question_answer1) Assertion : In alcoholic fermentation, the hexose molecule is converted into glucose and fructose. Reason : Alcoholic fermentation is anaerobic respiration brought about by enzyme zymase. [AIIMS 1996]
question_answer2) Assertion : Glycolysis occurs in cytoplasm. Reason : Enzymes for glycolysis are found in cytoplasm. It is common in aerobic/anaerobic respiration [AIIMS 2002]
question_answer3) Assertion : Power house of cell is mitochondria. Reason : ATP is produced in mitochondria
question_answer4) Assertion : The inner membrane of mitochondria contains systems involving electron transport. Reason : The mitochondrial matrix contains enzymes of Kreb's cycle.
question_answer5) Assertion : Both hexokinase and glucokinase require divalent cation\[M{{g}^{++}}\]or\[M{{n}^{++}}\]. Reason : The divalent cations act as catalysts.
question_answer6) Assertion : The product of the first reaction of the Kreb's cycle is citric acid, a six carbon compound. Reason : The first reaction of the Kreb's cycle is the condensation of acetyl CoA with oxaloacetate.
question_answer7) Assertion : Cytochromes are a group of copper containing electron transferring proteins. Reason : The terminal cytochrome reacts with oxygen.
question_answer8) Assertion : Aerobic respiration consists of two steps. Reason : Glycolysis is called as common pathway.
question_answer9) Assertion : Substrate level phosphorylation is present in glycolysis. Reason : Substrate level phosphorylation causes synthesis of ATP.
question_answer10) Assertion : Under aerobic conditions, pyruvate gives rise to lactate. Reason : Under anaerobic condition, pyruvate gives rise to acetyl CoA.
question_answer11) Assertion : Terminal oxidation occurs both in aerobic and anaerobic conditions. Reason : Terminal oxidation occurs at terminal step of respiration.
question_answer12) Assertion : During the hydrolysis of typical chemical bonds, about 3000 calories per mole are liberated. Reason : ATP also yields about 3000 calories per mole after the release of any one of the two terminal phosphates.
question_answer13) Assertion : One way of indicating the ATP yield from oxidative phosphorylation is the P/O ratio. Reason : The cell stores 40% of the chemical energy.
question_answer14) Assertion : In electron transport chain, there is a gain of energy at each step. Reason : At each step of ETC, there are electron carriers.
question_answer15) Assertion : \[{{F}_{1}}\]particles are present in the inner mitochondrial membrane. Reason : An electron gradient formed on the inner mitochondrial membrane, forms ATP.
