Which protein complex allows hydrogen ions to rush out of the thylacoid providing energy that can be used to make a molecule?
ATP synthase is the protein complex that allows hydrogen ions to flow out of the thylakoid membrane during photosynthesis. This flow of hydrogen ions creates a proton gradient that drives the production of ATP, which is a molecule that stores energy for the cell to use.
What must the membrane protein do so that hydrogen ions can flow through it?
To allow hydrogen ions to flow through a membrane protein, the protein must form a channel or pore that selectively permits the passage of these ions. This often involves conformational changes in the protein structure that create a pathway through the lipid bilayer. Additionally, the protein may utilize mechanisms like facilitated diffusion or active transport, depending on the concentration gradient and energy requirements. Proper orientation and charge properties of the protein's interior are also crucial for the selective transport of hydrogen ions.
Hydrogen ions flow back into the inner compartment through?
ATP synthase, a protein complex embedded in the inner mitochondrial membrane. This process is known as chemiosmosis and drives the synthesis of ATP from ADP and inorganic phosphate.
What base produces few ions?

Why protein solution turns purple when copper sulfate solution is added?
Copper sulfate solution provides cupric ions that react with the peptide bonds present in the protein molecule. The test is called as biuret test, as it was originally given by biuret compound.( when urea is heated it forms biuret). The reaction is due to the formation of complex between the cupric ions and lone pair of electrons present on the Nitrogen and Oxygen atoms of peptide bond.
Does a acid produce oh-ions?
acid produces H+ ions base produces OH- ions
What is the complex formed between Cu2 plus and protein in biuret test?
In the biuret test, the complex formed between Cu2+ and protein is a coordination complex where the peptide bonds in the protein act as ligands to chelate with the Cu2+ ions. This complexation causes a color change, typically from blue to violet or purple, indicating the presence of proteins in the sample.
Which type of cell transport is used by mitochondria to generate energy by allowing hydrogen (H ) ions to flow through a membrane protein?
Mitochondria utilize facilitated diffusion to generate energy by allowing hydrogen ions (H⁺) to flow through a membrane protein known as ATP synthase. This process occurs during oxidative phosphorylation, where the flow of H⁺ ions down their concentration gradient drives the synthesis of ATP from ADP and inorganic phosphate. The movement of these ions is aided by the electrochemical gradient established by the electron transport chain.
What is the definition of protein gate?
A protein gate is a pathway through a protein molecule on the plasma membrane in which ions and small molecules can diffuse in or out of a cell.
Ions may be described as simple or complex?
In chemistry are known simple ions but also complex ions.
Are ligands complex ions?
No, ligands are not complex ions. Ligands are molecules or ions that can donate electrons to form coordinate bonds with a central metal ion to create a coordination complex. In contrast, complex ions are ions formed from a central metal ion bonded to surrounding ligands.
Is there metal in blood?
In the blood of vertebrates and some invertebrates iron ions bound in a protein complex called hemoglobin transports oxygen. In the blood of many invertebrates copper ions bound in a protein complex called hemocyanin transports oxygen. However it is very likely that unbound sodium ions in the blood plasma outnumber the iron ions or copper ions in either case.
