(1) In the figure, ① process represents the photolysis of water, which occurs in the light reaction of photosynthesis, and ③ process represents the fixation of carbon dioxide in the dark reaction of photosynthesis.

(2) As can be seen from the figure, photoreaction provides [H] for dark reaction, and photoreaction can also provide ATP. Reaction to the dark.

(3) ⑤ in the figure represents the decomposition of glucose into pyruvate in the first stage of aerobic respiration; ⑥ It shows that pyruvate decomposes in the second stage of aerobic respiration to produce carbon dioxide and [H]; ② The process shows that [H] combines with oxygen to generate water in the third stage of aerobic respiration, and the place where this stage occurs is mitochondria (intima).

(4) All cells can breathe, and the first stage of anaerobic respiration and aerobic respiration is exactly the same, so living cells can generally perform the process shown in the figure.

So the answer is:

(1) immobilization of photoreactive carbon dioxide?

(2) adenosine triphosphate

(3) ⑤ ⑤ ② Mitochondria (intima)

(4)⑤
