The hourly energy requirements of an astronaut can be satisfied by the energy released when 34 grams of sucrose are "burnt" in his body. How many grams of oxygen would be needed to be carried in space capsule to meet his requirement for one day?

Two different kinds of food A and B are being considered to form a weekly diet . The minimum weekly requirements for fats , carbohydrates and protein are 18, 24 and 16 units respectively . One kg of food A has 4 , 16 , and 8 units respectively of these ingredients and one kg of food B has 12 ,4 and 6 units respectively The price of food A is Rs 6 per kg and that of food B is Rs 5 per kg. How many kg of each type of food should he buy per week to minimize the cost and meet his requirements . Formulate this LPP

Cellular respiration is the oxidation of foodstuffs for the production of energy. During aerobic respiration, complete oxidation of glucose takes place.Contradictor to this, glucose is incompletely oxidized durin anaerobic respiration . Many microbesare capacble of surviving anaerobically in environments that lack oxygen. Anaerobic respiration occurs via two steps,namely glycolysis and fermentation. The pyruvic acid formed during glycolysis is converted to organic acids or alcohols during anaerobic process. higher animals and plants, or seeds submerged in soil under water are capable of performing anaerobic respiration, when the oxygen levels are depleted .Even body cells like erythrocytes and mscle cells perform anaerobic respiration. Considering that only glycolysis is generating energy currency , how many ATP would be formed during anaerobic respiration?
