Which of the following is true? A) A protein with a manganese ion is key to the conversion of O₂to water B) The electron transport chain in photosynthesis is identical to the one in mitochondria C) Parts of the electron transport chain in photosynthesis are similar to the electron transport chain in mitochondria D) Photosynthesis is the exact opposite of respiration

Question

Quizplus · Accepted Answer

Parts of the electron transport chain in photosynthesis, specifically the protein complexes involved in electron transfer, are similar to those in the electron transport chain in mitochondria. However, there are also significant differences in the specific proteins and cofactors involved in each process. Option A is false as there is no known protein with a manganese ion involved in the conversion of O₂to water. Option B is false as there are significant differences in the electron transport chain of photosynthesis and that of mitochondria. Option D is false as photosynthesis and respiration are not exact opposites; they involve some similar processes, but also have some key differences.
