BIOLOGY CHAPTER 8 PHOTOSYNTHESIS
QUESTIONS AND ANSWERS ALL
VALIDATED AND VERIFIED.
Reaction formulas for Photosynthesis: - CorreCt Answers -6CO2+6H2O----
>C6H1206+6O2 (symbols)
Carbon Dioxide+Water---->Sugars and Oxygen (words) - CorreCt Answers
-(Other) reaction formula for Photosynthesis
Light-Dependent Reactions (Light Cycle) - CorreCt Answers -happens
during the day for most plants. Produces ATP and NADPH+ for later and
Oxygen is a byproduct. Takes place on the thylakoid membrane. Water is
required.
Light-Dependent Reactions (Dark Cycle/Calvin Cycle) - CorreCt Answers -
uses ATP, NADPH+, and carbon dioxide from the atmosphere to make
sugars for the plant. Takes place in the stroma.
(8.3) The LDRS (light-dependent reactions) use energy from the sunlight to
produce... - CorreCt Answers -oxygen and convert ADP and NADP+ into
ATP and NADPH+
Photosystems - CorreCt Answers -clusters of chlorophyll and proteins
located on the thylakoid membrane.
, Role of photosystems (in general) - CorreCt Answers -to absorb sunlight
(both contain chlorophyll)
Role of Photosystem II - CorreCt Answers -absorb sunlight and break down
Water molecules into hydrogen and oxygen (releases oxygen into air).
Sends electrons from sunlight through an electron transport chain (ETC)
Electron Transport Chain (ETC) - CorreCt Answers -a series of electron
carrier proteins.
Role of ETC - CorreCt Answers -TO shuttle high-energy electrons during
ATP generating reactions and pump H+ ions from the stroma into the
thylakoid space. Send electrons from Photosystem II to Photosystem I.
Role of Photosystem I - CorreCt Answers -takes electrons from ETC and
releases them into the stroma. There, the H+ ions turn NADP+ into
NADPH+.
Some H+ Ions are... - CorreCt Answers -pumped from the stroma into
thylakoid space through electron carriers
ATP Synthase - CorreCt Answers -protein that spans the thylakoid
membrane and and allows H+ ions to pass through and forces ATP
synthase to rotate.
Role of ATP Synthase - CorreCt Answers -through the spinning due to the
traveling H+ ions, it binds ATP and a phosphate group to make ATP
