What is formed when enzymes move hydrogen ions across a membrane to an area of greater concentration?
A proton gradient is formed when enzymes transport hydrogen ions across a membrane, creating a difference in concentration between the two sides. This gradient can then be used to drive other cellular processes such as ATP production or transport of molecules across the membrane.
How many kj of energy will be released when the bonds in the two moles of water molecules are formed?
The energy released when the bonds of two moles of water molecules are formed is approximately 94 kJ. This energy is released because the bonds formed in water are stronger than the bonds broken in its constituent elements, hydrogen and oxygen.
Name two ions that are the products of the dissociation of water?
Another way to describe the dissociation of water is as follows where two water molecules form a hydronium ion (essentially a water molecule with a proton attached) and a hydroxide ion
How does the phosphate buffer system help in maintaining the pH of our body?
The phosphate buffer system consists of two ions: dihydrogen phosphate ions and hydrogen phosphate ions. When the number of hydrogen ions in a body's bloodstream increases (pH drops), hydrogen phosphate ions accept hydrogen ions in order to maintain the equilibrium between the concentration of hydrogen and hydroxide ions within the bloodstream. When the number of hydrogen ions in the bloodstream decreases (pH increases), the resulting dihydrogen phosphate ions release hydrogen ions in order to increase the number of hydrogen ions in the blood.
What is a relatively weak bond between polar molecules?
A hydrogen bond is a relatively weak bond formed between polar molecules. It occurs between a hydrogen atom bonded to an electronegative atom (such as nitrogen, oxygen, or fluorine) and another electronegative atom in a different molecule.
Which bond type is formed between two polar molecules that contain hydrogen?
a hydrogen bond
When two water molecules react what do they create?
Two water molecules can react to from hydrogen bonds. If one water molecule acts as an acid and donates a proton to another water molecule then hydronium ions an hydroxyl ions can be formed as well.
Does hydrogen have oxygen?
No, hydrogen and oxygen are two separate elements. Hydrogen is a chemical element that exists as H2 molecules, while oxygen exists as O2 molecules. Water (H2O) is formed when hydrogen combines with oxygen.
What two hydrogen carrying molecules are formed during the Krebs cycle?
The two high energy molecules that are produced in the Krebs Cycles are NADH and FADH2. :D
What is formed when enzymes move hydrogen ions across a membrane to an area of greater concentration?
A proton gradient is formed when enzymes transport hydrogen ions across a membrane, creating a difference in concentration between the two sides. This gradient can then be used to drive other cellular processes such as ATP production or transport of molecules across the membrane.
What are two things produced by neutralization?
Two things produced by neutralization are water and a salt. Water is formed as a result of the reaction between the hydrogen ions from an acid and the hydroxide ions from a base. A salt, which is an ionic compound, is formed when the positive ions from the base combine with the negative ions from the acid.
How is h20 formed?
Water (H2O) is formed through a chemical reaction between two hydrogen atoms and one oxygen atom that combines to create a water molecule. This process occurs when two hydrogen molecules react with one oxygen molecule to form two water molecules.
How are molecules different than ions or atoms?
Molecules are formed when two or more atoms chemically bond together, while atoms are the smallest unit of matter that retains the properties of an element. Ions are atoms or molecules that have gained or lost electrons, resulting in a positive or negative charge, respectively.
What type of bond is formed between two water molecule?
the bond between two water molecule is hydrogen bond.
What are particles that make up a compound called?
The particles that make up a compound are called molecules or ions. Molecules are formed when two or more atoms chemically bond together, while ions are formed when atoms gain or lose electrons to achieve a stable electronic configuration.
How many ions in hydrogen iodide?
Two ions: H+ and I-
How an ionic compound forms free ions in water?
like an ionic charge? i think your refereing to hydrogen bonds formed between two water molecules. this occurs when the oxogen (6 electrons) and 2 hydrogens (1 electron) are covelantly bonded. when they bond, it is polar (a polar covalent bond) which means that electrons are unequally distributed (oxogen give an extra electron to each of the hydrogen) leaving the water molecule charge oppositely at each end. oxogen = - charge/ hydrogen = + charge. so the molecules work as a magnet, making weak bonds between each other.
