Q

How is energy transferred without moving electrons?

A

Electron acts as energy store in each antenna molecule and the reaction centre is using its physical quantum state to define it

Q

How much ATP and NADPH is
required to synthesise 1 molecule of
Glyceraldehyde-3-phosphate in the
Calvin-Benson cycle?

A

6 NADPH and 9 ATP

17
Q 
The light dependent reactions of
photosynthesis generate equal
amounts of ATP and NADPH, but
carbon assimilation reactions require 9
ATP molecules and 6 NADPH
molecules. How does the chloroplast
generate an excess of ATP to
compensate?
A

Cyclic electron flow through photosystem I
