molecule with two joined rings that occurs in
nucleic acids and other cell constituents

Answer 3

Purine

Question 4

The metabolic process in which atmospheric 
 molecular nitrogen (N2) is reduced to 
 ammonia; carried out by cyanobacteria, 
 Rhizobium, and other nitrogen-fixing 
 procaryotes.

Answer 4

Pyrimidine

Question 6

The enzyme that catalyzes biological

nitrogen fixation.

Answer 6

Question 7

Enzymes that partially digest peptidoglycan
in growing bacteria so that the peptidoglycan
can be enlarged.

Answer 7

Autolysins

Question 8

The synthesis of glucose from
noncarbohydrate precursors such as lactate
and amino acids

Answer 8

Gluconeo genesis

Question 9

A series of chemical reactions that occurs as
part of the dark reactions of photosynthesis,
in which carbon is broken away from
gaseous carbon dioxide and fixed as organic
carbon in compounds that are ultimately
used to make sugars and starch as food.

Answer 9

Calvin cycle

removal of phosphate from molecules.

Answer 10

Phosphatase

Question 11

Reactions that replenish depleted

tricarboxylic acid cycle intermediates

Answer 11

anaplerotic reactions
