AP Biology Questions with CORRECT Answers

Question:
Describe the role of the carrier molecule NADP in photosynthesis.
Answer:
NADP is an important molecule used in cellular respiration (or making energy). When a
cell breaks down glucose it converts 2 NADP molecules into 2 NADPH molecules,
basically a NADP molecule with an extra hydrogen attached.


Question:
Explain the role of chlorophyll molecules in photosynthesis.
Answer:
It turns light into sugars which they use as fuel.


Question:
Summarize the events of light dependent reactions and identify where they occur.
Answer:
Photosynthesis occurs in 2 partsThe light reactions and the Calvin Cycle. The light cycle
is dependent on light.


Question:
When light strikes the chlorophyll then a electron comes out from the outermost orbit
which activates the chlorophyll.The activated chlorophyll breaks the water into H+ and
OHions.this process is called photolysis/Hill's Reaction.
Answer:
Describe how ATP is produced as a result of light striking chlorophyll molecules during
the light dependent phase.


Question:
the end products is glucose,reduced NADP,water,oxygen,a.t.p.out of
photophosphyrylation. dark phase of photosynthesis occurs in the stroma. non-cyclic
phosphorylation
Answer:
Non Cyclic photophosphorylation operates in a zig-zag manner and involves two
chemically and physically distinct photosystem (PS I and II), linked together by electron
transport chain.
