Th e central iron ion of cytochrome c changes between the +2 and +3 oxidation states as the protein shuttles electrons between complex III and complex IV of the respiratory chain (Section 5.10). Which do you expect to be larger: Fe2+ or Fe3+ ? Why?

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.

a. possible errors

d. new questions

explanation:

predictions and planning happen before. a summery comes after. errors you get after investigation and new questions propose what you can look for in the future.

the food storage products of chrysophytes are oils or the polysaccharide laminarin.   formerly classified as plants, the chrysophytes contain the photosynthetic pigments chlorophyll a and c all but the yellow-green algae also contain the carotenoid pigment fucoxanthin.
