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 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. WebThe ATP and NADPH from the light-dependent reactions are used to make sugars in the next stage of photosynthesis, the Calvin cycle. In another form of the light reactions, called cyclic photophosphorylation , electrons follow a different, circular path and only ATP (no … The Calvin cycle, also called the light-independent reactions, takes place in the … The difference is that plants (and photosynthetic bacteria) don't need to … canadian made baby furniture

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. 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.
