The correct Answer is:
To analyze the given assertion and reason regarding diabetes insipidus, we will break down the statements and evaluate their accuracy step by step. ### Step 1: Understanding the Assertion The assertion states that "Diabetes insipidus is due to deficiency of insulin and is characterized by diuresis, polydipsia, hyperglycaemia, and glycosuria." - **Analysis**: - Diabetes insipidus is actually caused by a deficiency of the anti-diuretic hormone (ADH), also known as vasopressin, not insulin. - The symptoms mentioned (diuresis, polydipsia) are correct, but hyperglycemia and glycosuria are not characteristics of diabetes insipidus; they are associated with diabetes mellitus, which is related to insulin deficiency. ### Step 2: Understanding the Reason The reason states that "In diabetes insipidus, body cells cannot use glucose and liver cells cannot store glucose." - **Analysis**: - This statement is incorrect. Diabetes insipidus does not affect glucose metabolism; it primarily affects water retention in the body due to a lack of ADH. - The inability of body cells to use glucose and liver cells to store glucose is characteristic of diabetes mellitus, not diabetes insipidus. ### Step 3: Conclusion Both the assertion and the reason are incorrect regarding their definitions and characteristics. ### Final Answer - **Correct Option**: Both assertion and reason are false.

Read the assertion and reason carefully to mark the correct option out of the option given below Assertion: Diabetes insipidus is marked by excessive urination and too much thirst of water. Reason: Anti-diuretic hormone (AD) is secreted by the posterior lobe of pituitary. Assertion: FSH is also known as interstital cell stimulating hormone. Reason: It is because of the fact that FSH stimulates the interstital cells of testis.

Point out if both are true with reason being correct explanation (A), both are true but reason is not correct expalantion (B), assertion is true but reason is wrong ( C), and both are wrong (D). Assertion. After drinking, alcohol is changed into glucose in liver. Reason. Liver cells are able to form glucose from alcohol by reverse fermentation

Glucose is the prime source of emergency in our body. However, it is stored in the form of glycogen in the muscle and liver of animal and in the form of starch in plants. As a result, everytime a cell requires glucose, it must hydrolyze glycogen which is an energy consuming process. Why does the cell store glycogen instead of glucose in free form?

Read the passage given below and answer the question: Polysaccharides may be very large molecules. Starch, glycogen, cellulose, and chitin are examples of polysaccharides. Starch is the stored form of sugars in plants and is made up of amylose and amylopectin (both polymers of glucose). Amylose is soluble in water and can be hydrolyzed into glucose units breaking glycocidic bonds, by the enzymes a- amylase and B-amylase. It is straight chain polymer. Amylopectin is a branched chain polymer of several D-glucose molecules. 80% of amylopectin is present in starch. Plants are able to synthesize glucose, and the excess glucose is stored as starch in different plant parts, including roots and seeds. The starch that is consumed by animals is broken down into smaller molecules, such as glucose. The cells can then absorb the glucose. Glycogen is the storage form of glucose in humans and other vertebrates, and is made up of monomers of glucose. It is structurally quite similar to amylopectin. Glycogen is the animal equivalent of starch. It is stored in liver and skeletal muscles. Cellulose is one of the most abundant natural biopolymers. The cell walls of plants are mostly made of cellulose, which provides structural support to the cell. Wood and paper are mostly cellulosic in nature. Like amylose, cellulose is a linear polymer of glucose. Cellulose is made up of glucose monomers that are linked by bonds between particular carbon atoms in the glucose molecule.Every other glucose monomer in cellulose is flipped over and packed tightly as extended long chains. This gives cellulose its rigidity and high tensile strength-which is so important to plant cells. Cellulose passing through our digestive system is called dietary fiber.

Products of electrolysis depend on the nature of material being electrlysed and the type of electrodes being used. If the electrode is inert (e.g., platinum or gold), it does not participate in the chemical reaction and acts only as source or sink for electrons. On the other hand, if the electrode is reactive, it participates in the electrode reaction. thus, the products of electrolysis may be different for reactive and inert electrodes. Aqueous copper sulphate solution and aqueous silver nitrate solution are electrolysed by 1 ampere current for 10 minutes in separate electrolytic cells. In these question, a statement of assertion followed by a statement of reason. choose the correct answer out of the following choices. Q. Assertion (A): Copper sulphate cannot be stored in zinc vessel. Reason (R): Zinc is less reactive than copper.

Assertion (A): The negative sign in the expression E_(Zn^(2+)//Zn)=-0.76 V means Zn^(2+) cannot be oxidised to Zn. Reason (R): Zn is more reactive than hydrogen & Zn will oxidised, & H^(+) will get reduced.
