Hydrogen pumps move hydrogen ions into which structure?
The thylakoid
What hydrogen ion pumps do?
also referred to as "Chemiosmotic Synthesis of ATP", hydrogen ions are removed from one side of the membrane to another. (inside to out), generating a proton gradient across the membrane. So we have a high concn of H+ ions outside the cell membrane. This causes the H+ ions in urgent need to get back inside with diffusion, thus protons move across membrane through special channels. Their passage drives the synthesis of ATP as well. btw this is also Active Transport. (ATP from cell is required).
Why does Hydrogen Chloride not conduct electricity when dissolved in hexane but conducts electicity when dissolved in water?
Water is a polar molecule and hexane is non-polar. This means that water has positive charges that grab on to the negative-chlorine and water has negative charges that grab onto the positive-hydrogen. This pulls the hydrogen and chlorine apart as positive and negative ions. The these positive and negative ions can move around separately as positive and negative electrical carriers. In hexane the hydrogen and chlorine are locked together, a single neutral molecule and no charged ions. Any positive movement of the hydrogen is locked to the negative movement of the chlorine, so any movement balances out to zero charge movement and zero electrical movement.
What do sodium ions move toward in an aqueous solution?
Negative Terminal
Why copper 2 sulfate does not conduct electricity in solid state?
In the solid state, the Cu2+ and SO42- ions are locked into a crystalline structure, and all electrons are locked into place; because electrons are not free to move, no electrical current can flow. Copper (II) Sulfate CuSO4 can only conduct electricity when the ions are separated, as when this compound is dissolved in water. This "disassociation" permits electrons to be removed from the negative ions and added to the positive ions by an electrical potential, resulting in an electrical current.
Hydrogen pumps move hydrogen ions into which structure?
The thylakoid
What is the function of the proton pumps in the thylakoid membranes?
moving hydrogen nuclei out of the thylakoid
Hydrogen ions move from the outer to the inner compartment of the mitochondria through what molecule?
Hydrogen ions move from the outer to the inner compartment of the mitochondria through the electron transport system. The energy used to synthesize ATP.
What ions must routinely move across cellular membranes?
Through diffusion, or facilitated diffusion via protein channels, or active transport via protein channel pumps (active transport goes against the concentration gradient) Most cells in our bodies use active transport to maintain electrolytic balances.
What type of process takes place if the hydrogen ions move without the help of additional energy?
Facilitated diffusion

Where does the energy to move hydrogen ions across the thylakoids membrane come from?
Concentration gradient is made first.Solar energy is used.
What will most likely happen if the hydrogen pump protein in photosystem 2 does not move enough H ions into the thylakoids?
Well, not enough gradient will be built up so hydrogen comes down it's concentration gradient through the synthase and synthesizes ATP. Also NADPH will be adversely affected.
What is a symport system?
A symport system utilizes a carrier protein to move hydrogen and chloride ions from inside to outside of the cell, and requires energy to do this.
Do sodium and chloride ions move around in pairs when in solution?
No, they move around apart from each others, each of them are surrounded by 'hydrogen bonded' water molecules (approx. 20, mantled)
What is formed when enzymes move hydrogen ions across a membrane to an area of greater concentration?
I will say the answer is osmosis or diffusion...I'll go with osmosis. MC
Why ionic compound do not conduct electricity?
Ionic compounds do not conduct electricity when solid because the ions are held in place by a lattice structure which means they are not free to move to conduct. However when molten or dissolved ionic compounds do conduct electricity because the ions are free to move.
