<h2>The given statement is true</h2>
Explanation:
Iron absorption occurs in the duodenum and upper jejunum of small intestine
- At physiological pH ferrous iron is rapidly oxidized to the insoluble ferric form
- Gastric acid lowers the pH in the duodenum which enhances the solubility and uptake of ferric iron
- Once iron gets inside the enterocyte it can be stored as ferritin;Ferritin is a hollow spherical protein which helps in storage and regulation of iron levels within the body
- Ferritin molecule have ferroxidase activity which helps in the mobility of Fe2+ out of the enterocyte by ferroportin
- Transferrin is the major iron transport protein which transports iron through blood
- Fe3+ binds to transferrin so Fe2+ transported through ferroportin must be oxidized to Fe3+
- Fe2+ needs to be oxidized first so that it can be transported through ferroportin
- Once iron gets inside the cell it can be used for various cellular processes

The synthesis<span> of </span>proteins<span> takes two step, transcription and translation. Transcription takes the information encoded in DNA and encodes it into mRNA, which heads out of the cell's nucleus and into the cytoplasm. During translation, the mRNA works with a ribosome and tRNA to synthesize </span>proteins<span>.</span>

Answer:
Why would newborns be cashing in so many red blood cells?
The possibe sources for the hematocrit are influx of RBC from other sources to the Fetus. e.g., leakage of RBC from the twin child in case of twin pregnancy, possible overproduction of RBC in the fetus,Leakage of some RBC through the umbilical cord to the child close to delivery.
Why would noenates need so much antioxidants
The increased oxidative stress in neonates with Jaundice, leads to loss of antioxidants and ascorbic acids.The loses disrupted their metabolism and therefore the natural ability to fight the oxidative stress.
Consequently,increase in the oxidative stress couple with lack of antioxidant leads to neural cell death.
Therefore, antioxodant is needed to prevent neural cell death and to withstand oxidative stress.
