What happens to the hydrogen concentration in the thylakoid and why is this important?
During photosynthesis, the light-dependent reactions occur in the thylakoid membranes of chloroplasts, leading to the splitting of water molecules (photolysis). This process generates oxygen and releases protons (H⁺ ions) into the thylakoid lumen, increasing the hydrogen concentration inside the thylakoids. This proton gradient is crucial as it drives ATP synthesis through ATP synthase, ultimately facilitating the conversion of solar energy into chemical energy in the form of ATP and NADPH, which are essential for the subsequent light-independent reactions.
What else can I help you with?
Where does the light reaction happens?
Light reactions occur in the cells chloroplast
What happens to the number of hydrogen ions if a solution becomes more acidic?
The concentration of hydrogen in a solution increases as the pH of the solution becomes more acidic.
The enzymes for the light dependent reactions are found in the thylakoid membrane while the Calvin cycle happens in the what?
The Calvin cycle happens in the stroma of the chloroplast.
What happens to electrons in the thylakoid membrane?
they return to their original energy levels.
If the hyrdoxide ion concentartion increases what happens to the hydrogen ion concentration?
As the hydroxide ion concentration increases, the hydrogen ion concentration decreases due to the reaction between the two ions. This relationship is governed by the autoionization of water, where water molecules can act as both acids (donating H+) and bases (accepting H+).
What happens to the concentration of hydrogen ions when an acid and a base are reacted?
The concentration of hydrogen ions decreases as they react with hydroxide ions from the base to form water molecules.
What happens to the hydrogen ion concentration as you decrease the pH?
Hydrogen ion concentration increases.
Where does the light reaction happens?
Light reactions occur in the cells chloroplast
What happens to the number of hydrogen ions if a solution becomes more acidic?
The concentration of hydrogen in a solution increases as the pH of the solution becomes more acidic.

What happens to the concentration of hydrogen ions in a 1 moles per liter solution of hydrochloric acid on repeated dilution?
The concentration become more and more lower.
What happens to he hydrogen ion as you decrease the pH?
As you decrease the pH, the concentration of hydrogen ions (H+) increases. This increase corresponds to a higher acidity level. Hydrogen ions are released into the solution as acids dissociate.
What happens to the hydroxide ion concentration in aqueous solutions when you increase the hydrogen ion concentration by adding an acid?
The hydroxide ion concentration would decrease in response to the increase in hydrogen ion concentration. This is due to the neutralization reaction that occurs between the added acid (which releases H+ ions) and the hydroxide ions (OH-) present in the solution.
What happens to the h as the pH of a solution increases?
As the pH of a solution increases, the concentration of hydrogen ions (H+) decreases. This means that the solution becomes less acidic. Due to the inverse relationship between pH and hydrogen ion concentration, as pH increases, the concentration of H+ ions decreases exponentially.
What happens to the pH As the hydrogen ion concentration increases?
as the pH increases in acids, the acids lose their ability to ionise in water, so less hydrogen ions are produced. so stronger acids, like hydrochloric acid with a low pH, produce more hydrogen ions than weaker acids, like ethanoic acid with a high pH.
What happens to electrons in the thylakoid membrane?
they return to their original energy levels.
What happens when electrons are passed the electron transport chain?
Hydrogen ions are pumped across the mitochondria's inner membrane producing a concentration gradient
