, 1. are bounded by a plasma membrane
2.have a cytosol containing metabolites, coenzymes, inorganic ions, and
enzymes;
3.and have a set of genes contained within a nucleoid (bacteria and
archaea) or nucleus (eukaryotes).
what are diasteromers
Which of the following is true about the two molecules shown below?
A. They have the same configuration.
B. They are cis-trans isomers.
C. They are enantiomers of each other.
D. They are diastereomers of each other.

Diastereomers are pairs of stereoisomers that are not mirror images of
each other. (see p. 16
Exergonic and endergonic reactions differ in that
A. exergonic reactions have a positive free energy change (ΔG is positive) and
endergonic reactions have a negative free energy change (ΔG is negative).
B. exergonic reactions require an input of energy and endergonic reactions release
free energy.
C. exergonic reactions produce products with less free energy than the reactants;
endergonic reactions produce products with more free energy than the reactants.
D. exergonic reactions consume more free energy than is released and endergonic
reactions release more free energy than is consumed.
