UA BSC 108 EXAM 2 EXAMPREP TESTED
QUESTIONS AND DETAILED SOLUTIONS
◉ How does carbon dioxide enter plants?
Answer: Through pores in the leaf called stomata
◉ TRUE OR FALSE: Photosynthesis occurs in chloroplasts
Answer: TRUE
◉ What is the structure of a chloroplast?
Answer: Stroma
Thylakoid membrane
Grana
Inner membrane
Outer membrane
◉ What is embedded in the inner thylakoid membrane?
Answer: Chlorophyll molecules
◉ What is the primary function of plant pigments?
Answer: To absorb solar energy
,◉ Why are leaves green?
Answer: Chlorophyll molecules absorb violent-blue and red light
They reflect or transmit green-yellow light
◉ What are the processes of light dependent reactions?
Answer: Chlorophyll absorbs solar energy and ejects an electron
This is passed down an electron transport chain
Water is split, releasing O2
◉ What are the requirements for light dependent reactions?
Answer: H2O
ADP
NADP+
◉ What are the products of light reactions?
Answer: O2
Energy-storing compounds ATP and NADH
◉ What are the requirements for the Calvin cycle reactions?
Answer: ATP
NADPH
, CO2
Five-carbon sugar called RuBP
Enzyme Rubisco
◉ TRUE OR FALSE: Carbon dioxide is fixed during the Calvin cycle
Answer: TRUE
◉ What is the product of the Calvin cycle? What can this be used to
make?
Answer: Glyceraldehyde-3-phosphate (G3P)
Glucose
◉ What is C4 photosynthesis an adaptation for?
Answer: Hot and dry weather
◉ What are two examples of a C4 plant?
Answer: Sugar cane
Corn
◉ What is photosynthesis?
Answer: The process that stores energy in the form of glucose
