At the doctor’s office, the doctor drains the abscess and takes a sample for culturing. she also prescribes some broad-spectrum antibiotics to treat the obvious infection. a couple days later, the doctor tells sam that his wound contained a number of bacteria including pasteurella multocida. when the dog bit sam’s arm p. multocida entered the wound and started to establish an infection. in order to do so, the bacteria have to grow, which requires energy. one of the most common energy sources used by bacteria is glucose. why is glucose such a good source of energy for bacteria?

a. glucose contains six oxygen atoms, which can be used for oxidative phosphorylation and the generation of many atp molecules.
b. glucose is a highly reduced compound, containing many carbon-hydrogen bonds and a lot of potential energy.
c. glucose contains six carbon atoms, which can be quickly incorporated into organic cellular constituents needed for growth.
d. glucose is a highly oxidized compound, containing many carbon-hydrogen bonds and a lot of potential energy.

The correct answer is option b. "Glucose is a highly reduced compound, containing many carbon-hydrogen bonds and a lot of potential energy".

Explanation:

Glucose is the preferred source of energy for many microorganisms, including most bacteria. The reason behind this adaptation is that glucose is a highly reduced compound, containing many carbon-hydrogen bonds and a lot of potential energy. Reduction of glucose is achieved through different metabolic pathways using enzymes as aldehyde reductase, and its carbon-hydrogen bonds breakdown releases a lot of potential energy. These two properties makes glucose a good source of energy for the cells.

explanation:

transcription is a process in which information is rewritten. it is something our cells must do, in a more specialized and narrowly defined way. in biology, transcription is the process of copying out the dna sequence of a gene in the similar alphabet of rna. it needs to happen in the nucleus because that's where the dna is. dna is always inside the nucleus unless the cell is dividing.

transcription is the first step in gene expression, which involves copying a gene's dna sequence to make an rna molecule. transcription is performed by rna polymerases. it has three stages: initiation, elongation, and termination. rna molecules must be processed after transcription in eukaryotes.

explanation:

long version:

the protein synthesis consists two processes which are, transcription and translation. transcription takes place in the nucleus. it uses dna as a template to make an rna molecule. rna then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. transcription is the first part of the central dogma of molecular biology: dna → rna. it is the transfer of genetic instructions in dna to messenger rna (mrna). during transcription, a strand of mrna is made that is complementary to a strand of dna.  

these three stages are:

  initiation: in which   is the beginning of transcription.occuring when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

    elongation: in which is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

    termination: in which is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
