Carbon dioxide can be transported through the blood via three methods. It is dissolved directly in the blood, bound to plasma proteins or hemoglobin, or converted into bicarbonate.
The majority of carbon dioxide is transported as part of the bicarbonate system. Carbon dioxide diffuses into red blood cells. Inside, carbonic anhydrase converts carbon dioxide into carbonic acid (H2CO3), which is subsequently hydrolyzed into bicarbonate (HCO3−) and H+. The H+ ion binds to hemoglobin in red blood cells, and bicarbonate is transported out of the red blood cells in exchange for a chloride ion. This is called the chloride shift.
Bicarbonate leaves the red blood cells and enters the blood plasma. In the lungs, bicarbonate is transported back into the red blood cells in exchange for chloride. The H+ dissociates from hemoglobin and combines with bicarbonate to form carbonic acid with the help of carbonic anhydrase, which further catalyzes the reaction to convert carbonic acid back into carbon dioxide and water. The carbon dioxide is then expelled from the lungs.
Answer:
It contains Uracil (U) instead of Thymine (T).
Reason for primer removal:
This is because of their uracil nucleotide which is absent in DNA. Instead of Uracil DNA contains Thymine nucleotide.
Explanation:
Primers:
Primers are a short sequence of RNA. These sequences attached to the 5' end are the requirement of DNA polymerase to start the process of replication.
Primer removal:
After replication, these short fragments of RNA are removed to replaced with DNA from the newly synthesized DNA strand.
Reason for primer removal:
This is because of their uracil nucleotide which is absent in DNA. Instead of Uracil DNA contains Thymine nucleotide.
Best Answer:
Because It contains Uracil (U) instead of Thymine (T).
Answer:
The correct answer will be option a and b.
Explanation:
The food is digested and absorbed in the small intestine, a long folded tube which lengths about 20 ft or 6m.
The small intestine increases the surface area for food absorption as they have circular folding as well as the finger-like projections called villi and microvilli in the lumen of the intestine. These villi help in absorption of the nutrients from the intestine.
Thus, option a and b are the correct options.
5/8 of 6 is 3.75
Translating this into hours it’s just 3 hours [and .75 of an hour which is 45 minutes]
Answer: 3 hours 45 minutes
Answer: Spectrin Protein Is a major component of the cortex in RBCs. mutations in this protein develop a from of anemia that can cause to RBCs to develop a flatened shape, making them extremely fragile.
