In bundle sheath cells of C4 plants, the C4 acids are broken down to release

  • (a) CO2 and a 5-carbon molecule Your answer
  • (b) CO2 and a 3-carbon molecule Correct
  • (c) O2 and a 3-carbon molecule Your answer
  • (d) water and RuBP Your answer
Your answer: Correct answer: (b)

Explanation

Why (b) is correct

In the bundle sheath, the C4 acids are broken down (decarboxylated) to release CO2 and a 3-carbon molecule.

Why the other options are wrong

  • (a) · your answer The other product is a 3-carbon, not a 5-carbon molecule.
  • (c) · your answer O2 is not released in decarboxylation.
  • (d) · your answer Water and RuBP are not the products.
NCERT point: The CO2 released then enters the Calvin cycle.
