Question

FILL THE BLANK. Complete the following passage on the comparison of photosynthesis and cellular respiration by filling in the missing words. Despite their differences, photosynthesis and cellular respiration also share several similarities. Both photosynthesis and cellular respiration use a(n)_______ and have a _______ dependent protein complex known as_______ , that catalyses synthesis of energy in the form of ATP. While mitochondrial electrons come from the oxidation of________ , in chloroplasts electrons come from the oxidation of________ . In photosynthesis, the ATP is predominantly used to support carbohydrate synthesis by the________ , whereas the ATP generated by cellular respiration provides energy for a variety of cellular functions.

Answer 1

Both photosynthesis and cellular respiration use an electron transport chain and a light-dependent protein complex to produce ATP. In photosynthesis, ATP supports carbohydrate synthesis, while in cellular respiration, it provides energy for cellular functions. Oxidation of water in photosynthesis and NADH and FADH2 in cellular respiration provide the required electrons.

Step-by-step explanation:

Despite their differences, photosynthesis and cellular respiration also share several similarities. Both photosynthesis and cellular respiration use a(n) electron transport chain and have a light dependent protein complex known as Cytochrome b6f complex, that catalyses the synthesis of energy in the form of ATP. While mitochondrial electrons come from the oxidation of NADH and FADH2, in chloroplasts electrons come from the oxidation of water. In photosynthesis, the ATP is predominantly used to support carbohydrate synthesis by the Calvin cycle, whereas the ATP generated by cellular respiration provides energy for a variety of cellular functions.
