Bio 1500 - Exam 2 -(Mizzou-Bush) Test
Questions and All Correct Answers.
the process by which light energy is used to make food molecules from CO2 and water - Answer
photosynthesis
where does photosynthesis take place? - Answer in chloroplasts
where does photosynthesis take place? - Answer in chloroplasts
molecules that absorb light of a particular wavelength or color - Answer pigment
which wavelengths do chlorophyll absorb? - Answer violet, blue and red wavelengths
when a substance absorbs light energy and re-emits it at a different wavelength - Answer
florescence
when light energy bounces of an object and is not absorbed - Answer reflection
when chemical reactions generate light energy - Answer bioluminescence
what happens when a proton is absorbed by a molecule? - Answer -it excites an electron
into a higher energy state
-the electron quickly drops to its ground state
-releases the energy as light at a longer wavelength
why does isolated chlorophyll in a tube fluoresce red light, but a leaf doesn't? - Answer in
the leaf, the chlorophyll is coupled to a series of chemical reactions that use the light energy. in
the tube, it emits red light due to a mixture with acetone

-define, duplicate, list, memorize, repeat, state - Answer remember
-explain ideas or concepts
-classify, describe, discuss, explain, identify, locate - Answer understand
, -use information in new situations
-execute, implement, solve, use, demonstrate - Answer apply
-draw connections among ideas
-differentiate, organize, relate, compare, contrast - Answer analyze
-justify a stand or decision
-appraise, argue, defend, judge, select - Answer evaluate
-produce new or original work
-design, assemble, construct, conjecture - Answer create
what are the four classes of organic molecules? - Answer -carbohydrates
-lipids
-proteins
-nucleic acids
-composed of C, H, & O atoms
-source of energy, recognition molecule & part of RNA and DNA - Answer carbohydrates
-made of fats, oils, and waxes
-major component to cell membranes, long-term storage and signaling - Answer lipids
-made of nucleotides
-composed of genetic material inherited in humans
-DNA = master code for protein assembly
-RNA = manufacturing of proteins - Answer nucleic acid
-play role in regulating molecules involved in catalysis; cellular signaling - Answer proteins
produces ATP - Answer mitochondria
