The five carbon compound that is found in the Calvin Cycle

• Oxaloacetate

• Citrate

• Acetylcoenzyme

• Rubiscos

• RuBP

What is the correct sequence in the Calvin cycle

• RuBP + CO2 ->

  Glycerate 3 Phosphate -> 2 Triose Phosphate

• RuBP ->

  Triose Phosphate

  -> Glycerate 3 phosphate

• Triose Phosphate

  -> Glycerate 3 Phosphate

  -> RuBP +CO2

• CO2 -> Glycerate 3 Phosphate

  -> Triose Phosphate

  -> RuBP

The light dependent reaction involves ionisation. Which two molecules are ionised using wavelengths of light?

• Chlorophyll and oxygen

• Oxygen and water

• Chlorophyll and water

• NADP and ATP

• Chlorophyll and NADP

In the light dependent reaction, which statements are correct?

• Water is split by photolysis to produce protons, electrons and oxygen

• Electrons pass through proteins in the thylakoid membranes in a series of redox reactions

• NADP becomes reduced by combining with hydrogen and electrons

• ATP is used to phosphorylate chlorophyll

• Carbon dioxide is fixed using the enzyme Rubisco

Higher temperatures result in faster rates of the light independent reaction of photosynthesis. Which statements are correct to explain why?

• Greater successful collisions between Rubiscos active site and substrates

• More Enzyme Substrate complexes form

• Rubiscos active site is saturated so no more ES-complexes form

• The bonds in Rubiscos tertiary structure become weaker and so the enzyme starts to denature.
