  1. Six

  2. Seven

  3. Five

  4. Four
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The brush borders of the intestinal lining are the site of terminal carbohydrate digestions. The microvilli that constitute the brush border have enzymes for this final part of digestion anchored into their apical plasma membrane as integral membrane proteins. Maltase, lactase, erepsin, nucleosidase are the brush border enzymes.

Citrate undergoes dehydration to form unstable compound

  1. iso-citrate

  2. succinate

  3. cis-aconitate

  4. aconitate
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In step two, an enzyme called aconitase converts citrate into isocitrate. Next, an isocitrate dehydrogenase enzyme oxidizes isocitrate, a six-carbon molecule, to a five-carbon α-ketoglutarate. The carbon that was lost is released as carbon dioxide and one NADH is also formed.

So, the correct option is, 'Isocitrate'.
