Question

question 9 (1 point)
which of the following components of the electron transport chain has the highest electronegativity?
oxygen
complex i
complex iii
complex iv

Explanation:

In the electron transport chain, oxygen is the final electron acceptor. Electronegativity is the tendency to attract electrons. Oxygen has a very high electronegativity and pulls electrons through the chain. Complexes I, III, and IV are protein complexes involved in electron transfer but have lower electronegativity than oxygen.

Answer:

oxygen
