Multiple choice

Consider the following statements :

  1. The Penthose Phosphate Pathway supplies Erythrose-4-Phosphate which is the starting material in the synthesis of lignin.
  2. The Pentose Phosphate Pathway also occurs in plastids.
  3. NADPH is generated by the Pentose Phosphate Pathway. Which of the statements given above are correct?

  1. 1 and 2 only

  2. 2 and only

  3. 1 and 3 only

  4. 1,2 and 3
