A limiting factor in photosynthesis is one which

The light indpendent stage of photosynthesis takes place in

Which of the following is/are required for the light-independent stage of photosynthesis?

In photosynthesis, the hydrogen ions from the photolysis of water are involved in the

Whilst the light independent stage does not directly use light energy, it will only continue for as long as the products of the light dependent stage are available. These products are

How does most carbon dioxide enter the air spaces in the spongy mesophyll of a leaf

The substance required in chloroplasts as a carbon dioxide acceptor compound is known as:

For the light independent stage of photosynthesis, which one of the following is incorrect?

Why does the concentration ratio of O2:CO2 in the leaf limit the rate of carbon fixation during the Calvin cycle?

Carbon dioxide labelled with 14C has been used to identify the intermediate compounds in the Calvin cycle, the light independent stage in photosynthesis. Which compound from the list would be the first to contain the 14C?

In the Calvin cycle, at which stage is most of the reduced NADP oxidised?

If light intensity is uniformly high, under which of the following conditions is carbon dioxide most likely to be the main limiting factor upon the rate of photosynthesis?

In the conversion of RuBP to GP

In which stage of the Calvin cycle is reduced NADP and ATP used?

How many molecules of ATP are converted to ADP and inorganic phosphate when one molecule of CO2 is fixed during the Calvin cycle?

The light compensation point is when

What proportion of TP molecules produced during the fixation of 6 molecules of CO2 are used to regenerate RUBP?

When light intensity decreases, what happens to concentrations of RUBP, TP and GP?

Stomata close in conditions of water stress. Why would this result in reduced CO2 fixation in C3 plants?

Which of the following describes conditions in a photosynthesising cell, exposed to high light intensity and low carbon dioxide concentration?

The Calvin cycle in photosynthesis is limited by

A mutation occurs in the chloroplasts of a spinach plant, causing the thylakoid membranes to become permeable to H+ ions. How might this affect the production of TP and the regeneration of RUBP?

During the light independent stage of photosynthesis, 1 molecule of glucose is formed from

The chloroplast is adapted to carrying out the light independent stage of photosynthesis as
