BIO 102 Objective Question

Question

What cellular function is associated with iron (Fe) in fungal cells?
Options
A Enzyme activity and cell structure
B Energy transduction and nucleic acid structure
C Heme-proteins and cytochromes
Correct Answer
D Ionic balance and enzyme activity
Correct Answer

Option C is the correct answer.

Detailed Explanation

Iron (Fe) is required by fungal cells for heme-proteins and cytochromes. Iron is taken up as ferric salts (Fe3+), chelated by siderophores, and released as Fe2+ within the cell for these critical functions.

Hint

Think about the role of iron in electron transport chains and oxygen-binding proteins.
