What is the purpose of moving hydrogen ions into the thylakoid space in the light dependent reaction?

What is the purpose of moving hydrogen ions into the thylakoid space in the light dependent reaction?

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.

Why must the light-dependent reactions occur in the thylakoid membrane of the chloroplast?

The light-dependent reactions of photosynthesis take place within the thylakoids. These reactions occur when the pigment chlorophyll, located within the thylakoid membranes, captures energy from the sun (photons) to initiate the breakdown of water molecules.

What purpose does the thylakoid space serve during the light reactions of photosynthesis?

The ions flow through ATP synthase from the thylakoid space into the stroma in a process called chemiosmosis to form molecules of ATP, which are used for the formation of sugar molecules in the second stage of photosynthesis.

What happens in the thylakoid space during photosynthesis?

The chloroplast is involved in both stages of photosynthesis. The light reactions take place in the thylakoid. There, water (H2O) is oxidized, and oxygen (O2) is released. The electrons that freed from the water are transferred to ATP and NADPH.

What action contributes to the inside of the thylakoid membrane become positively charged?

What action contributes to the inside of the thylakoid membrane becoming positively charged during the light-dependent reactions? H+ ions are released as water splits. ATP synthase allows H+ ions to pass through the membrane.

Which reaction releases hydrogen ions inside the thylakoid?

Consequently, the oxidation of water during light reaction II leads to release of hydrogen ions (protons) into the inner thylakoid space.

What purpose does the thylakoid space serve during the light reactions of photosynthesis quizlet?

~The light-dependent reactions in plants occur in the thylakoid membrane. The light dependent reactions require photosynthetic pigments that are found embedded in the thylakoid membrane.

What is the purpose of the stacks of thylakoid membrane within the chloroplast?

Inside the chloroplasts are stacks of discs called thylakoids. They are compared to stacks of coins within the walls of the chloroplast, and they act to trap the energy from sunlight.

What happens in the thylakoid space?

Reactions performed in the thylakoid include water photolysis, the electron transport chain, and ATP synthesis. Photosynthetic pigments (e.g., chlorophyll) are embedded into the thylakoid membrane, making it the site of the light-dependent reactions in photosynthesis.

What is inside the thylakoid membrane?

Thylakoids are membrane-bound compartments inside chloroplasts and cyanobacteria. They are the site of the light-dependent reactions of photosynthesis. In thylakoid membranes, chlorophyll pigments are found in packets called quantasomes. Each quantasome contains 230 to 250 chlorophyll molecules.

Which of the following is inside the thylakoid membrane?

chlorophyll
ATP synthase allows H+ ions to pass through the thylakoid membrane. ATP and NADPH are used to produce high-energy sugars. thylakoids. chloroplasts….Figure 8-1.

a.	A chloroplast contains stroma.
d.	A thylakoid contains chlorophyll.

Why do hydrogen ions flow from the thylakoid space to the stroma through ATP synthase?

the electrons are passed down the electron transport chain. electrons are passed from protein to protein to protein releasing energy. hydrogen ions flow from the thylakoid space to the stroma through ATP synthase causing it to spin, releasing energy, then the energy is pciked up by ADP and a phosphate forming ATP.
