PCB 3023: Sotero Exam 3 | UPDATED Questions with 100% Verified
Answers
Question:
Changes is free energy during glycolysis in human
erythrocytes:
Answer:
these are the changes in the total energy in the cell (delta G), which is the energy that can
be converted to do work. They are not the energy changes for the individual in the
pathway.
Question:
The second law of thermodyn
Answer:
Increasing order in the cell generates heat, which dissipates and causes increased
disorder outside the cell.
Question:
Second law of thermodynamics means the tendency?
Answer:
toward disorder
Question:
Classic example of 2nd thermodynamics
Answer:
DISORDER IN THE BEDROOM SPONTANEOUSLY OCCURS
Question:
To decrease disorder,
Answer:
energy must be spent
Question:
1st Law of Thermodynamics
, Answer:
energy can neither be created nor destroyed, only transferred
Question:
3rd law of thermodynamics
Answer:
as system approaches absolute zero, all processes cease and the entropy of the system
approaches a minimum value.
Question:
Energy can be defined as
Answer:
The capacity to perform work. If a reaction results in negative change in the free nervy of
the molecule then the reaction increases disorder, and is therefore spontaneous.
Question:
Energy is released:
Answer:
spontaneous reaction (exergonic)
Question:
Energy is consumed:
Answer:
nonspontaneous reaction, (endergonic)
Question:
What happens when building a more complex (more ordered)
molecule?
Answer:
Entropy in the cell is decreased, while breaking bonds increases it.
Question:
A dehydration synthesis is?
, Answer:
a non-spontaneous reaction.
Question:
With a dehydration synthesis it results in an increase in?
Answer:
molecule order
Question:
The reverse reaction of dehydration synthesis is?
Answer:
Hydrolysis
Question:
Hydrolysis releases _____ and is therefore ______.
Answer:
energy, spontaneous
Question:
The higher the difference in energy between the reactants and
the products of a reaction,
Answer:
the more overall (net) reaction will tend to go in one direction
Question:
X has less energy than Y, therefore
Answer:
the favored direction of the reaction will be toward X
Question:
Note that the ___ transformation will also occur but less
frequently.
