  4. placenta

Show answer
Correct Option: C
Explanation:

Archenteron is the primary cavity which is formed at the initial stage of gastrulation. This cavity begins at the dorsal lip of blastopore which is at the one side of the dividing zygote and then this cavity moves through the zygote to the other side which gives rise to the anus. 

So the correct option is 'lumen of digestive tract

  1. Six

  2. Seven

  3. Five

  4. Four

Show answer
Correct Option: D
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.

So, the correct option is 'four'.

  1. iso-citrate

  2. succinate

  3. cis-aconitate

  4. aconitate

Show answer
Correct Option: A
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'.
