Consider the simplified diagram of the light independent reaction on the right.

It is reasonable to conclude that carbon dioxide is represented by

C represents : the formation of a glucose molecule an oxygen molecule being given off during the light dependent stage. the absorption of a carbon dioxide molecule. ATP molecule formed during the light dependent stage. ATP molecule formed during the light independent stage. an oxygen molecule being given off during the light independent stage.

X represents
a 5 carbon molecule; a glucose molecule; ATP ADP PGAL

Y represents
ATP ADP NADPH glucose PGAL

The light independent reactions :
are not catalysed by enzymes; are endergonic; yield ATP; yield ADP and oxygen gas. yield NADP and oxygen gas.

Solution

Which one of the following reactions does not take place inside the chloroplast? a b c d

Solution

Which of the following compounds are recycled in the chloroplast? ADP and Pi as well as NADP glucose; Carbon dioxide Oxygen NADP only

Solution

ATP is formed in: mitochondria only during sunlight; chloroplasts at the thylakoid membranes during the light stage; the stroma of the chloroplasts during the dark stage; the stroma of the chloroplasts during the light stage;
Solution

Consider the high resolution image of a chloroplast shown on the right. Three parts are labelled.
ATP is formed in which structure? ATP is not formed in the chloroplast. At B during sunlight. At A during sunlight. At B during sunlight and darkness. At A during darkness.

CO₂ is used in which structure? At B during sunlight. At A during sunlight. At C during sunlight and darkness. At A during darkness.
