<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
Answer:
Theory
Explanation:
It is a substantiated explanation because of the set of facts and observations on the experiment.
A cycadophyta is a biological dividsion, and within this,nthree are three families, and these are; Cycaclaceae, Strangeriaceae and Zamiceae. The plants of these are seed plants, which generally have characteristics, such as a stout, short and tough trunk made of wood, with a crown like span of evergreen leaves, with a cone shape protruding from the centre of the tree.
Sorry, I wasnt able to attach an image, but if you google cycadophyta, this is what they look like.
Sorry for the inconvenience, hope this helps
Despite the similarities, methylene chloride (or dichloromethane) is superior to ethylene chloride as an extraction solvent because the boiling point of methylene chloride is lower than the boiling point of ethylene chloride, which allows it to be removed more easily.
