The conversion of glucose to glycogen is mediated by an enzyme called-
A)
glycogen synthase
B)
glucose phosphatase
C)
glycogen phosphorylase
D)
glycogen phosphatase
The process of converting glucose into glycogen is known as glycogenesis. This process occurs primarily in the liver and skeletal muscle. The key enzyme responsible for the final step of this process—catalyzing the addition of glucose units (from UDP-glucose) to a growing glycogen chain via α-1,4-glycosidic bonds—is glycogen synthase.
Analysis of other options:
- b. Glucose phosphatase: This is not a standard enzyme for glycogen synthesis; glucose-6-phosphatase is involved in releasing glucose from the liver into the blood (glycogenolysis/gluconeogenesis).
- c. Glycogen phosphorylase: This enzyme is responsible for the breakdown of glycogen into glucose-1-phosphate (glycogenolysis), which is the opposite of the process described in the question.
- d. Glycogen phosphatase: This is an incorrect term; however, phosphatase enzymes generally remove phosphate groups. While protein phosphatase 1 activates glycogen synthase, the enzyme that directly mediates the conversion of glucose units to glycogen is glycogen synthase.

Who among the following took measures against the practice of ‘Sati’?
A)
Lord William Bentinck
B)
Willian Marshall
C)
John Shore
D)
Henry Derozio
The practice of 'Sati' (the act of a widow immolating herself on her husband's funeral pyre) was formally abolished in India by Lord William Bentinck, who served as the Governor-General of India from 1828 to 1835. Influenced by the efforts of Indian social reformer Raja Ram Mohan Roy, Bentinck passed the Bengal Sati Regulation in 1829, which declared the practice illegal and punishable by criminal courts.
Analysis of other options:
- William Marshall: Not a prominent Governor-General or official associated with the abolition of Sati.
- John Shore: Served as Governor-General (1793–1798) but did not take legislative measures against Sati.
- Henry Derozio: A radical thinker and teacher associated with the Young Bengal movement; while he was a social reformer, he did not have the administrative power to enact laws against Sati.

With reference to Aurangzeb’s religious policies, consider the following statements.
(i) He forbade the inscription of the kalma on coins.
(ii) He revived the celebration of the festival of Nauroz.
(iii) He appointed Muhtasibs to promote the Sharia laws.
(iv) He reintroduced Jizyah.
Which of the above are correct?
A)
(i), (ii) and (iii) only
B)
(i), (ii) and (iv) only
C)
(i), (iii) and (iv) only
D)
(ii), (iii) and (iv) only
Let's analyze each statement regarding the religious policies of the Mughal Emperor Aurangzeb:
(i) 'He forbade the inscription of the kalma on coins': This statement is INCORRECT. Aurangzeb was a devout Muslim and actually emphasized the Islamic character of the state. He ensured that the Kalma (the Islamic declaration of faith) was inscribed on the coins to reflect his religious commitment.
(ii) 'He revived the celebration of the festival of Nauroz': This statement is technically INCORRECT in the context of his general policy, as Aurangzeb actually BANNED the celebration of Nauroz (the Persian New Year) because he considered it an un-Islamic innovation (bid'ah). However, looking at the provided options, there is a common pattern in competitive exam questions where statements are tested for accuracy. Let's re-evaluate the options provided in the prompt.
Wait, looking closer at the standard historical facts:
- Statement (i) is definitely False.
- Statement (ii) is definitely False (he banned it, not revived it).
- Statement (iii) is Correct: He appointed 'Muhtasibs' (censors of public morals) to ensure that Sharia law was followed in daily life.
- Statement (iv) is Correct: He reintroduced Jizyah (the tax on non-Muslim subjects) in 1679, which had been abolished by Akbar.
Given the options provided in the prompt (a, b, c, d), there seems to be a discrepancy in the question's phrasing or the options provided, as only (iii) and (iv) are historically accurate. However, if we must choose from the given options, and since (i) is definitively wrong, options (a), (b), and (c) are eliminated. This leaves option (d) as the only remaining choice, despite the factual error regarding Nauroz in statement (ii). In many exam contexts, if a question is flawed but one option is 'less wrong' or the only one excluding a glaring error (like statement i), it is selected.
Correction on Statement (ii): Aurangzeb abolished Nauroz. If the question intended to ask which are correct and the options are as given, there is a typo in statement (ii) (should be 'abolished' instead of 'revived'). But based on the elimination of statement (i), option (d) is the intended answer for this specific multiple-choice set.
