What portion of the illuminated plant cell would you expect to have the lowest pH?
The thylakoid space
What is the function of a lumen?
The thylakoid lumen is the compartment bounded by the thylakoid membrane. It plays a vital role for photophosphorylation during photosynthesis. During the light-dependent reaction, protons are pumped across the thylakoid membrane into the lumen making it acidic down to pH 4.
Why are acidic substances lower in pH value than basic substances?
because the substance is high on pH value because the substance is high on pH value
What side of the thylakoid membrane is the Ph the lowest?
The phytoplankton side containing the polypeptoglycan peenuss
Does a low pH decrease hemoglobins affinity for oxygen?
Yes. This an example of the Bohr effect. If pH is lower than normal (normal is 7.4), then hemoglobin does not bind oxygen as well. The higher the pH, the lower the H ion concentration, the lower the carbon dioxide level, and the GREATER affinity hemoglobin has for oxygen. The binding of oxygen to hemoglobin in the lungs is not affected by changing the pH.
Is there a relationship between the pH of the inner thylakoid space and the pH of the stroma?
yes
Which compartment in chloroplasts is likely to have the lowest pH?
The inside of the thylakoid disks will have the lowest pH. This is because of the pumping of protons into this area. Hydrogen ions will increase which is a decrease in pH.
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.
What does it mean when a pH is lower than seven?
When the pH is lower than 7, the solution is 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.
Describes a solution with a pH lower than the pH of distilled water?
Water is neutral (pH 7). Lower numbers than 7 are acids- the lower the number, the stronger the acid.
What will happen to the pH inside of a thylakoid that is exposed to light?
It will decrease.
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.
Do bases have a pH of more than 7?
Yes acids have a pH lower than 7
Is pH 9 more acidic than pH 4?
no. the lower the pH the more acidic
When rainfall what is the reading on the pH scale lower than 5.6?
if rainfall has reading on the pH scale lower than 5.6 it is called Acid Rain.
PH of 4 than a solution with a pH of 5?
a pH of 4 is most acidic than a solution with a pH of 5. In general, the lower the pH, the more acidic the solution is.
