GENERAL BIOLOGY (BSC MISC) COMPLETE EXAM (CHAPTER 5-9 ) ALL CORRECT
Chapter 05: Photosynthesis
1. Where in the eukaryotic cells does photosynthesis occur?
a. Golgi body
b. mitochondrion
c. chloroplast
2. Light is required for the light dependent reactions because------------
a. It is the source for electrons
b. It splits the water molecule
c. It energizes electrons in the reaction center
d. It splits ATP molecules which generates the energy necessary to power the light independent
reactions
e. None
3. The primary form of sugar transported from the site of photosynthesis to the rest of the plant
is
a. Glyceraldehyde 3-phosphate
b. Glucose
c. Fructose
d. Ribulose 1, 5-bisphosphate
e. Sucrose
4. Rubisco-------------
a. Catalyzes the carboxylation of CO2 to ribulose 1,5-bisphosphate
b. Initiates photorespiration when the CO2/O2 ratio is low
c. Catalyzes the reduction of two molecules of PGAL to form glucose
GENERAL BIOLOGY (BSC MISC) COMPLETE EXAM ( CHAPTER 5-9 ) ALL CORRECT
, d. All the above
e. A and b but not c
5. Which of the following statements about photosynthesis is true?-------------
a. The light-dependent reactions can occur only in the light, the light-independent reactions only in
the dark
b. Photorespiration is more efficient at producing glucose than is photosynthesis
c. The light-dependent reactions produce the energy-rich compounds that are used to run the
light-independent reactions
d. All the above are true
6. Which of the following statements accurately describes the relationship between photosynthesis and
cellular respiration?---------
a. Photosynthesis occurs only in autotrophs; cellular respiration occurs only in heterotrophs
b. Photosynthesis uses solar energy to convert inorganics to energy-rich organics; respiration
breaks down energy-rich organics to synthesize ATP
c. Photosynthesis involves the oxidation of glucose; respiration involves the reduction of CO2
d. The primary function of photosynthesis is to use solar energy to synthesize ATP; the primary
function of cellular respiration is to break down ATP and release energy
e. Photosynthesis and cellular respiration occur in separate, specialized organelles; the two processes
cannot occur in the same cell at the same time
