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