What are the metabolic roles of ATP, NAD+, and NADPH in photosynthesis and cellular respiration? What is the net ATP production after glycolysis and Krebs cycle in aerobic respiration? Which steps in cellular respiration use oxidative phosphorylation...
In chloroplasts, the redox status of protein Cys and metabolites is dominated by inputs of electrons and H2O2from photosynthesis. Stromal metabolism has only a minor impact during active photosynthesis. Compared with other compartments, photosynthetic electron transport ...
Cellular respiration is a biological event that occurs for living organisms such as humans. It has 3 different biological pathways involved for the event to spontaneously occur. The 3 biological pathways are the Glycolysis, Kreb's Cycle (Citric Acid Cycle), and the Electron Transport Chain. Each...
However, apart from the central role in circadian synchronization and sleep promotion in humans exerted by melatonin produced by the pineal gland, melatonin is a versatile and ubiquitous molecule, also produced by extrapineal peripheral tissues, that exerts a wide variety of ...
ATP and NADPH produced by the light reactions are used in the Calvin cycle to reduce carbon dioxide to sugar. The Calvin cycle actually produces a three-carbon sugar glyceraldehyde 3-phosphate (G3P). ... Do plants make all their ATP by photosynthesis?
(i) It releases molecular oxygen as by product of photosynthesis and is the significant source of oxygen in air, or is essential for all living beings on earth. (ii) Hydrogen ions produced, are utilised in reducing NADP to NADPH, a strong reducing agent. (iii) The electrons relased are ...
The nicotinamide adenine dinucleotide phosphate (NADPH) oxidases (NOX) and dual oxidases (DUOX), that produce O2.− and H2O2, have been found as a major source of oxidants in cancer cells. NOXs enzymes are also present in such as colon cancer cells (where they regulate proliferation) or...
