Who discovered the $C_3$ cycle of photosynthesis?

Explain: Where are $ATP$ and $NADPH$ used?

The process in photosynthesis that is also called the dark reaction is so named because:

Radioactive $C^{14}$ is incorporated into $CO_2$ and released into the atmosphere. This $CO_2$ is taken up by $RuBP$ in a $C_3$ plant. In which compound is the radioactive $C^{14}$ first detected?

Which of the following represents the Calvin cycle?

Suspension of isolated thylakoids in a culture medium containing $CO_2$ and $H_2O$ does not produce hexose due to the absence of which of the following?
