(True)

8) Acetyl co A is an ideal substrate for gluconeogenesis.              

(False)

9) Insulin promotes lipolysis by stimulating hormone sensitive lipase.

(False)

10) Oral glucose tolerance test is a confirmatory test in suspected cases of diabetes mellitus.                                                                                   

(True)

11) Aconitase enzyme catalyzes the condensation of Acetyl co A and Oxalo acetate.

(False)

12) Enolase is inhibited by Arsenate.                                          

(False)

13) Inherited Aldolase A and pyruvate kinase deficiencies in erythrocytes cause hemolytic anemia.                                                                   

(True)

14) Muscle glycogen functions to store and export glucose to maintain blood glucose between meals.                                                                        

(False)

15) Glucose 6-phosphatase hydrolyzes glucose 6-phosphate in muscles, yielding glucose that is exported, leading to an increase in the blood glucose concentration.                                                                                                     

(False)

(True)        

18) Epinephrine and nor epinephrine stimulate the release of insulin.

( False )

19) Glucose 6-phosphate dehydrogenase is an NAD+dependent enzyme.

( False)

20) Ribose can not be synthesized in all tissues.                          

( False)

21) In the liver, fructose increases triacylglycerol synthesis and VLDL secretion, leading to hypertriacylglycerolemia.                                                                                                                                                           

(   True )

22) Microalbuminuria is a measure of an early and reversible nephropathy.

(   True     )

23) A low blood glucose level is more harmful than hyperglycemia.    
( True)

24) Hypoglycemia is not a diagnosis but is a biochemical sign associated with a group of diverse diseases.                                                                      

( True)

25) A fall in pH stimulates phosphofructo kinase activity.            

( False )

26) GLUT5, present in the small intestine, functions primarily as a fructose transporter.

( True  )

27) Glycolysis is diminished and gluconeogenesis is accelerated in the fed state.

( False)

28) The formation of acetyl CoA from carbohydrates is less direct than from fat.

(True )

29) The rate of TCA cycle is reduced when the cell has a high level of ATP.

(True )

30) Two high-energy phosphate bonds are consumed in a reaction, which is catalyzed by pyruvate carboxylase.                                                                                                                                                                    

( False )

6 Responses to Solution To Questions From Carbohydrate Metabolism- State True or False

  • So my dear students, check your answers,i hope you all must have done well.
    Be bold to write me,
    Good luck for next time !

    Checked the other one. Glad to see I did well. Didn't get enough time to go through this one too though! Mam, could I suggest you giving us a little bit more time when you post the next brain storm or quiz or question list? :) So that at least a minimum number of students get time to go through it and answer them.

    Otherwise, thank YOU Mam for the amazing work you're doing. Some of the questions really force us to think and read over. Your dedication is overwhelming and makes us want to work harder each time. Plus, you keep us on our toes constantly.

  • Hi Sneha,
    Thanks for the feed back. Surely i shall make a point to make all of you comfortable for answering my questions. This whole effort is for you all only, and your verdict means a lot to me.
    Well from now onwards, i shall post the questions on saturday and their answers on monday. Will that be o.k. ? I ll take a break on sunday.

  • Sneha Desai says:

    Yes Mam, I think it'll give a lot more students the opportunity to answer the questions, or at least, I hope so. Then they'll have Saturday evening as well as the whole of Sunday, which is better I guess. :) Thanks for considering the suggestion. 😀

    Yeah, you sure need a break anyway! :) Thanks Mam.

  • That's a nice good suggestion by Sneha. But also, it is good that the questions and their answers are published in two different posts. This allows us to take the test even after the the answers are released.

  • Thanks Kavish and Sneha for all the good work and suggestions. Ofcourse i shall follow all your suggestions. Keep studying and discussing, sounds very pleasant.
