What is the role of hydrogen ion gradient used for in cellular respiration in the mitochondria?
The hydrogen ion gradient is used to drive ATP synthesis. 32 to 34 molecules of ATP are produced. The hydrogen ion gradient is the result of NADH in the electron transport system of the mitochondria.
What intrinsic protein is responsible for maintaining the H ion gradient?
Proton pumps as well as ATP synthase operating in reverse maintain the hydrogen ion gradient of a cell.
What type of ion is built into gradient so ATP synthase can work?
H+ ions (protons) are built into a gradient.
Do organisms always maintain the hydrogen ion concentration gradient?
No, organisms do not always maintain the hydrogen ion concentration gradient. Disruption of the hydrogen ion concentration gradient can occur due to factors such as illness, physical stress, or exposure to toxins, which can affect cellular processes and overall health.
What is the hydrogen ion gradient maintained by?
The hydrogen ion gradient is maintained by the electron transport chain during cellular respiration. This process uses the energy from electrons to pump hydrogen ions across the inner mitochondrial membrane, establishing a gradient that drives the production of ATP through ATP synthase.

Why is the transmembrane potential is important?
The transmembrane potential is important because it helps to maintain the resting state of a cell, allows for the propagation of action potentials, and contributes to various cellular processes such as ion transport, signaling, and cell communication. Changes in transmembrane potential can have significant effects on cellular function and overall physiology.
Is a protein that forms an ion channel through a membrane is most likely to be a peripheral protein a trans membrane protein a phospholipid an enzyme or an entirely outside the phospholipid?
A protein that forms an ion channel through a membrane is most likely to be a transmembrane protein. Transmembrane proteins span the lipid bilayer, allowing them to create channels for ions to pass through the membrane. Peripheral proteins are typically found on the surface of the membrane and do not form channels.

H+ ions (protons) are built into a gradient.

What are the major events of an action potential and what ion changes are associated with each event?
An action potential is a chain reaction of cell events caused by an ionic gradient. One example is the firing of a nerve reaction.
What is the hydrogen ion gradient maintained by?
The hydrogen ion gradient is maintained by the electron transport chain during cellular respiration. This process uses the energy from electrons to pump hydrogen ions across the inner mitochondrial membrane, establishing a gradient that drives the production of ATP through ATP synthase.
Is Na K pump active or passive?
In biology, an ion transporter, also called an ion pump, is a transmembrane protein that moves ions across a plasma membrane against their concentration gradient, in contrast to ion channels, where ions go through passive transport.
In photosynthesis an H plus ion gradient froms across what?
In photosynthesis, an H+ ion gradient forms across the thylakoid membrane of the chloroplast. This gradient is established through the process of electron transport chain and proton pumping during the light reactions, which leads to the generation of ATP via chemiosmosis.
Which process moves an ion across a cell membrane against a concentration gradient?
ative transport
What is the driving force of the membrane?
The driving force is explained by two factors: voltage gradient and concentration gradient. When there are more ions inside of a cell than outside of a cell, the concentration gradient is pushing the ion to exit the cell. This is simple diffusion. If that ion carries a negative charge then it also wants to exit the cell because the outside environment is slightly more positive.So if you add both voltage gradient and concentration gradient you get the driving force. In the example above both gradients are pushing the ion outside of the cell. Sometimes you can have the gradients going in opposites and then the driving force will be determined on which gradient is stronger.
