Q25P Cyanobacteria contain carboxysom... [FREE SOLUTION]

Chapter 19: Q25P (page 662)

Cyanobacteria contain carboxysomes, which consist of a protein shell that encloses RuBP carboxylase and is permeable to small anions such as ${HCO}_{3}^{鈭�}$ .Explain why carbonic anhydrase is also a component of the carboxysome.

Short Answer

Expert verified

Carbonic anhydrase is an enzyme that is a component of the carboxysome, as it catalyzes the reaction of conversion of ${HCO}_{3}^{鈭�}$ to ${CO}_{2}$ .

Step by step solution

Function of RuBisCO enzyme

Ribulose-1,5-bisphosphate carboxylase enzyme catalyzes the carboxylation of RuBP (ribulose-1,5-bisphosphate) with ${CO}_{2}$ as the substrate.

Reason behind the carboxysome being a component of RuBP

Carboxysomes are micro compartments in bacteria containing the enzyme ribulose-1,5-bisphosphate carboxylase. Its shell is permeable to ${HCO}_{3}^{鈭�}$ . It also contains carbonic anhydrase enzyme because this enzyme is responsible for the conversion of ${HCO}_{3}^{鈭�}$ to ${CO}_{2}$ , which is the major substrate for RuBP carboxylase enzyme.

Hence, carbonic anhydrase catalyzes the reaction in the conversion of ${HCO}_{3}^{鈭�}$ to ${CO}_{2}$ , which is the substrate for RuBP carboxylase.
