In aerobic respiration, the reductant (reducing agent) is ______________
and the oxidant (oxidizing agent) is ______________ with carbon dioxide
being one of the products and ______________ being the other product. The
conversion of ______________ energy to chemical energy generates ATP for
use in metabolism.
a) glucose; oxygen; water; metabolic

What happens to an organism if it is no longer able to convert energy from
the environment (nutrients or sunlight) into chemical energy?
a) it converts from being a heterotroph to an autotroph
b) it reaches equilibrium with the environment and dies
c) it reaches equilibrium with the environment and goes to sleep
, d) it uses 100 kj/mol of standard free energy to regenerate~CORRECT
ANSWER~b) it reached equilibrium with the environment and dies
Choose the two correct answers below that most accurately describe the
difference between the actual change in free energy and the standard
change in free energy.
a) the actual change in free energy is dependent on temperature
whereas the standard change in free energy is dependent on pressure but
not temperature
b) the standard charge of free energy is a function of time whereas the
actual change in free energy is a function of the rate constant
c) the standard change in free energy reflects the potential energy in
reactants and products independent of concentration whereas the actual
change in free energy is dependent on the concentration of reactants and
products under steady state conditions
d) the actual change in free energy changes in response to the
environment whereas the standard change in free energy is a constant for a
given reaction
e) there is no difference between the actual change in free energy and
t~CORRECT ANSWER~c) the standard change in free energy reflects the
potential energy in reactants and products independent of concentration
whereas the actual change in free energy is dependent on the concentration
of reactants and products under steady state conditions
