Yes. Cellular respiration involves three steps: glycolysis, the Krebs Cycle (also called the Citric Acid Cycle) and the Electron Transport Chain. Glycolysis breaks up glucose into two molecules of pyruvic acid, the Krebs Cycle strips away carbon from these pyruvic acids in order to free up electrons, and the Electron Transport Chain takes these electrons and uses oxygen to pull them down a series of proteins, moving hydrogen across the internal membrane of the mitochondria in the process. ATP synthase takes these hydrogen protons as they move back down their concentration gradient and uses them to make ATP.
What else can I help you with?
Why do you think movement of ions through ion channels is generally a slower process that diffusion?
Let's take something obvious. Where would a crowd of persons move faster? Where there is absolutely nothing to prevent their passage or where there is an open gate? The same thing applies to the movement of ions. Movement of ions through ion channels is a slower process because (with a more scientific approach!) their movement is determined by the number of these ion channels whereas for diffusion, there is absolutely nothing to prevent the passage of the molecules.
What structure in the plasma membrane regulate ion passage?
Ion channels and the hydrophilic/hydrophobic/hydrophilic membrane.
A substance that releases hydrogen ions in water is a base yes or no?
Electrolytes that release ions that combine with hydrogen atoms are called bases.
Do proteins prevent ions form crossing cell membranes true or false answer?
False. Proteins in the cell membrane, such as ion channels and transporters, actually facilitate the movement of ions across the cell membrane. They play a crucial role in maintaining cellular function by regulating the passage of ions in and out of the cell.
Are membrane ion channels are examples of integral membrane proteins?
Yes, membrane ion channels are examples of integral membrane proteins. They are embedded within the lipid bilayer of a cell's membrane and mediate the passage of ions across the membrane in a highly regulated manner.
What transport protein allows ions to pass through the cell membrane?
Ion channels are transport proteins that facilitate the passage of ions across the cell membrane by creating a pore for ions to move through. These channels are selective in the ions they allow to pass and can be gated, meaning they can open and close in response to certain signals.
What allows ions to enter the neural cell?
Ions enter the neural cell through ion channels located on the cell membrane. These channels are selective to specific ions based on size and charge, allowing for the passage of ions like sodium, potassium, calcium, and chloride. Ion channels open and close in response to various stimuli, such as changes in membrane potential or binding of specific molecules.

In the membrane of a cell channels serve as what?
Channels in the cell membrane serve as passageways for the selective transport of ions and molecules into and out of the cell. They help maintain the cell's internal environment by controlling the flow of substances across the membrane.
What is hydrogen ion movement?
Hydrogen ion movement refers to the migration of positively charged hydrogen ions (H+) across cellular membranes, which plays a critical role in various biological processes such as cellular respiration and pH regulation. This movement is often facilitated by proteins such as ion channels, pumps, and transporters to maintain the balance of hydrogen ions inside and outside the cell.
What structure in the plasma membrane regulate ion passage?
Ion channels and the hydrophilic/hydrophobic/hydrophilic membrane.
How do water molecules and small ions enter cells?
Some water molecules and small ions ( depending on charge, other ions need passive or active transport ) can diffuse across the cell's membrane and there are channels called porins that facilitate water molecule passage into the cell.
A protein channel in a hydrogen ion pump is shown below?
Protein channels in hydrogen ion pumps, such as the F0 portion of ATP synthase, facilitate the movement of hydrogen ions (protons) across a membrane. This movement creates an electrochemical gradient that is used to generate ATP in cellular respiration. The protein channel allows only hydrogen ions to pass through, maintaining the integrity of the membrane.
ATP synthases produce the force need to add one what to each ADP molecule by spinning when hydrogen ions flow through them?
The electron gradient created by the electron transport chain flows from the inner membrane space to the matrix through the ATP synthase which captures energy from the proton motive force to create lots of ATP in oxadative phosphorylation.
Do bases have a high or low concentration of hydrogen ions?
Bases have a lower concentration of hydrogen ions compared to acids. This is because bases donate hydroxide ions (OH-) which can combine with hydrogen ions (H+) to form water, reducing the concentration of free hydrogen ions in the solution.
An arrhenius acid has 1.only hydroxide ions in solution. 2.only hydrogen ions in solution. 3.hydrogen ions as the only positive ions in solution. 4.hydrogen ions as the only negative ions in solut?
An Arrhenius acid has only hydrogen ions in solution.
Does the pH scale indicate the consentration of hydrogen ions or hydroxide ions?
The pH scale indicates the concentration of hydrogen ions in a solution. A lower pH value indicates a higher concentration of hydrogen ions, while a higher pH value indicates a lower concentration of hydrogen ions.
