What is the energy of hydrogen ion gradient created across the inner mitochondrial membrane used to make?
The hydrogen falls down its electrochemical gradient, from an area of high concentration to an area of lower concentration, through the ATP synthase and provides the force to power this synthase and synthesize ATP.
What is the energy of the hydrogen ion gradient created across the inner mitochondrial membrane used to make?
electron transport chain
Osmotic pressure is created by the presence in a fluid of small difusible moleules that easily move through the capillary membrane?
Osmotic pressure is the force exerted by the movement of solvent molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. This movement equalizes the concentration on both sides of the membrane. The osmotic pressure is directly proportional to the concentration of solute particles in the fluid.
What process does water enter root hair cells?
BY osmosis i.e the concentration gradient created between the outside and the root hairs cells. Water will flow from a high area of concentration to a low area of concentration across a partially permeable membrane
Why do protons accumulate outside the membrane and why is this necessary?
Protons accumulate outside the membrane, so that a concentration-gradiënt is established. Because of this the protons want to flow inside, and this "current of protons" is enhanced by a membrane enzyme, called ATP-synthase to produce ATP. So, basically a potential is created, which can power the production of ATP.

How do molecules diffuse?
Movement of solutes across a lipid bilayer plasma membrane can occur in many ways:1. Osmosis: diffusion of water across membranes to balance solute concentrations.- No energy req- Water passes through membrane via aquaporins, pores in the membrane permeable only to water.2. Simple diffusion: diffusion of only small, hydrophobic (nonpolar) molecules across a membrane down their concentration gradient.- No energy req- Only moves small nonpolar molecules down their concentration gradient3. Facilitated diffusion (passive transport): uses transmembrane protein transporters (channels and carriers) to move polar molecules (ions) across a membrane- No energy required- Channel proteins: Allow for rapid diffusion of specific ions down their concentration gradient- Can be activated by:- Voltage- Ligand- Mechanical force- Carrier proteins: Allow for selective diffusion of specific ions down their concentration gradient.- Uniport carriers: only transport one specific ion down its concentration gradient- Symport carriers: move two different types of ions in the same direction.- Antiport carriers: moves two different ions in opposite directions-Can use the energy created moving one molecule down its concentration gradient to move an ion against its concentration gradient- Carrier proteins exhibit saturation, competition, and specificity.4. Active transport: transport of solutes across a membrane against their concentration gradient.- ATP req- Uses carrier proteins- Leads to creation of potential energy stored in electrochemical gradients
What portion of the mitochondria has the lowest pH?
According to another answer to a similar question here on this site, "The intermembrane space has the lowest pH, highest concentration of H+, due to the gradient created by the electron transport chain."
When was Gradient Analytics created?
Gradient Analytics was created in 1996.

What is the role of ATP synthase and how does is work?
ATP synthase is a key enzyme in energy transformation of a living cell. The enzyme makes adenosine triphosphate (ATP) from adenosine diiphosphate (ADP) and inorganic phosphate (Pi). ADP + Pi <=> ATP ATP is a universal "energy currency" of a living cell and is essential for DNA synthesis, muscle contraction, ion and nutrients transport, signal transduction, etc. The amazing feature of ATP synthase is rotary catalysis: a complex of subunits rotates relative to the rest of the enzyme and the mechanical energy of rotation is driving ATP synthesis reaction. In turn, the rotation is powered by transport of protons trough the membrane segment of ATP synthase. The driving force for this transport is the electrochemical potential difference of proton across the membrane. ATP synthase is therefore the smallest mechano-electro-chemical energy transducer that works as a nanoturbine. A much more detailed description of ATP synthase is available at www.atpsynthase.info
What is needed to move particles from areas of low concentration to high concentration?
Because the concentration is going up so much energy is needed to do this. If the cell was going from a high concentration to a low, no energy is needed because it is already at a high concentration and its going lower you wouldn't need any energy to go lower at a high stance
