What would be the limiting factor for atp production by glycolysis in a strenuously exercising muscle that lacks lactate dehydrogenase? increased acidity from lactic acid, causing muscle damage the supply of nad+ the supply of adp the supply of pyruvate the supply of

the supply of NAD+.

Explanation:

Glycolysis is the first collection of reactions in the metabolism of glucose in muscle cells. This process creates glucose-based pyruvate while producing a few molecules of ATP and NADH. On the other hand, lactate dehydrogenase is an enzyme that is used to extract pyruvate from lactate in the fermentation process.

Muscles would lack sufficient oxygen during strenuous exercises and would therefore proceed to the formation of anaerobic lactate, which uses the enzyme, lactate dehydrogenase. If this enzyme is absent in the process, there would be no production of lactate and no replenishment of NAD+ levels. This would ultimately result in a limited supply of NAD+, which is needed in some glycolytic reactions  as electron recipients.

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.
