Correct Q & A
40. True or False. The ²-oxidation pathway catabolizes the fatty acid
chains of lipids.--- correct answer --- True
41. Describe the relationship between chloroplasts and chlorophyll.-
-- correct answer --- Both chloroplasts and chlorophyll are associated
with photosynthesis. Chloroplasts are the double membrane-enclosed
organelles that contain the photosynthetic pigment chlorophyll.
42. True or False--- correct answer --- Chloroplasts are specific to
algae and plants.--- correct answer --- True
43. The process of carbon fixation begins with which of the
following reac- tants? Select all that apply.
A. CO2
B. H2O
C. Glyceraldehyde-3-phosphate
D. ATP
E. NADPH--- correct answer --- CO2, H2O, ATP, NADPH
(Carbon fixation uses the ATP/NADPH produced during light reactions
to convert CO2 and H2O into useful sources of energy
(carbohydrates.))
,44. What is true pertaining to the light reactions of photosynthesis?
Select all that apply.
A. It is the second step of photosynthesis
B. Results in the formation of NADP and ADP
C. Process results in a proton concentration gradient
D. It is known as the Calvin cycle
E. It is the first step of photosynthesis
F. Results in the formation of carbohydrates
G. Process results in carbon fixation
H. Results in the formation of ATP and NADPH
I. Occurs in the membrane
J. It converts light energy into chemical energy
K. Does not depend on sunlight
L. It is known as photophosphorylation--- correct answer --- C.
Process results in a proton concen- tration gradient
E. It is the first step of photosynthesis
H. Results in the formation of ATP and NADPH
I. Occurs in the membrane
J. It converts light energy into chemical energy
L. It is known as photophosphorylation
,45. True or False--- correct answer --- The Calvin cycle must occur
in the absence of light.--- correct answer --- False
(The term 'dark reactions' (also known as the Calvin Cycle) simply
denotes the second stage in photosynthesis—dark reactions do not
actually require darkness in order to occur.)
46. How many turns (or repititions) of the Calvin Cycle are required
to generate one molecule of glucose?--- correct answer --- 6
47. Complete the following equation by placing the appropriate
numbers where indicated.
CO2 + ATP + NADPH + H20 ’C6H12O6 + ADP +
NADP+--- correct answer --- 1. 6
2. 18
3. 12
4. 12
5. 18
6. 12
6 CO2 + 18 ATP + 12 NADPH + 12 H20 --> C6H12O6 + 18 ADP + 12
NADP+
48. Match the following reactions to its corresponding enzyme---
correct answer ---
1. AB+H2O’AOH+BH
2. AB’BA
, 3. A+B’AB
4. AB’A+B--- correct answer --- 1. Hydrolases
2. Isomerases
3. Ligases
4. Lyases
49. True or False--- correct answer --- A nanometer (10-9) is longer
than a micrometer (10-6).--- correct answer --- False (A nanometer is
1,000 times smaller than a micrometer.)
50. Resolution and contrast are two critical factors that influence
your ability to see an object. Explain each.--- correct answer ---
Resolution refers to the distance between two objects at which the
objects still can be seen as separate. Poor or low resolution means two
(or more) objects may appear as one.
Contrast is the difference in light absorbance between two objects.
Poor contrast gives a high background and makes the visualization of
multiple objects difficult. For instance, trying to identify 2 dark
colored objects at night (low light = low contrast) versus the same 2
objects in the middle of a sunny afternoon (bright light against 2 dark
objects = high contrast).
51. Assuming a fixed ocular, identify the part of the microscope you
would adjust to enhance the magnification of a sample.
A. Eyepiece
B. Condenser
