What side of the thylakoid membrane is the Ph the lowest?
The pH is lowest on the lumen side of the thylakoid membrane during photosynthesis. This is because protons are pumped into the thylakoid lumen as part of the electron transport chain, creating an acidic environment that helps drive ATP production through chemiosmosis.
Why are acidic substances lower in pH value than basic substances?
Acidic substances have higher concentrations of hydrogen ions (H+) which results in a lower pH value compared to basic (alkaline) substances. A lower pH value indicates a higher concentration of H+ ions, while a higher pH value indicates a higher concentration of hydroxide ions (OH-) found in basic substances.
What is more acidic a pH of 2 or 3?
pH 2. The lower the number is the more acidic it is. pH 7 is neutral, pH 14 is least acidic. 5.4 is considered acid rain.
What portion of the illuminated plant cell would you expect to have the lowest pH?
The portion of the illuminated plant cell expected to have the lowest pH is the vacuole. This is because the vacuole is responsible for storing and regulating the cell's pH by actively pumping protons and other ions.
Charge of amino acid at pH 1?
At pH 1, the amino acid will be fully protonated because the pH is lower than its pKa value. This means that the amino acid will have a positive charge, as the amino group will be protonated.
Is there a relationship between the pH of the inner thylakoid space and the pH of the stroma?
yes
During electron transport the thylakoid space becomes?
During electron transport in the thylakoid membrane, the thylakoid space becomes more acidic (lower pH) as protons are pumped into this space by electron transport chain components, creating a proton gradient. This proton gradient is essential for ATP synthesis during the light reactions of photosynthesis.
Which compartment in chloroplasts is likely to have the lowest pH?
The thylakoid lumen is likely to have the lowest pH in chloroplasts due to the accumulation of protons during the light-dependent reactions of photosynthesis.
Why does the pH of the cell become more basic during photosynthesis?
During the light reactions of photosynthesis, protons (H+) are ferried into the thylakoid space using the energy from the excited electrons in Photosystems 680 and 700. H+ causes buildup of hydronium (H3O+) ions in water, which are acidic.
Which acids have a pH lower than 4.6?
There are many acids that have a pH lower than 4.6. Hydrochloric acid for example has a pH of less than 2.
How does the pH of an acid compare with the pH of a neutral solution?
The pH of an acid is lower than that of a neutral solution. Acids have a pH less than 7, with stronger acids having lower pH values. A neutral solution has a pH of 7.
What does it mean when a pH is lower than seven?
When the pH is lower than 7, the solution is acidic.
What will happen to the pH inside of a thylakoid that is exposed to light?
It will decrease.
What pH level do acids have?
Acids have a pH level lower than 7, typically ranging from 0 to 6.9. The lower the pH value, the stronger the acid.
Is pH of a basic solution higher or lower than pH of a acid solution?
A basic pH is higher than an acidic or neutral pH.
Describes a solution with a pH lower than the pH of distilled water?
A solution with a pH lower than that of distilled water would be acidic. This could be achieved by adding an acid such as hydrochloric acid or sulfuric acid to water. Acidic solutions have a pH below 7, with the lower the pH, the more acidic the solution will be.
What sentence correctly describes a solution with a pH lower that the pH of distilled water?
A solution with a pH lower than that of distilled water is considered acidic.
