How many electron transport chains are there in photosynthesis?
There is one electron transport chain in photosynthesis, which is located in the thylakoid membrane of the chloroplast. This electron transport chain is responsible for transferring electrons and generating ATP and NADPH during the light-dependent reactions of photosynthesis.
Photosynthetic electron transport in cyanobacteria takes place where?
Photosynthetic electron transport in cyanobacteria takes place in thylakoid membranes within the chloroplasts. These membranes contain the pigment chlorophyll, which captures light energy. The electron transport chain within these membranes is essential for the generation of ATP and NADPH, which are used in the production of carbohydrates during photosynthesis.
The function of the electron transport proteins in the thyakoid membranes is?
The function of the electron transport proteins in the thylakoid membranes is to pump hydrogens into the thylakoid space for later generation of ATP. This process is called chemiosmosis.
What uses energy from the high-energy electrons to transport hydrogen across the thylakoid membrane?
The protein complex ATP synthase uses the energy from high-energy electrons to transport hydrogen ions across the thylakoid membrane during the process of photosynthesis. This creates a proton gradient that drives the production of ATP, which is an important energy carrier in the cell.
In mitochondria the electron transport chain pumps protons from the matrix into the intermembrane space whereas in chloroplasts the electron transport chain pumps protons from?
In chloroplasts, the electron transport chain pumps protons from the stroma into the thylakoid lumen. This creates a proton gradient across the thylakoid membrane, similar to the proton gradient established in mitochondria. The energy from this gradient is then used to synthesize ATP through ATP synthase during the process of photophosphorylation.
The photosynthetic electron transport causes the accumulation of protons in which part of the chloroplast?
The accumulation of protons occurs in the thylakoid space within the chloroplast during photosynthetic electron transport. This forms a proton gradient that drives ATP synthesis during the process of photophosphorylation.
What structure that is found in the thylakoid membrane is important to chemiosmosis?
ATP synthase is the structure found in the thylakoid membrane that is important for chemiosmosis. It is responsible for generating ATP by utilizing the proton gradient created during the photosynthetic electron transport chain.

Where does cyclic electron transport occur?
Cyclic electron transport occurs in the thylakoid membrane of chloroplasts during the light reactions of photosynthesis. It involves the flow of electrons through the photosynthetic electron transport chain to generate ATP without the production of NADPH.
What traces the flow of protons through the thylakoid?
trace the flow of protons through the thylakoid
Why is there a large concentration of H in the thylakoid lumen?
There is a large concentration of H+ in the thylakoid lumen due to the proton pumping action of the electron transport chain during photosynthesis. This creates a proton gradient that is used to drive ATP synthesis during the light reactions.
What three things are found in the thylakoid membrane?
Chlorophyll molecules: Responsible for capturing light energy during photosynthesis. Electron transport chain proteins: Facilitate the transfer of electrons during the light-dependent reactions. ATP synthase enzyme: Generates ATP by utilizing the proton gradient established across the thylakoid membrane.
Chemiosmosis in the thylakoid membrane is directly responsible for?
Chemiosmosis in the thylakoid membrane is directly responsible for the generation of ATP during photosynthesis. It involves the movement of protons across the thylakoid membrane to create a proton gradient, which drives the synthesis of ATP by ATP synthase enzyme.
What event contributes directly to the creation of a proton gradient across the thylakoid membrane?
The flow of electrons through the photosynthetic electron transport chain contributes directly to the creation of a proton gradient across the thylakoid membrane. As electrons move through the chain, they pump protons from the stroma into the thylakoid lumen, generating the proton gradient used for ATP production during photosynthesis.
