How does the structure of the chloroplast enable it to build up a concentration gradient of protons?
The membrane inside the thylakoid of the chloroplast pumps H+ ions from the outside compartment (stroma) to the inside (lumen). This builds the gradient. The electrons are pumped using energy released from a high energy electron which was energized through light absorption. This electron comes from the breakdown of water.
Where in the chloroplast is the H plus concentration highest?
The chloroplast is the hydrogen ion concentration is highest in the spaces of its thylakoid membrane. The ions get pushed into these spaces during the transportation of electrons.
What will happen if plants which need don't get sunlight?
The photons for sunlight will not transfer energy to the electrons in photosystem 1 & 2, leading to not enough energy for the ETC to pump H+ into the lumen of the thylakoid and produce ATP for the Calvin cycle.
How is gradient of ions maintained in the mitochondria?
By the action of electrons going down the electron transfer chain the energy is provided to pump H + into the outer lumen of the mitochondria creating the concentration gradient for H + to come down it's concentration gradient through the ATP synthase.
What is H ion concentration of ph11?
The following equation will get you to the answer where [H+] is the concentration of hydrogen ion: pH = -log( [H+] ) or [H+] = 10-pH

A high concentration of H in the thylakoid compartment provides energy for what?
A high concentration of H in the thylakoid compartment provides energy for the production of ATP and ATP synthase. ATP is responsible for the transportation of chemical energy within cells, which is necessary for metabolism.

What event contributes directly to the creation of a proton gradient across the thylakoid membrane?
the flow of electrons through electron transport chain II

What is H plus concentration gradient?
It is the concentration difference.If H+ concentration high in a place and low in another place,there is a H+ gradient.
What is a measure of the h concentration in a solution?
The measure of the H+ concentration is the pH.
In photosynthesis an H plus ion gradient froms across what?
across the thylakoid membrane
What is H ion concentration of ph11?
The following equation will get you to the answer where [H+] is the concentration of hydrogen ion: pH = -log( [H+] ) or [H+] = 10-pH
How would the equilibrium concentration of H½O be affected by removing H½ from the mixture?
concentration decreases
