The correct Answer is:
To solve the question, we need to match each statement with the correct answer. Let's break it down step by step: ### Step 1: Analyze the first statement **(a) Net ATP produced in glycolysis** - Glycolysis occurs in the cytoplasm and involves converting glucose into pyruvate. - In the preparatory phase, 2 ATP are consumed, and in the payoff phase, 4 ATP are produced. - Therefore, the net ATP produced is 4 - 2 = 2 ATP. - Additionally, 2 NADH molecules are produced, which can yield more ATP in the electron transport chain. - Each NADH can produce approximately 2.5 ATP, leading to a total of 2 NADH x 2.5 ATP = 5 ATP. - Thus, the total ATP from glycolysis = 2 (net) + 5 (from NADH) = 7 ATP. ### Step 2: Analyze the second statement **(b) Positive Benedict's test** - The Benedict's test is used to detect reducing sugars, which have a free aldehyde or ketone group. - Glucose is a common reducing sugar that gives a positive result in the Benedict's test. - Therefore, the correct match is glucose. ### Step 3: Analyze the third statement **(c) Genes unable to express in presence of their alleles** - This refers to alleles that do not manifest their traits when a dominant allele is present. - Such alleles are known as recessive alleles. - Hence, the correct match is recessive. ### Step 4: Analyze the fourth statement **(d) A character controlled by many genes** - Characters that are influenced by multiple genes are referred to as polygenic traits. - Examples include skin color, height, and eye color. - Therefore, the correct match is polygenic. ### Final Matching Now we can summarize the matches: - (a) Net ATP produced in glycolysis = 7 ATP - (b) Positive Benedict's test = Glucose - (c) Genes unable to express in presence of their alleles = Recessive - (d) A character controlled by many genes = Polygenic ### Conclusion The correct matches are: - A: 7 ATP - B: Glucose - C: Recessive - D: Polygenic The correct option based on these matches is **option number 2**: 7 ATP, Glucose, Recessive, Polygenic. ---
