Fig. 1.1 shows an electronmicrograph of a chloroplast.
On Fig. 1.1, use label lines and letters to label one place where:
L – the light-dependent stage takes place
R – the enzyme rubisco is found.
Chloroplasts can move within palisade cells.
Suggest two advantages of chloroplast movement within palisade cells.
Complete the following paragraph by naming the most suitable compounds to fill in the gaps.
Rubisco is involved in the fixation of ______ by RuBP (ribulose bisphosphate) in the Calvin cycle. The resulting six carbon compound immediately splits to give two molecules of glycerate-3-phosphate (GP). GP is converted to triose phosphate (TP) using ______ and ______ produced in the light-dependent stage. Some of the TP produced is used to regenerate ribulose bisphosphate so that the Calvin cycle can continue. The remaining TP may be used to synthesise other compounds including ______ which can directly enter the Krebs cycle.
