Final answer:
Photosynthesis and cellular respiration are similar in several ways, including the presence of an electron transport chain and a series of redox reactions. However, they differ in terms of carbon fixation.
Step-by-step explanation:
Photosynthesis and cellular respiration are both essential processes in organisms that involve the transfer of energy, but they have some important differences. They are similar in that both pathways involve an electron transport chain, involve a long series of redox reactions, and have overall equations that involve the same substances but are reversed. However, the fixation of carbon is specific to photosynthesis, where carbon dioxide is converted into glucose, while cellular respiration involves the breakdown of glucose to produce energy in the form of ATP.
