Other questions in this quiz

2. ..................... reactions are used to reduce Glycerate 3 phosphate to triose phosphate in the calvin cycle.

  • ATP to ADP + Pi & NADP + H to NADPH
  • me + banana
  • ATP to ADP + Pi & NADPH to NADP + H
  • ADP + Pi to ATP & NADPH to NADP + H

3. In the light-indepedent reaction (Calvin cycle) Ribulose biphospate combines with CO2, aided by enzyme action. What is the product of this?

  • Glycerate 3 phospate
  • Triose phospate
  • ADP and Pi
  • Phosporylated glucose

4. In the calvin cycle, some of the Triose Phospate created is converted into glucose. What is NOT a possible use of the glucose produced?

  • Conversion into starch for storage
  • Nitrification in roots
  • Use in respiration
  • Making proteins

5. What is the function of light in the light-depedent reaction?

  • To make ATP, photolysis of water, To enable the chlorophyll to take up an electron
  • To reduce CO2, to make ATP, to excite an electron in chlorophyll
  • To make ATP, photolysis of water, to excite an electron in chlorophyll
  • photolysis of water, to reduce glycerate-3-phospate, to make ATP
