Answer:
Fe2+ atom has a larger size than Fe3+.
Explanation:
The electron transport chain is important for the production of the ATP molecule. The oxygen molecule acts as the final electron acceptor in the electron transport chain.
The size of the cation is always small as compared with the parental atoms. Two electrons are removed from Fe2+ and three electrons are removed from Fe3+. This removal of electron increases the attraction force between the electron of the outermost shell and the nucleus and decreases the repulsion force between the electrons and thus decreases in size.
Answer:
The Atom is the basic unit of matter

The oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. This blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. From the left ventricle, the blood passes through the aortic valve to the aorta.
Biomolecules are important for living organisms and vital for cell structure and functioning. The cells are made up of biomolecules as their structural organization.
The four most abundant biomolecules are:
<u>Carbon, Oxygen, Nitrogen and Hydrogen</u>
The biomolecules can be explained as:
- The central biomolecules for life activities are these elements that contribute to major processes.
- The main building blocks like carbohydrate is composed of carbon, oxygen and hydrogen. They provide energy to the body by breaking into small molecules.
- Proteins are vital for cell signalling and transport. They are composed of amino groups consisting of nitrogen.
Therefore, carbon, nitrogen, hydrogen and oxygen are the most abundant biomolecules.
