Respiration is an energy releasing and enzymatically controlled catabolic process which involves a step-wise oxidative breakdown of organic substances inside living cells. In this, statement about respiration explain the meaning of Step-wise oxidative breakdown.

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 ofperforming anaerobic respiration, when the oxygen levels are depleted .Even body cells like erythrocytes and mscle cells perform anaerobic respiration. How does anaerobic respiration occur in yeast?

Read the following statements and find out the incorrect statement. A. Ultimately all the food that is respired for life processes comes from photosynthesis. B. The energy released by oxidation in respiration is directly used for the life processes. C The carbon skeleton produced during respiration is used as precursors for biosynthesis of other molecules in cell. D. Plants, unlike animals, have no specialised organs for gaseous exchange but they have stomata and lenticels for this purpose. E. During oxidation within a cell, all the energy contained in, respiratory substrates is released free into the cell in a single step, which is trapped as chemical energy in the form of ATP.

Paragraph based Questions : Read the paragraph and answer the questions given below : Remediation is the process of removing dangerous or poisonous substances from the environment, or limiting the effect that they have on it. When any biological organism is used for remediation, it is called bioremediation. When plant species are used for the purpose of remediation, it is called phytoremediation. When any microbes are used then it is named as microbial remediation. The methods of such remediation have helped to clean the environment from toxic effluents, especially sewage and crude oi]. Dr. Anand Chakraborty, a scientist of Indian origin, has worked on Pseudomonas aeruginosa which have reduced the crude oil films into carbon dioxide and water. What is the meaning of remediation?

Read the following paragraph and answer the questions: If heat is exchanged between a hot and cold object, the temperature of the cold object goes on increasing due to gain of energy and the temperature of the hot object goes on decreasing gue to loss of energy. The change in temperature continues till the temperatures of both the objects attain the same value. In this process, the cold object gains heat energy and the hot object loses haet energy. If the system of both the objects is isolated from the environment by keeping it inside a heat resistance box (meaning that the energy exchange takes place between the two objects only ), then no energy can flow from inside the box or come into the box. Which property of the substance is measured using this principle ?
