Is Mg involved in electron retention or release form chlorophyll? Yes or no?
Though it is seen that Mg as in whole play no self importance but it is true that during the process of photosynthesis Mg is doing the work of e- removal beside of the fact that these reaction suggest that fact.
Is Mg involved in electron retention or release form chlorophyll? Yes or no?
1A- What happens whej light "excites" an electron of a chlorophyll molecule? A- The electron moves to an electron shell that is further from the nucleus B- Nothing. Light does not have this effect on electrons C- The electron moves to an electron shell that is closer to the nucleus D- An electron is transferred to another molecule 1B- What molecule is oxidized in order to reduce the special chlorophyll a pair? A-Water B-Glucose C- None. The special chlorophyll pair...
Draw a graph of absorbance of chlorophyll across usual wavelengths which structure in the chloroplasts involved in the absorbance of photons?
1.) Light absorbed by a chlorophyll a causes: A) An electron to move to a neighboring water molecule B) An electron to move from ground state to an excited state C) An electron to move from chlorophyll to ADP D) Non of the answers is correct 2.) Which of the following is/are light harvesting molecules? A) Plastocyanin B) Carotenoids C) Carotenoids and chlorophyll b D) Vitamin D 3.) What evidence eists to support an endosymbiotic event for the formation of...
Cells generate ATP from the release of chemical energy from nutrients, whereas chlorophyll-containing organisms generate ATP via the light-dependent reactions of photosynthesis as well as from the oxidation of nutrients. true or false
Is there a difference between data retention and data archival? If yes, describe the difference. If no, describe the similarities.

The enzymes involved in the electron transport chain are located in the: A) Mitochondrial matris B) Mitochondrial inner-membrane Mitochondrial inner-membrane space D) Mitochondrial outer-membrane 2. Which of the following is not classified as a micronutrient? A) Vitamins B) Antioxidants C) Minerals D) Water 3. The metabolic reaction pathways that break down food molecules are known as: A) Anabolism and release biochemical energy B) Anabolism and require biochemical energy Catabolism and release biochemical energy D) Catabolism and require biochemical energy...
Question 3 (2 points) The Mg- metal ions involved in the enolase reaction mechanism are required for which reason? They allow a Lys in the active site to donate a proton to the 2-phosphoglycerate substrate They prevent the reverse catalysis of 3-phosphoglycerate to 2-phosphoglycerate They stabilize the phosphate group of 2 phosphoglycerate they enhance the electron withdrawing potential of the carbonyl group of 2-phosphoglycerate. they form covalent bonds with a prophyrin ring to coordinate the substrate
Some people are actively involved in promoting and supporting a cause such as the release of intentional political prisoners or protecting the environment. Write an essay convincing readers to support that cause.
