it is controlled by isocitrate dehydrogenase and citric formation and is inhibited by ATP
How is water split?
by photosynthesis which splits or oxidizes water
What is the energy that plants use to make food?
light
The higher the ________the more energy is carried by the corresponding photon
frequency
What the energy content of Photons proportional to?
frequency
How are all three energy pathways controlled?
controlled by allosteric control using negative and positive feed back
What yields the highest energy content?
oxidation of glucose through Glycolysis, pyruvate dehydrogenase and citric acid cycle
What do "modern" photoautotrophs produce?
oxygen and carbohydrates
What is the energy not or inversely proportional to?
wavelength of light
_______ describes the coversion of light energy into chemical energy.
Photosynthesis
What important gas does plants produce?
oxygen
How does the interaction between light and matter occur?
through absorption of photons
What does a plant make that all other organisms depend on?
glucose
How can oxygen be provided?
by CO2 or water
what are the single energy units of light and have their own distinct energies ?
Photons
What is the primary sources for plants to make food?
carbon dioxide and light
What has the lowest energy content?
Oxaloacetate
What lights contain short wavelength and contains higher energy than red or infra-red light?
UV, blue light
What is another name for glycolysis?
phosphofructokinase
Light is only a small part of the ___________?
electro-magnetic spectrum
Where does oxygen come from in metabolism?
from the spliting of water
_______ is a form of electro-magnetic energy formed by the sun's thermonuclear reactions that is visible
light
What is the main control in the citric acid cycle and how is it inhibited?
it is controlled by isocitrate dehydrogenase and citric formation and is inhibited by ATP and NADH+H+ but promoted by ADP and NAD
What is excess Acetyl-CoA used for?
the production of fatty acids
What is the main control station for glycolysis and how is it inhibited?
the main control station is phospofructoknase and is is inhibited by ATP
What had "old" photoautotrophs produced?
sulphur
Where does glycolysis (phosphofructokinase) located?
in the cytoplasm but inhibited by ATP and citric acid which are both made in the citric acid cycle
What is the only oxygen that is shows up in the atmosphere?
oxygen that is provided in water
