What happens to NADH in the electron transport chain?
The events of the electron transport chain involve NADH and FADH, which act as electron transporters as they flow through the inner membrane space. In complex I, electrons are passed from NADH to the electron transport chain, where they flow through the remaining complexes. NADH is oxidized to NAD in this process.
How many electrons does NADH carry?
two electrons
Yet each NADH donates two electrons, and each O2 molecule must receive four electrons to produce water.
What drives the H+ to leave the thylakoid space?
To replace the electron in the reaction center, a molecule of water is split. As the electron passes along these proteins, energy from the electron fuels membrane pumps that actively move hydrogen ions against their concentration gradient from the stroma into the thylakoid space.
How are pH and H+ related?
The pH value of a substance is directly related to the ratio of hydrogen ion [H+] and hydroxyl ion [OH-] concentrations. If the H+ concentration is greater than the OH-, the material is acidic; i.e., the pH value is less than 7.
Are H and OH conjugate acid base pairs?
HCl is a strong acid. When it donates a proton, a Cl– ion is produced, and so Cl– is the conjugate base. CH3NH2 is an amine and therefore a weak base. Adding a proton to the strong base OH– gives H2O its conjugate acid.
What is the reaction between HCl and h2o?
Upon contact, H2O and HCl combine to form hydronium cations H3O+ and chloride anions Cl− through a reversible chemical reaction: HCl + H2O → H3O+ + Cl. The resulting solution is called hydrochloric acid and is a strong acid.
What does oxygen get reduced to at the end of the electron transport chain?
water
Figure 1. The electron transport chain is a series of electron transporters embedded in the inner mitochondrial membrane that shuttles electrons from NADH and FADH2 to molecular oxygen. In the process, protons are pumped from the mitochondrial matrix to the intermembrane space, and oxygen is reduced to form water.
Is NADH an electron carrier?
NADH is the reduced form of the electron carrier, and NADH is converted into NAD+. This half of the reaction results in the oxidation of the electron carrier.
What are the 3 electron carriers?
Examples of Electron Carriers
- Flavin Adenine Dinucleotide. Flavin adenine dinucleotide, or FAD, consists of riboflavin attached to an adenosine diphosphate molecule.
- Nicotinamide Adenine Dinucleotide.
- Coenzyme Q.
- Cytochrome C.
How does NADP+ become NADPH H+?
The two reactions use carrier molecules to transport the energy from one to the other. The lower energy form, NADP+, picks up a high energy electron and a proton and is converted to NADPH. When NADPH gives up its electron, it is converted back to NADP+.

What role do hydrogen ions H +) play in the electron transport chain?
What role do hydrogen ions (H+) play in the electron transport chain? They are pumped across the mitochondrial inner membrane against their concentration gradient (to where their concentration is high); as the H+ ions flow back to where their concentrations are low, they drive ATP synthase to form ATP.
When hydrogen ions H +) are pumped across the inner mitochondrial membrane they form a proton gradient ATP is then formed by a process called?
Electrons are passed from one member of the transport chain to another in a series of redox reactions. Energy released in these reactions is captured as a proton gradient, which is then used to make ATP in a process called chemiosmosis.
What happens when H+ Leave the thylakoid space?
High-energy electrons leave the chlorophyll and enter an electron transport chain, which is a series of proteins in the membrane of the thylakoid. 2 Water molecules split Enzymes break down water molecules. hydrogen ions (H+), and electrons are separated from each other. The oxygen is released as waste.
At the end of the pathway, the electrons are used to reduce an oxygen molecule to oxygen ions. The extra electrons on the oxygen attract hydrogen ions (protons) from the surrounding medium, and water is formed.
Which process will be halted when the inner mitochondrial membrane becomes leaky to H+?
A proton gradient can no longer be formed across the inner mitochondrial membrane as pumping of hydrogen ion is stopped. This will result in the decrease of pH across the inner membrane of mitochondria and increase of pH in the intracellular region.
How does Chemiosmosis work?
Chemiosmosis is the movement of ions across a semipermeable membrane bound structure, down their electrochemical gradient. An example of this would be the formation of adenosine triphosphate (ATP) by the movement of hydrogen ions (H+) across a membrane during cellular respiration or photosynthesis.
How are 32 ATP produced?
The NADH pulls the enzyme’s electrons to send through the electron transport chain. The electron transport chain pulls H+ ions through the chain. From the electron transport chain, the released hydrogen ions make ADP for an end result of 32 ATP.
In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water. The lower energy form, NADP+, picks up a high energy electron and a proton and is converted to NADPH.
Does more H+ mean higher pH?
High concentrations of hydrogen ions yield a low pH (acidic substances), whereas low levels of hydrogen ions result in a high pH (basic substances). Therefore, the more hydrogen ions present, the lower the pH; conversely, the fewer hydrogen ions, the higher the pH.
Why is pH used instead of H+?
Originally Answered: Why is the pH scale used only for determining the concentration of H+ ions? Because that is what pH is defined as. The pH is the negative logarithm of the hydrogen ion concentration. You can also have pOH.
What is the relationship between ETC and oxygen?
Explanation: Oxygen acts as the terminal electron acceptor in the electron transport chain (ETC). This accounts for the reason as to why, when cells are starved of oxygen, the ETC “backs up” and the cell will divert to using anaerobic respiration, such as fermentation.
Is CO2 an electron donor or acceptor?
2-, NO3 -, or CO2 is the final electron acceptor. maintaining balanced amounts of oxidants and reductants necessary for diverse metabolic processes.
Why is NADH an electron carrier?
The nitrogenous base in NADH has one more hydrogen ion and two more electrons than in NAD+. NAD+ is used by the cell to “pull” electrons off of compounds and to “carry” them to other locations within the cell; thus it is called an electron carrier.
Is NADP+ an electron carrier?
NADP+/NADPH uses its electrons to build things that are involved in anabolic or biosynthetic pathways. NADP+ is an electron carrier that can reduce other molecules in biosynthetic reactions. In biological systems, the more reduced a molecule, the more potential it has to yield energy when it’s broken down.
Which has the highest H+ concentration?
Lemon juice has the highest h+ concentration. The more acidic something is the more H+ it has. ph = 14 is the most basic (opposite of acidic…
How is Chemiosmosis achieved?
Chemiosmosis: In oxidative phosphorylation, the hydrogen ion gradient formed by the electron transport chain is used by ATP synthase to form ATP. The turning of this molecular machine harnesses the potential energy stored in the hydrogen ion gradient to add a phosphate to ADP, forming ATP.
