Answer C

Answer analysis test question analysis: Yeast performs aerobic respiration under aerobic conditions and anaerobic respiration under anaerobic conditions. The locations of the three stages of aerobic respiration are the cytoplasmic matrix, mitochondrial matrix, and mitochondrial inner membrane. Both stages of anaerobic respiration occur in the cytoplasmic matrix. The test tube No. 1 is a cytoplasmic matrix, which will no longer decompose pyruvate, alcohol and CO2 in the presence of oxygen; the test tube No. 2 is a cytoplasmic matrix, which can oxidatively decompose glucose into CO2 and CO2 in the absence of oxygen. Alcohol; Test tube No. 3 contains mitochondria, which can decompose pyruvate to produce CO2 and H2O in the presence of oxygen; test tube No. 4 contains mitochondria, which do not contain enzymes that decompose glucose and do not decompose glucose; test tube No. 5 contains complete yeast Bacterial cells can completely oxidize and decompose glucose into CO2 and H2O in the presence of oxygen; test tube No. 6 contains complete yeast cells, which can oxidize and decompose glucose into CO2 and alcohol in the absence of oxygen. Therefore, the test tubes that produce alcohol are ②⑥, A is correct; the test tubes that produce CO2 and H2O are ③⑤, B is correct; test tube ① does not prove that the place where glucose is decomposed into pyruvate under oxygen conditions is the cytoplasmic matrix, C is wrong; ②④⑥ The experimental results can determine the place where yeast performs anaerobic respiration. D is correct.

Test points: This question examines the location of yeast cell respiration. It is intended to test the candidates' ability to understand the key points of the knowledge they have learned, grasp the internal connections between the knowledge, and use the knowledge they have learned to conduct experimental analysis, judgment, and reasoning. The ability to draw correct conclusions.
