False
What is the big picture of aerobic respiration? - Answer Using energy from glucose to create
H+ gradient making ATP and reducing O2.
