In eukaryotes, all the reactions of photosynthesis occur in various membranes and compartments of the chloroplast. a. True
b. False

The correct answer is - a. true.

Explanation:

The chloroplast is surrounded by inner and outer membranes. These membranes help in separating the inner compartments and structures from the cytosol Inside the chloroplast. These various membranes and compartments play various roles during photosynthesis.

For instance;

a) stroma- the Calvin cycle takes place in the stroma

b) thylakoid membrane - the light reactions takes place here

c) envelope membranes- the inner and outer membranes of the chloroplast

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.
