Which product[s] of the light dependent stage of photosynthesis are used in the light independent stage of photosynthesis?

In the primary reaction center of photosystem 1 [PS1] the chlorophyll a molecule has a maximum absorption of

Reduction is

When a chlorophyll molecule absorbs light energy what is emitted from the molecule?

When a chlorophyll molecule absorbs light energy, the molecule becomes ionised. What is this process called?

During non-cyclic photophosphorylation, electrons are emitted from primary chlorophyll pigments in reaction centres situated in

Non cyclic photophosphorylation is known as the

The final electron acceptor in cyclic photophosphorylation is

When photons of light are absorbed by P680, the deficit of electrons in P680 is replenished by

Which enzyme, situated on the outer thylakoid membrane, catalyses the reduction of NADP?

What form a transfer chain within the thylakoid membranes?

During photophosphorylation, ATP is produced by

How do hydrogen ions enter the thylakoid space from the stroma?

What process contributes to the lowering of the pH inside the thylakoid space?

Why do hydrogen ions move back from the thylakoid space into the stroma?

Why do hydrogen ions only move from the thylakoid space into the stroma through ATP synthase channels?

As hydrogen ions pass through ATP synthase channels, energy is transferred to enable

What is the final electon acceptor in non cyclic photophosphorylation?

What happens to the hydrogen ions produced during the splitting of water?

A student investigated the gas exchange of canadian pondweed at a temperature of 16oC. In the light, the pondweed released oxygen at a rate of 200cm3 hr-1. In the dark the pondweed absorbed oxygen at a rate of 60cm3 h-1. What is the best estimate of the gross rate of photosynthesis by the pondweed at 16oC in cm3 hr-1?
