Biology
1 answer:
Irina-Kira [14]3 years ago
5 0

Answer:B

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,

Vera_Pavlovna [14]
An hypothesis is a possible explanation for a set of observations or answer to a scientific question. A supposition or proposed explanation made on the   
basis of limited evidence as a starting point for further  
 investigation. 
 And practically, an hypothesis is used as the basis for further experiments, where the hypothesis is rigorously tested under varying conditions. The hypothesis that is tested and modified under different conditions may become a general 
 theory
 .The hypothesis that has the least number of variables sufficient to explain the phenomenon is preferred.

Cellular respiration how cells harvest energy
velikii [3]

Answer:

Cellular Respiration: a process able to extract a large amount of energy from food molecules.  In eukaryotic cells oxygen is a required component. This metabolic process is the main reason that animals have elaborate gas exchange organs such as lungs, gills and other systems. The goal of these systems is, of course, to get access to oxygen and to get rid of carbon dioxide.
