The light reactions of photosynthesis supply the calvin cycle with

The light reactions of photosynthesis supply the calvin cycle with ATP and NADPH.

Explanation:

In the light reaction the energy from photons present in the sunlight is used to split water into oxygen, hydrogen ions, and electron. These electrons moves through the electron transport chain and produce chemical energy in the form of ATP and  NADPH.

This ATP and NADPH is supplied to the Calvin cycle and the energy released by these molecules is used to convert carbon dioxide into glucose molecules with the help of the enzyme RuBisCo. As Calvin cycle does not require light, therefore, it is a light-independent reaction.

Therefore the light reactions of photosynthesis supply the Calvin cycle with ATP and NADPH.

you are certainly talking about this picture:

a: is the label of the white square, it is showing the  replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication 

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes  the dna with the dna template and increases  the processivity of the enzyme. ==>   stops polymerase from falling off the  template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built  in the opposite sense of the helicase, so dna will be built in fragments ==> built  fragments from 5' to 3 joins

and finally f: is the enzyme that builds  the new dna strand (dna polymerase) ==>   adds nucleotides to make a new dna helix.
