WebMay 4, 2024 · For ATP, energy is released with the loss of the terminal phosphate atom, converting it into ADP; for NADPH, both energy and a hydrogen atom are lost, converting it into NADP +. Both of these molecules return to the nearby light-dependent reactions to be reused and re-energized. Stage 3: Regeneration WebNADPH and ATP molecules now store the energy from excited electrons – energy which was originally sunlight – in chemical bonds. Thus chloroplasts, with their orderly arrangement of pigments, enzymes, and electron transport chains, transform light energy into chemical energy.

WebThe light- reactions occur in thylakoid membranes. 12. Carbon dioxide is used to make sugars in the light- reactions. 13. The light-independent reactions are also called the . 14. spins to provide the energy for adding a phosphate group to ADP. 15. Electron move high-energy electrons between photosystems. 16. WebMar 25, 2024 · According to Nature, mitochondria produce ATP by passing a high-energy electron along an electron transport chain. The high amount of energy from this process pumps hydrogen out of the mitochondrial matrix. This creates a pressure gradient, which drives the hydrogen molecule back through the membrane. WebNov 27, 2024 · ATP is the energy currency of cells. It is the main energy source for most cellular processes, including photosynthesis. In photosynthesis, ATP is used to power the light reactions, which convert solar energy into chemical energy that is used to produce organic molecules from CO2 and water. church farm haven holiday park

WebUsing ATP and NADPH from the light reactions, 3-PG is reduced to glyceraldehyde-3-phosphate (G3P). Two molecules of G3P can spontaneously form a molecule of glucose (the first, energetically-uphill part of glycolysis running backwards). However, they were unable at first to identify a 2-carbon molecule that could bond with CO2 to form 3-PG. WebThe chemiosmotic hypothesis states that the synthesis of ATP generates a proton gradient that leads to electron flow through an electron transport chain. False According to the chemiosmotic hypothesis, what provides the energy that directly drives ATP synthesis? Proton gradient
