Question
Characteristics of succinate dehydrogenase include all, EXCEPT a. also known as succinate-Coenyzme Q reductase. b. has covalently bonded FAD. c. is a membrane-bound enzyme. d. removes hydrogens from C-O bonds. e. transfers electrons to FAD. How many NADH molecules are produced in the TCA cycle per acetyl-group that enters the cycle as acetyl-CoA? a. 1 b. 2 c. 3 d. 4 e. 5 This structure represents the basic disaccharide of which polymer? a. maltose b. sucrose c. cellulose d. lactose e. none of the above The hemiacetal carbon in the structure shown in # 25 is a. the carbon labeled B b. the carbon labeled C c. the end carbon on the left side of the structure d. carbon # 6 on the left sugar e. Carbon # 6 on the right sugar.Explanation / Answer
Q.24) 3NADH molecules are produced for each acetyl co A which enters TCA
Hence answer is 'c'-3
Q.25) maltose should have two ethy alcohol groups, sucrose should have three ethyl alcohol groups , cellulose is a polysaccaride and lactose should have eight hydroxyl groups .
The answer is ' d' non of the above.
Q.26)carbonyl group in aldehydes and ketons may react with one molecule of alcohol to form Hemiacetal.
The answer is ' b' , where the carbon labelled c has been attacked by an alcohol group giving rise to hemiacetal.
