What is the electron transport chain for kids?
From Academic Kids The electron transfer chain (also called the electron transport chain, ETC, e-train, or simply electron transport), is any series of protein complexes and lipid-soluable messengers that convert the reductive potential of energized electrons into a cross-membrane proton gradient.
What is the electron transport chain in simple terms?
The electron transport chain is a cluster of proteins that transfer electrons through a membrane within mitochondria to form a gradient of protons that drives the creation of adenosine triphosphate (ATP). ATP is used by the cell as the energy for metabolic processes for cellular functions.
What are the 4 steps of the electron transport chain?
The complete cellular process consists of four pathways: glycolysis, pyruvate oxidation, the Krebs cycle, and oxidative phosphorylation.
How do you remember the electron transport chain?

So imagine brother nad and fad cooked for 42 dishes with water and ATP.
What are the 5 steps of the electron transport chain?
The key steps of this process, shown in simplified form in the diagram above, include:
- Delivery of electrons by NADH and FADH 2start subscript, 2, end subscript. …
- Electron transfer and proton pumping. …
- Splitting of oxygen to form water. …
- Gradient-driven synthesis of ATP.
What are the 3 main steps in the electron transport chain?
The three main steps in the electron transport chain are:
- Generation of a proton gradient across the mitochondrial membrane. Proton accumulation occurs in the intermembrane space of mitochondria.
- Reduction of molecular oxygen and formation of water. …
- ATP synthesis by chemiosmosis.
What happens in the electron transport chain?
In the electron transport chain, electrons are passed from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient. In chemiosmosis, the energy stored in the gradient is used to make ATP.
What is the role of electron transport chain?
Explanation: The electron transport chain is primarily used to send protons across the membrane into the intermembrane space. This create a proton-motive force, which will drive ATP synthase in the final step of cellular respiration to create ATP from ADP and a phosphate group.

What are the 5 components of the electron transport chain?
The components of the chain include FMN, Fe–S centers, coenzyme Q, and a series of cytochromes (b, c1, c, and aa3). The energy derived from the transfer of electrons through the electron transport chain is used to pump protons across the inner mitochondrial membrane from the matrix to the cytosolic side.
What happens in electron transport chain?
In the electron transport chain, electrons are passed from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient. In chemiosmosis, the energy stored in the gradient is used to make ATP.
What is the main function of the electron transport chain?
The main function of the electron transport chain is to generate an electrochemical gradient, which drives the synthesis of ATP during cellular respiration and photosynthesis in mitochondria and chloroplasts, respectively.
What is the role of the electron transport chain?
The electron transport chain is primarily used to send protons across the membrane into the intermembrane space. This create a proton-motive force, which will drive ATP synthase in the final step of cellular respiration to create ATP from ADP and a phosphate group.
Why is electron transport chain important?
The ETC is the most important stage of cellular respiration from an energy point of view because it produces the most ATP. In a series of redox reactions, energy is liberated and used to attach a third phosphate group to adenosine diphosphate to create ATP with three phosphate groups.
What is the electron transport chain also known as?
The respiratory chain, otherwise known as the electron transport chain, resides in the mitochondria. A single molecule of NADH has sufficient energy to generate three ATP molecules from ADP.
What is the function of electron transport chain?
The main function of the electron transport chain is to generate an electrochemical gradient, which drives the synthesis of ATP during cellular respiration and photosynthesis in mitochondria and chloroplasts, respectively.
What is an example of electron transport chain?
Electrons may enter an electron transport chain at the level of a mobile cytochrome or quinone carrier. For example, electrons from inorganic electron donors (nitrite, ferrous iron, electron transport chain) enter the electron transport chain at the cytochrome level.
How does electron transport chain work?
In the electron transport chain, electrons are passed from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient. In chemiosmosis, the energy stored in the gradient is used to make ATP.
Where is electron transport chain located?
inner mitochondrial membrane Since the electron transport chain is located in the inner mitochondrial membrane in eukaryotes, and since NADH cannot be transported from the cytosol into the mitochondrial matrix, NADH formed in the cytosol needs to be oxidized by another route.
What is electron transport chain made of?
The electron transport chain is composed of four large, multiprotein complexes embedded in the inner mitochondrial membrane and two small diffusible electron carriers shuttling electrons between them.
What do electron transport chains do?
The electron transport chain is a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation. It occurs in mitochondria in both cellular respiration and photosynthesis.
What happens in an electron transport chain?
In the electron transport chain, electrons are passed from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient. In chemiosmosis, the energy stored in the gradient is used to make ATP.
What is the main purpose of the electron transport chain?
The primary task of the last stage of cellular respiration, the electron transport chain, is to transfer energy from the electron carriers to even more ATP molecules, the "batteries" which power work within the cell.
What is the electron transport chain made up of?
The electron transport chain is composed of four large, multiprotein complexes embedded in the inner mitochondrial membrane and two small diffusible electron carriers shuttling electrons between them.
