BIO 100 Exam 2 (Ch. 6,7,8,9) UPDATED
ACTUAL Exam Questions and CORRECT
Answers
Photosynthesis - CORRECT ANSWER - water is oxidized (split) and carbon dioxide is
reduced using solar energy.
Combination of a reduction and an oxidation reaction is called - CORRECT ANSWER -a
redox reaction
Photosynthesis formula - CORRECT ANSWER - Carbohydrate and Oxygen (end
products)
Photosynthesis takes place in - CORRECT ANSWER - chloroplasts
Chloroplast - CORRECT ANSWER - bounded by a double membrane and contains two
main components: (1) liquid stroma (2)membranous grana made up of thylakoids
Calvin Cycle - CORRECT ANSWER - Takes place in the stroma
Calvin Cycle stages - CORRECT ANSWER -
CAM Photosynthesis - CORRECT ANSWER - plants that live in hot and dry
environments us this photosynthesis. At night stroma remain open
Raw material for photosynthesis are - CORRECT ANSWER - carbon dioxide and water
During photosynthesis, carbon dioxide is __________ and water is ___________ - CORRECT
ANSWER - reduced, oxidized
, When electrons in the reaction center of PS I are passed to a energy-accept-or molecule, they are
replaced by electron that have been given up by - CORRECT ANSWER - water
During the light reactions of photosynthesis, ATP is produced when hydrogen ions move -
CORRECT ANSWER - down a concentration gradient from the thylakoid space to the
stroma
Oxygen is generated by the - CORRECT ANSWER - light reactions
The enzyme that produces ATP from ADP+ P in the thylakoid is - CORRECT ANSWER -
ATP synthase
Energy for the Calvin Cycle is supplied by ________ from the light reactions - CORRECT
ANSWER - ATP and NADPH
Carbon dioxide fixation occurs when CO2 combines with - CORRECT ANSWER - RuBP
The output of the Calvin Cycle that is used to generate carbohydrates is - CORRECT
ANSWER - G3P
In C4 plants, CO2 fixation occurs - CORRECT ANSWER - by joining CO2 to a C3
molecule and pumping it into bundle sheath cells
A lead of a C4 plant differs from that of a C3 plant because - CORRECT ANSWER -
bundle sheath cells are protected from leaf spaces by a ring of meophyll cells
Cellular Respiration - CORRECT ANSWER - produces ATP from molecules such as
glucose.
