2. Which description is true of Gibbs free energy? Select all that apply.
contributes to the overall system enthalpy
contributes to overall system entropy
allows for exergonic and spontaneous reaction when its value is less than 0
is available for work in a system when pressure and temperature are uniform throughout the system
goes to zero when a system is in equilibrium
3. What kinds of work are central to a cell’s metabolism? Select all that apply.
A. Transport work
B. Chemical work
C. Electrical work
D. Mechanical work
E. Exergonic work
4. What kind of reaction is indicated by a Gibbs free energy of <0? (one answer)
exergonic and nonspontaneous
Endergonic
Nonspontaneous
exergonic and spontaneous
5. What is true about a multiphase feedback inhibition? Select all that apply.
The reaction can only be inhibited during the first or second phases.
Once the reaction is inhibited, it cannot be restarted.
Enzymes stop or slow the reaction.
Feedback inhibition will not occur in the presence of substrate.
Feedback inhibition balances substrate and enzymes during a reaction.

Asample of digestive juice was removed from the stomach of a pig. the juice was placed in a test tube along with some grains of wheat. a second test tube was set up containing an equal number of wheat grains, with distilled water rather than digestive juice. the test tubes were kept for 8 hours at 40 degrees c. after 8 hours, the grains inside the digestive juice had broken into tiny particles. the grains of wheat, in the water, were wet but otherwise unchanged. what is the control group?
