EXAM II
The process of ____________ captures light energy from the sun and converts it to chemical energy
stored in sugars and other organism molecules. - ANSWER-photosynthesis
write the general equation for photosynthesis from memory - ANSWER-water (6H2O) + carbon dioxide
(6CO2) + Light energy ---> glucose (C6H12O6) + oxygen (6O2)
Water enters plants through _______ and carbon dioxide enters plants through _______. - ANSWER-
their roots; pores in the leaf called stomata
Photosynthesis occurs in - ANSWER-chloroplasts
Know the structure of the chloroplast. - ANSWER-stroma, thylakoid membrane, grana, inner and outer
membrane
what is a stroma - ANSWER-a thick fluid enclosed by the inner membrane of a chloroplast; sugars are
made in the ____ by the enzymes of the Calvin cycle.
thylakoid membrane - ANSWER-one of a number of disk-shaped membranous sacs inside a chloroplast.
contain chlorophyll and the enzymes of the light reactions of photosynthesis;
Grana - ANSWER-a stack of hollow disks formed if thylakoid membrane in a chloroplast.
, are the sites where light energy is trapped by chlorophyll and converted to chemical energy during the
light reactions of photosynthesis
inner and outer membrane of chloroplast - ANSWER-the chloroplast has a double-membrane envelope.
the inner membrane encloses a compartment filled with stroma.
Chlorophyll molecules are embedded in the ________. - ANSWER-inner thylakoid membrane
the primary function of plant pigments is to - ANSWER-absorb solar energy
Leaves are green because - ANSWER-chlorophyll molecules absorb violet-blue and red light but reflect or
transmit green-yellow light
List the processes of light dependent reactions - ANSWER-chlorophyll absorbs solar energy and ejects an
electron, which is passed down an electron transport chain, and water is split, releasing O2
List the requirements for light dependent reactions - ANSWER-H2O, ADP, and NADP+
List the products of light reactions - ANSWER-O2 and energy-storing compounds ATP and NADH
List the requirements for the Calvin cycle reactions - ANSWER-ATP, NADPH, CO2, a five-carbon sugar
called RuBP, and the enzyme rubisco
_________ is fixed during the Calvin Cycle. - ANSWER-Carbon Dioxide
The product of the Calvin Cycle is _______ which can be used to make __________ - ANSWER-
glyceraldhyde-3-phosphate (G3P); glucose
How is C4 photosynthesis different from C3 (traditional) photosynthesis? - ANSWER-c3 photosynthesis
uses the three carbon molecule 3-phosphoglycerate (3-PGA) for carbon fixation -which require water; in
c4 photosynthesis a carbon shuttle system evolved in which carbon is first fixed by incorporation of
carbon dioxide into a 4 carbon molecule Oxaloacetate (OAA)
