Explanation:
Answer:
<h2>Endoplasmic reticulum</h2>
The endoplasmic reticulum is a network of membranes within the cell through which proteins and other molecules move. Proteins assemble into organelles called ribosomes. When proteins are destined to be part of the cell membrane or exported out of the cell, ribosomes assemble them and add them to the endoplasmic reticulum, giving it a rough appearance.

Answer:
RBCs' production is controlled by erythropoietin.
Mature RBCs are released into the bloodstream after approximately seven days RBCs are produced in the bone marrow
Explanation:
The hormone erythropoietin is produced and released in the bloodstream by peritubular interstitial cells of kidneys. The function of erythropoietin is to increase the number of the precursors of red blood cells and thereby to stimulate the production of red blood cells in the bone marrow. When the oxygen supply to body cells is reduced, the hormone erythropoietin stimulates the development of proerythroblasts into reticulocytes and thereby increases the RBC production.
RBCs are produced by the process of erythropoiesis and take about seven days to become mature and to be released in circulation to serve the function of oxygen delivery. The maturation of RBCs also includes the loss of most of the organelles such as the nucleus and mitochondria to accommodate hemoglobin protein. The life span of circulating RBCs is about 100-120 days.
Because for each glucose molecule there are two pyruvic acid molecules entering the system, two ATP molecules are formed. Also during the Krebs cycle<span>, the two carbon atoms of acetyl-CoA are released, and each forms a carbon dioxide molecule.</span>
