Exam 11: Anabolism the Use of Energy in Biosynthesis

Purines and pyrimidines are precursors for synthesis of

Symbiotic nitrogen fixation can consume up to __________% of the ATP generated by the host plant.

In order to synthesize new peptidoglycan for bacterial cell walls, the existing walls must be partially digested by __________ to provide acceptor ends for the new synthesis.

Although most autotrophic microorganisms fix carbon dioxide using the Calvin-Benson cycle, this pathway is absent in the Archaea.

Anabolic and catabolic pathways use different cofactors for similar reactions.

Which of the following is not a phase of the Calvin Cycle?

Microorganisms assimilate large amounts of all of the following except __________ into organic molecules.

Large numbers of small monomeric molecules join together to form large molecules that are known as:

Which of the following is not generally true about fatty acids produced by microorganisms?

Nitrogen fixation is used to form ATP, which is then used for energy reserves.

A purine or pyrimidine that is attached to a sugar, either ribose or deoxyribose, to which is attached one or more phosphate groups is called a:

__________ is the carrier molecule required to transport peptidoglycan subunits to the location where they will be incorporated into the growing bacterial cell wall.

The reduction of atmospheric nitrogen to ammonia is called

In the biosynthesis of nucleotides, pyrimidines are assembled starting with ribose-5-phosphate while ribose-5-phosphate is added after synthesis of the nitrogenous base for purines.

In the synthesis of amino acids the addition of the amino nitrogen usually occurs __________ the synthesis of the carbon skeletons.

Bacteria can synthesize unsaturated fatty acids only under anaerobic conditions.

The process of carbon dioxide fixation refers to

Which of the following cofactors is very important in the synthesis of purines?

Nitrogen fixation depends on the enzyme nitrogenase which is produced by some

Nongrowing cells continuously degrade and resynthesize cellular molecules during a process known as cellular turnover.
