What powers the proton gradient of positive ions in the stroma?
proton gradient
What type of ion is built into gradient so ATP synthase can work?
H+ ions (protons) are built into a gradient.
What forces hydrogen ions to flow through the F0 subunit?
a concentration gradient
What two ions move up their concentration gradient in this pump?
glucose & sodium
What does a difference in concentration in a cell create?
a concentration gradient
What powers the proton gradient of positive ions in the stroma?
proton gradient
How are NaCl and water reabsorbed in proximal tubule?
Mitochondria are needed in order to supply the energy for the active transport of sodium ions out of the cells in the proximal tubule to create a concentration gradient which allows more sodium ions to enter the cell from the luminal side.Water passively follows the sodium out of the cell along its concentration gradient.
What type of ion is built into gradient so ATP synthase can work?
H+ ions (protons) are built into a gradient.
What does a difference in concentration create?
Gradient
When hydrogen ions are pumped from the mitochondrial matrix across the inner membrane and into the intermembrane space the result is?
Hydrogen ions are pumped through the membrane in the final stage of ATP generation in the electron transport chain. The ions pumped through the membrane create a gradient and cause the hydrogen to "want" to pass back through the membrane. They do so through the protein channels in the membrane and attaches a phosphate to adenosine diphosphate to make adenosine triphosphate.
What forces hydrogen ions to flow through the F0 subunit?
a concentration gradient
What two ions move up their concentration gradient in this pump?
glucose & sodium
Do acids create hydroxide ions when dissolved in water?
No, acids do not create hydroxide (OH-) ions when dissolved in water. Acids create Hydrogen (H+) ions when dissolved in water.Bases create hydroxide ions when dissolved in water.
What two forces drive the passive transport of ions across a membrane?
Two forces drive the passive transport of ions across a membrane: -the concentration gradient of the ions -the effect of membrane potential (voltage) on the ions
What does a difference in concentration in a cell create?
a concentration gradient
What is the difference between concentration gradient of molecule and ions?
dont know ask someone else
What is a differences in concentration called?
concentration gradient
