Question 1

If a bacterial cell encounters unfavorable environmental conditions, then its metabolism will begin to slow until it eventually transforms into an inactive, dormant state.This survival mechanism is known as:

Accepted Answer

A)  polymerization. 
B)  oxidation. 
C)  respiration. 
D)  sporulation.

Question 2

The term used when oxidative phosphorylation uses oxygen as the terminal electron acceptor is:

Accepted Answer

A)  substrate-level phosphorylation. 
B)  fermentative metabolism. 
C)  anaerobic respiration. 
D)  aerobic respiration.

Question 3

A pathway that generates ATP by substrate-level phosphorylation that does not require oxygen and produces various end products, including alcohols, acids, carbon dioxide, and hydrogen, is:

Accepted Answer

A)  substrate-level phosphorylation. 
B)  fermentative metabolism. 
C)  oxidative phosphorylation. 
D)  aerobic respiration.

Question 4

Transduction is defined as the:

Accepted Answer

A)  change of the bacterial genotypes through the exchange of DNA from one cell to another. 
B)  internal change in the original nucleotide sequence of a gene or genes within an organism's genome. 
C)  process by which genetic elements such as plasmids and transposons excise from one genomic location and insert into another. 
D)  mechanism that is mediated by viruses, by which DNA from two bacteria may come together in one cell, thus allowing for recombination.

Question 5

Recombination is defined as the:

Accepted Answer

A)  change of the bacterial genotypes through the exchange of DNA from one cell to another. 
B)  internal change in the original nucleotide sequence of a gene or genes within an organism's genome. 
C)  process by which genetic elements such as plasmids and transposons excise from one genomic location and insert into another. 
D)  uptake of free DNA from the environment and recombination with the recipient's homologous DNA.
