1.

The light-dependent reactions take place in the

stroma
cytoplasm
outer membrane
thylakoid membranes
2.

Photolysis is

the splitting of water using light energy
the fixing of carbon dioxide
the making of glucose
the breakdown of ATP
3.

In the light-independent reactions, carbon dioxide is fixed by combining with

GALP
GP
NADP
RuBP, catalysed by RUBISCO
4.

GP is reduced to GALP using

ATP and reduced NADP
oxygen
carbon dioxide
light directly
5.

Most GALP is used to

regenerate RuBP
make starch
make lipids
make amino acids
6.

Reduced NADP is formed

in the Calvin cycle
when electrons and H⁺ are accepted by NADP at the end of non-cyclic photophosphorylation
in cyclic photophosphorylation only
in the stroma from RuBP
7.

Chloroplasts have a large membrane surface area because

they have cristae
thylakoids are stacked into grana
they have a double nucleus
they contain starch
8.

GALP can be used to synthesise

only glucose
only starch
only cellulose
hexoses, amino acids, lipids and nucleic acids
9.

Phosphorylation of ADP in the chloroplast is driven by

light directly
the Calvin cycle
a proton gradient across the thylakoid membrane
diffusion of oxygen
10.

Chlorophyll appears green because it

absorbs green light
emits green light
absorbs all light
reflects green light and absorbs mainly red and blue light
