[CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
|
The erythrocyte obtains energy through various metabolic pathways that allow the formation of four fundamental substances for the function of hemoglobin. These are:
|
|
adenosine triphosphate
|
|
|
2, 3 diphosphoglycerate
|
|
|
Reduced Nicotinamide Dinucleotide
|
|
|
Reduced Nicotinamide Mononucleotide
|
Explanation:
Detailed explanation-1: -Erythrocyte metabolism is unique due to the absence of mitochondria. Therefore, they cannot generate ATP by oxidative phosphorylation. The energy source for the erythrocyte is D-glucose’.
Detailed explanation-2: -One of the major reaction pathways in RBC is the Embden-Meyerhof in which a series of enzymes convert glucose anaerobically into usable energy: adenosine triphosphate (ATP).
Detailed explanation-3: -Erythrocytes rely on metabolic processes to maintain cellular shape and flexibility and to keep essential constituents in reduced, active form.
