When cellular respiration occurs within a cell, carbon dioxide is formed as a waste product. the carbon dioxide is transported out of the cell and absorbed by the blood stream. there, the carbon dioxide undergoes a chemical reaction and forms carbonic acid within the blood.

when the carbonic acid reaches the capillaries in the lungs, the enzyme carbonic anhydrase reverse the reaction and the carbonic acid is converted back to carbon dioxide and water.

which of the following would most likely happen if a person's body stopped producing carbonic anhydrase?

Which of the following is a common danger of commercial fishing?

Neelaredoxin is a 15-kda protein that is a gene product common in anaerobic prokaryotes. it has superoxide-scavenging activity, and it is constitutively expressed. in addition, its expression is not further induced during its exposure to o2 or h2o2 (silva, g., et al. 2001. j. bacteriol. 183: 4413–4420). which of the following statements best describes neelaredoxin synthesis? a-neelaredoxin is produced at all times; levels are constant even when exposed to o2 or h2o2.b-neelaredoxin is produced at all times; exposure to o2 or h2o2 increases expression.c-neelaredoxin is produced at all times; exposure to o2 or h2o2 decreases or prevents expression.d-neelaredoxin is only produced when there is exposure to o2 or h2o2.
