What are the inputs of oxidative phosphorylation?
Oxidative phosphorylation is the process by which ATP is synthesised when electrons are transported from the energy precursors produced in the citric acid cycle through various enzyme complexes to molecular oxygen. The input is NADH, FADH2, O2 and ADP. The output is NAD+, FAD+, H2O and ATP.
What are the reactants for oxidative phosphorylation?
| Glycolysis | Oxidative Phosphorylation | |
|---|---|---|
| Reactants | Glucose 2 ATP 2 NAD+ | 8 NADH 4 FADH2 6 O2 |
| Products | 2 pyruvate 4 ATP 2 NADH | 8 NAD+ 4 FAD+ 32 ATP 6 H2O |
| ATP required | 2 | None |
| ATP produced | 4 | 32 |
What are the starting ingredients of oxidative phosphorylation?
The three major steps in oxidative phosphorylation are (a) oxidation-reduction reactions involving electron transfers between specialized proteins embedded in the inner mitochondrial membrane; (b) the generation of a proton (H+) gradient across the inner mitochondrial membrane (which occurs simultaneously with step (a …
What are the reactants and products of the ETC?
| Quiz: What are the initial reactants which start the electron transport chain? | Answer 2 hydrogen ions and 2 electrons start the chain. Oxygen and ADP are also reactants. |
|---|---|
| What are the final products of the chain? | Answer 3 ATP and a water molecule are products. |
What supplies the electrons for oxidative phosphorylation?
In oxidative phosphorylation, oxygen must be present to receive electrons from the protein complexes. This allows for more electrons and high energy molecules to be passed along, and maintains the hydrogen pumping that produces ATP.
Where does oxidative phosphorylation occur?
Oxidative phosphorylation occurs in the mitochondria of all animal and plant tissues, and is a coupled process between the oxidation of substrates and production of ATP. As the Kreb’s cycle runs, hydrogen ions (or electrons) are carried by the two carrier molecules NAD or FAD to the electron transport pumps.
What is the byproduct of oxidative phosphorylation?
The energy stored in the chemical bonds of glucose is released by the cell in the citric acid cycle producing carbon dioxide, and the energetic electron donors NADH and FADH. Oxidative phosphorylation uses these molecules and O2 to produce ATP, which is used throughout the cell whenever energy is needed.
Which of the following is a product of oxidative phosphorylation?
So, the correct answer is, ‘ATP+H2O.
What are the inputs of glycolysis?
Glycolysis is the first step in cellular respiration, occurring in all living cells. Overall, the input for glycolysis is one glucose, two ATP and two NAD+ molecules giving rise to two pyruvate molecules, four ATP and two NADH.
What are the inputs and outputs of the electron transport chain?
A good estimate is about 2-3 ATP per NADH and 1.5 ATP per FADH2. A very efficient cell can produce a total of 38 ATP from a single glucose molecule….The Electron Transport Chain: Mass-Producing ATP.
| Process | Electron Transport Chain (ETC) |
|---|---|
| Location | Mitochondria (Inner Membrane) |
| Input | 6 NADH 2 FADH2 |
| Output | 6H2O 34(ish) ATP |
Which molecules are 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.
Where does etc take place in mitochondria?
inner membrane
The electron transport chain activity takes place in the inner membrane and the space between the inner and outer membrane, called the intermembrane space.
