BIOL 1450 Lab Practical #2 Exam Questions
With Correct Answers
What |treatments/ |comparisons |will |we |use |to |study |the |effect |of |light |on |photosynthesis? |- |
CORRECT |ANSWER✔✔-We |will |use |the |spectrophotometer |to |measure |amount |of |
photosynthesis |underwent |in |unboiled, |boiled, |and |dark |unboiled |chloroplasts.
What |molecule |will |we |use |to |monitor |photosynthesis |in |the |experiment? |- |CORRECT |
ANSWER✔✔-DPIP. |It |replaces |NADP+ |as |a |donator |of |e- |to |turn |in |to |the |product |DPIPH, |
replacing |NADPH; |it |turns |from |blue |to |clear |when |reduced |as |it |gains |e- |from |photons.
What |chemical |change |will |the |spectrophotometer |detect |when |photosynthesis |occur? |- |
CORRECT |ANSWER✔✔-DPUP |reducing |and |turning |into |DPIPH |(blue |to |clear)
What |happens |to |blue |dye, |DPIP, |as |photosynthesis |progresses? |What |is |causing |this |change? |-
|CORRECT |ANSWER✔✔-It |turns |from |blue |to |clear |as |it |is |being |reduced |and |turning |into |
DPIPH.
If |no |photosynthesis |occurs, |what |will |happen |to |the |spectrophotometer |measurement? |- |
CORRECT |ANSWER✔✔-It |will |stay |at |a |higher |absorbency |reading |and |won't |go |down.
What |treatments/ |comparisons |will |we |use |to |study |the |rate |of |respiration |and |photosynthesis
|of |a |plant? |- |CORRECT |ANSWER✔✔-Using |a |CO2 |gas |chamber |to |detect |the |amount |of |CO2 |
being |consumed |between |leaves |in |the |dark |and |light.
How |will |we |monitor |respiration |and |photosynthetic |carbon |fixation? |- |CORRECT |ANSWER✔✔-
By |using |a |CO2 |gas |sensor/ |electrode
, A |computer |program |will |be |recording |the |measurements |of |CO2 |levels. |These |will |be |on |the |
7-axis. |What |will |be |on |the |x-axis? |- |CORRECT |ANSWER✔✔-Time, |in |minutes
What |is |the |equation |for |photosynthesis? |- |CORRECT |ANSWER✔✔-6H2O |+ |6CO2 |+ |light |
energy |-> |C6H12O6 |+ |6O2
What |is |the |equation |for |light |reactions |of |photosynthesis? |- |CORRECT |ANSWER✔✔-H2O |+ |
photons |+ |ADP |+ |NADPH+ |-> |O2 |+ |NADPH |+ |ATP
What |is |the |equation |for |the |Calvin |Cycle |of |photosynthesis? |- |CORRECT |ANSWER✔✔-CO2 |+ |
H2O |+ |RUBP |-> |G3P |+ |NADP |+ |ADP
In |the |graph |made |by |the |CO2 |gas |sensor, |what |slope |did |the |dark |treatment |exhibit? |- |
CORRECT |ANSWER✔✔-Positive
In |the |graph |made |by |the |CO2 |gas |sensor, |what |slope |did |the |light |treatment |exhibit? |- |
CORRECT |ANSWER✔✔-Negative
What |are |the |pop |beads |meant |to |represent |in |lab |8? |- |CORRECT |ANSWER✔✔-Chromatids
When |a |cell |undergoes |mitosis, |how |will |the |chromosomes |of |the |resulting |cells |resemble |the |
original |cell? |- |CORRECT |ANSWER✔✔-The |chromosome |number |and |genetic |information |will |
be |identical.
What |five |stages |of |mitosis |were |studied |in |lab |8? |- |CORRECT |ANSWER✔✔-Prophase, |
prometaphase, |metaphase, |anaphase, |and |telophase
When |a |cell |undergoes |meiosis, |how |will |the |chromosomes |of |the |resulting |cells |resemble |the
|original |cell? |- |CORRECT |ANSWER✔✔-They |will |have |half |the |number |of |chromosomes |as |the |
original |cell, |but |each |cell |will |be |genetically |distinct |from |the |other.
