The natural hydrogen acceptor in chloroplasts that DCPIP replaces in the Hill reaction is NADP. Reduced NADP is then required in the light independent stage of photosynthesis. State the role of reduced NADP in the light independent stage.
Predict and explain how the concentration of RuBP in the chloroplasts would change if DCPIP is reduced instead of NADP.
Explain why tube A is used as the colour standard and why the beaker containing the chloroplast-DCPIP mixture is wrapped in foil.
Fill in Table 2.1 by calculating the rate of the light dependent stage of photosynthesis for the orange wavelength, using the formula: $\text{rate} = \frac{1000}{t}$ where $t$ = time in seconds.
Using Table 2.1 as evidence, describe and explain how light wavelength affects the rate of the light dependent stage of photosynthesis.
