In photosynthesis, as electrons are passed down the electron transport chain, what accumulates inside the thylakoids?
Homework Answers
Answer is hydrogen ions.
As the free electron travels through the electron transport chain, the energy of the electron is used to pump hydrogen ions from the stroma into the thylakoid lumen. Accumulation of hydrogen ions inside the thylakoid lumen creates a concentration gradient. Then, the hydrogen ions diffuse from their high concentration area (the thylakoid lumen) to low concentration area (the stroma) and ATP is created.

What happens along an electron transport chain?
What happens along an electron transport chain? Electrons are passed from a reducing agent to an oxidizing agent, releasing free energy at each step. Electrons are passed from molecule to molecule, gaining potential energy at each step. O Electrons store energy that can be used to break down sugar molecules. O Protons are pumped through ATP synthase, making ATP.

Cellular respiration: The Electron Transport Chain The breakdown of glucose ends during the Krebs cydle; however, it is important to note that the energy previously contained in glucose is mostly stored in NADH and FADHz. In the last step of celular respiration, the high-energy electrons within NADH and FADH2 are passed within a set of proteins found in the inner membrane of the mitochondrion, collectively known as the electron transport chain. The electrons provide the energy to create ATP, which...
