- 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
- 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 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
