Metabolic acidosis can occur as a side effect of taking acetazolamide because: Select one: a. bicarbonate ions are wasted when sodium is excreted into the urine, leaving behind acidic metabolic waste products that need to be neutralized. b. chloride ions are wasted when sodium is excreted into the urine, leaving behind acidic metabolic waste products that need to be neutralized. c. bicarbonate ions are wasted when sodium is reabsorbed into the tubule as it attracts hydrogen ions. d. chloride ions are wasted when sodium is reabsorbed into the tubule as it attracts hydrogen ions.

a. bicarbonate ions are wasted when sodium is excreted into the urine, leaving behind acidic metabolic waste products that need to be neutralized.

Explanation:

Metabolic acidosis is an electrolyte disorder characterized by a pH of less than 7.40 and low bicarbonate (HCO3) levels in the blood. This disease may be due to 1-an increasing acid production, 2-loss of HCO3 (which acts as an acid buffer agent), and 3- by a decreasing ability of the kidneys to maintain normal acid levels. The kidneys contribute to maintaining the acid–base balance by excreting hydrogen ions (H+) into the urine and absorbing HCO3 from the urine. In metabolic acidosis, kidneys are unable to remove enough acid and conserve sodium ions (Na+), which is normally done by excreting ammonia in the urine.

step 1: initiation

initiation is the beginning of transcription. it occurs 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.

step 2: elongation

elongation 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.

step 3: termination

termination 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.
