This is a question our experts keep getting from time to time. Now, we have got a complete detailed explanation and answer for everyone, who is interested!
The photolysis of water, H+ pumping, and NADP reductase activity in the stroma all contribute to a greater proton concentration in the lumen of thylakoids.
Within the chloroplast, where can protons be found?
During a reaction that is light-dependent, protons are injected through the thylakoid membrane into the lumen. This causes the lumen to become acidic, with a pH level of 4. According to the chemical hypothesis, the creation of the proton gradient in the membrane of the thylakoid is linked to the synthesis of ATP.
In chlorophyll, the highest concentration of protons is found in the cytoplasm.
- Lumen of thylakoids. 72%
- Inter membrane space. 11%
- Antennae complex. 5%
- Stroma. 11%
Where exactly in the chloroplast is the proton concentration at its highest?
The thylakoid space, also known as the thylakoid lumen, can be thought of as the region of the chloroplast that contains the greatest number of protons.
Which one contains the greatest quantity of protons?
Uranium is the most massive naturally occurring element, boasting 92 protons in its nucleus.

33 relevant questions found
In a chloroplast, which region has the largest concentration of the cation hydrogen?
The concentration of hydrogen ions is greatest in the spaces of the chloroplast’s thylakoid membrane. Here is where chloroplasts are found.
What is the greatest number of an atomic element?
Oganesson is the element with the greatest atomic number and the highest atomic mass of any element that is currently known. Since 2005, only five (perhaps six) atoms of the isotope oganesson-294 have been found. This is due to the fact that the radioactive oganesson atom is extremely unstable.
In the process of photosynthesis, where is a high concentration of protons found?
Within the thylakoid region, protons build up to a very high concentration when photosynthetic electron transport is taking place. The energy source that the ATP synthase draws its power from is the concentration gradient that exists between the interior and outside of the thylakoids.
Where exactly in the chloroplast does the low H+ proton concentration originate?
The end effect is that there is a relatively low concentration of protons in the stroma but a relatively high concentration of protons in the lumen of the thylakoid membrane. This electrochemical gradient is utilized by ATP synthase in the production of ATP, just as it was in the process of cellular respiration.
Which areas have very high concentrations of protons?
The intermembrane gap within the mitochondria has the highest proton concentration of any part of the mitochondria.
Where exactly may chlorophyll be found inside the chloroplasts?
Inside the thylakoid membrane is where you’ll find the green pigment chlorophyll, and the stroma is the name given to the area between the thylakoid membrane and the chloroplast membranes.
Chloroplasts are present in bundle sheath cells, right?
Mesophyll cells and bundle sheath cells are the two types of photosynthetic cells that are found in C4 plants. Depending on the species of plant, mesophyll chloroplasts are dispersed at random along the cell walls, whereas bundle sheath chloroplasts are always found in close proximity to either the vascular tissues or the mesophyll cells.
At what location within the chloroplast does the light-independent reaction take place?
Within the stroma is where the reactions of photosynthesis that do not require light take place. It has enzymes that, in conjunction with ATP and NADPH, “fix” carbon from carbon dioxide into molecules that can be used to create glucose. This process is called glycolysis. The stroma is where the chloroplast’s own genetic material, which is distinct from the genetic material of the cell, is housed.
What is the total number of phospholipid bilayers found in chloroplasts?
In contrast to mitochondria, chloroplasts are composed of three separate bilayers of phospholipids. And here you were thinking something as simple as a double bilayer was complex!
How many chloroplasts are present in cells that are responsible for photosynthesis?
How many chloroplasts, on average, are present in a cell that is responsible for photosynthesis? Photosynthetic cells contain potentially thousands upon thousands of chloroplasts. 9.
What are the several kinds of proton pumps that can be found in chloroplasts?
There are three varieties of proton pumps: P-type, V-type, and F-type. P-type proton pumps are the most common. H+ transfer is the primary function of the P-type proton pump, which is found in the cell membrane of eukaryotic organisms.
How is it possible for there to be such a high concentration of protons in the lumen of the thylakoid?
Analogy between the processes of Photosynthesis and Oxidative Phosphorylation Protons are driven into the thylakoid lumen as a result of the light-induced electron transfer that occurs during photosynthesis. Via the action of ATP synthase, which is located in the stroma, the surplus protons are expelled from the lumen.
During photosynthesis, how exactly does the proton gradient get formed in the chloroplasts?
This energy is utilized to pump protons from the thylakoid membrane into the thylakoid space, which forms the proton gradient. When the light energy is absorbed, the excited electrons are passed on to the chain of electron carriers that are present within the thylakoid membrane.
What factors contribute to an increase in the total number of H+ protons present in the thylakoid lumen?
A portion of the energy that is passed on from the electrons is utilized to pump hydrogen ions across the membrane so that they can collect in the lumen of the thylakoid. This results in an even greater increase in the area’s H+ content, which ultimately has an indirect impact on the generation of ATP.
Which part of the chloroplast has a higher pH: the matrix or the stroma?
Because all of the H+ travel into thylakoids, the pH level drops inside of them, while the concentration of H+ ions outside drops, causing the pH level outside to rise.
In chloroplasts, as opposed to mitochondria, where are protons transported?
In mitochondria, high-energy electrons are obtained from the food molecule through a process called redox reaction. In chloroplasts, on the other hand, the source of the electrons is the photons that are taken in from the surrounding light. The accumulation of H+ ions in the thylakoid compartment is what causes the formation of the proton gradient (H+).
When photosynthesis is complete, what happens to the electrons?
It is necessary for the electrons to pass through specialized proteins that are anchored in the thylakoid membrane. They continue down the electron transport chain after passing through the first specialized protein, which is the photosystem II protein. After that, they go through a second protein that is uniquely specialized.
Which element has the greatest radius of its individual atoms?
Atomic radii shift in a way that can be predicted as one moves down the periodic table. As can be seen in the graphics that follow, the atomic radius expands from left to right across a group but contracts from top to bottom within a group. This pattern repeats itself over periods. Hence, helium is the most fundamental element, although francium is the most massive.
Can you name the lanthanide with the highest atomic number?
a lanthanoid, also known as a lanthanide, is any of the 15 consecutive chemical elements in the periodic table, starting with lanthanum and going all the way up to lutetium.
Which one of these elements has the greatest number of atoms per nucleon?
Because of this, we may conclude that, out of these three elements, Krypton has the lowest atomicity, while Sulfur has the highest atomicity.
