Question

fill in the blank question

an iron-containing (heme) protein electron carrier in the last phases of aerobic respiration is a(n)

Explanation:

Identify the key characteristics of the target molecule

• The question asks for an iron-containing (heme) protein electron carrier.
• It functions in the last phases of aerobic respiration (the electron transport chain).

Match characteristics to biological terms

• Proteins containing a heme group (iron-porphyrin ring) that serve as electron carriers in the respiratory chain are called cytochromes.
