Alternative Methods of Carbon Fixation: Plant Structure: Photosynthesis: Metabolism Cellular Respiration
100
This is the evaporative loss of water from leaves
Transpiration
100
These organelles are the site of photosynthesis
Chloroplasts
100
Photosynthesis is the conversion of light energy into what type of energy?
Chemical
100
These are also known as “biosynthetic pathways
anabolic pathways
100
This is the partial breakdown of sugar in the absence of oxygen
Fermentation
200
In the absence of CO2, rubisco will incorporate which molecule into the Calvin cycle?
O2
200
This is the interior leaf tissue that houses the chloroplasts
Mesophyll
200
Particles of light are called:
Photons
200
This is the measure of disorder
entropy
200
These release energy when electrons move closer to an electronegative atoms
redox reactions
300
With no known benefit to plants, photorespiration may be what?
An evolutionary relic
300
These are microscopic pores in a plant’s leaf
Stomata
300
These type of organisms are also known as “self-feeders”
Autotrophs
300
This is the “principle of conservation of energy”
1st law of thermodynamics
300
What is the role of oxygen in cell resp?
Final electron acceptor
400
Give an example of a C4 plant
sugar cane and corn
400
What is the fluid filled interior of the chloroplast called?
Stroma
400
All possible wavelengths of light make up:
The electromagnetic spectrum
400
This is the kinetic energy associated with random movement
heat or thermal energy
400
What enzyme delivers electrons to NAD+ from glucose?
dehydrogenase
500
This enzyme replaces rubisco in C4 photosynthesis
PEP carboxylase
500
Where are ATP synthase proteins located in the chloroplast?
Thylakoid membrane
500
In photosynthesis, the process that forms ATP is called what?
Photophosphorylation
500
What must every spontaneous process do?
Decrease the system’s free energy
500
What enzyme is the key point of regulation for cellular respiration?
phosphofructokinase
