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-).

the core of the sun is so hot and there is so much pressure, nuclear fusion takes place, hydrogen is changed to helium. nuclear fusion creates heat and photons. when the heat reaches the earth it warms the molecules of the atmosphere, and they warm other molecules and so on.
