A particular organism converts Fe3 to Fe2 during anaerobic respiration. In this case, is an electron . Choose one: A. Fe2 ; acceptor B. Iron cannot be oxidized or reduced. C. Fe3 ; acceptor D. Fe3 ; donor

C

Explanation:

All organisms including anaerobic organisms undergo respiration. The difference in the cellular respiration of aerobes and anaerobes is that oxygen is the final electron acceptor in aerobic cellular respiration while another element is the electron acceptor in anaerobic respiration.

This process of transferring electrons in cellular respiration occurs during the electron transport chain (ETC). According to the question, the anaerobic organism converts Fe3 to Fe2 during respiration, meaning that iron is its final electron acceptor during ETC.

In chemistry, an electron acceptor accepts an electron (e-) and become reduced itself. In this case, the oxidation state of iron reduced from +3 to +2 because it accepted one electron (e-).

answer; /// i believe that the correct answer is ( monophasic ); ethinyl estradiol- ethynodiol diacetate is a monophasic oral contraceptive agent; ///

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )
