Explanation:

This reaction demonstrated Bohr effect. it takes place in the cytoplasm of RBC , because this is the location of the enzyme carbonic anhydrase which catalyzed it .

The hydrogen ion and bicarbonate are transferred out of the RBC into plasma. Chloride ion diffused into the RBC to neutralize drop in pH(chloride shift).

The hydrogen ion is mobbed by haemoglobin in its buffer effect, while the carbonate is transferred to the lungs where it is broken down, to release C02 .85% of blood C02 is transported in this form .

The CO2 released out of the lungs , created a concentration gradient for influx of Oxygen into the lungs. This is the significance of this reaction.

In addition, Option D which involved direct reaction of C02 with Haemoglobin to form carbaminoheamoglobin is another reaction which takes place in the RBC. it is a reversible reaction where the C02 is transported to the lungs.10% C02 is tranported in this form,

Hunting in the darksome fish rely on senses beyond sight. in the darkness of the marianas trench, a fish called the rattail has an extremely sensitive sense of smell. the fish uses scent, rather than sight, to steer toward food. once it's near food, the rattail uses a special organ on the bottom of its chin to guide itself by feel.marine snowone staple of the deep sea diet is "marine snow," flakes of organic, edible substances that sink down from the upper ocean. animals at the ocean's bottom find sustenance in everything from the bodies of dead creatures to fecal matter. marine snow is diverse enough to support numerous species. for instance, several species of snails and worms feed exclusively on deceased whales.microorganismsthe deep sea is an intricate ecosystem, and even the ocean floor itself plays a part. hydrothermal vents are cracks in the sea floor where erupting magma mixes with ocean water to produce plumes of hot, sulfur-rich chemicals. some microbes can use these chemicals for energy, sustaining their existence and that of the animals who depend on their roles in the deep sea food chain.

You have just sequenced a new protein found in mice and observe that sulfur-containing cysteine residues occur at regular intervals. what is the significance of this finding? it will be important to include cysteine in the diet of the mice. cysteine residues are required for the formation of α helices and β pleated sheets. cysteine residues are involved in disulfide bridges that form tertiary structure. cysteine causes bends, or angles, to occur in the tertiary structure of proteins.
