What is energized in photosynthesis?
A photon of light hits chlorophyll, causing an electron to be energized. The free electron travels through the electron transport chain, and the energy of the electron is used to pump hydrogen ions into the thylakoid space, transferring the energy into the electrochemical gradient.
What do energized electrons do in photosynthesis?
Chlorophyll, which is present in the photosystems, soaks up light energy. The energized electrons are then used to make NADPH. The electron transport chain is a series of molecules that accept or donate electrons easily.
In which organelle does ATP get energized during photosynthesis?
In the chloroplast interior, the thylakoid membrane is folded into numerous flattened vesicles; the light-capturing and ATP-generating reactions of photosynthesis occur on this membrane (see Figure 16-34). Photosynthesis in plants can be described in four stages, which occur in specific parts of the chloroplast.
Does photosynthesis use Chemiosmosis?
The light reactions of photosynthesis generate ATP by the action of chemiosmosis. These protons then flow down their electrochemical potential gradient through an enzyme called ATP-synthase, creating ATP by the phosphorylation of ADP to ATP.
How is Chemiosmosis involved in aerobic respiration?
Chemiosmosis is involved in the production of adenosine triphosphate (ATP), which is the main molecule used for energy by the cell. Through oxygen and glucose, ATP is ultimately created through the phosphorylation of ADP. In aerobic respiration, 38 ATP molecules are formed per glucose molecule.
How is ATP made during photosynthesis?
ATP is produced on the stromal side of the thylakoid membrane, so it is released into the stroma. The electron arrives at photosystem I and joins the P700 special pair of chlorophylls in the reaction center. This process requires light to be absorbed twice, once in each photosystem, and it makes ATP .
What reaction takes place during photosynthesis?
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
What is the role of chemiosmosis in energy production?
Function of Chemiosmosis Chemiosmosis is involved in the production of adenosine triphosphate (ATP), which is the main molecule used for energy by the cell. This energy allows protons (H+) to travel down a proton gradient via chemiosmosis. This in turn provides the energy for the enzyme ATP synthase to make ATP.
