Individuals with cystic fibrosis are plagued by increased production of mucus. this excess mucus has a variety of effects on the body, including decreased production of pancreatic enzymes and blockage of the pancreatic ducts that secrete enzymes. describe how impaired pancreatic enzyme secretion affects digestion.

The digestion process will slow down.

Explanation:

Pancreas is located on the abdomen just behind the stomach. Pancreas releases various enzymes that helps in the digestion of proteins, fats and carbohydrates.

The impairment and deficiency of the pancreas enzyme affects the digestion process as the food is not completely digested and broken down into simple amino acids. The improper digestion can cause severe gastric problems in the individual.

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.
