Answer:
This would be the MITOCHONDRIA!
<em>Concept(s):</em>
- Mitochondria
- An organelle in the cytoplasm of cells that functions in energy production.
- Organelle
- A specialized [art pf a cell having some specific function; a cell organ.
- Krebs's cycle
- A cycle of enzyme-catalyzed reactions in living cells that is the final series of reactions of aerobic metabolism of carbohydrates, proteins, and fatty acids, and by which carbon dioxide is produced, oxygen is reduced, and ATP is formed.
- Electron
- An elementary particle that is a fundamental constituent of matter, having a negative charge of 1.602 × 10-19 coulombs, a mass of 9.108 × 10-31 kilograms, and spin of 1/2. and existing independently or as the component outside the nucleus of an atom.
Explanation:
<em>In what organelle do both the Krebs cycle and the electron transport system occur?</em>
<em>Mitochondrion</em>
The mitochondria's sole function is to provide the cell with energy, and the only way it can do this is by drawing its power from the ATP molecules created by the Krebs cycle and the electron transport system.
<em>What is the significance of an electron transport chain? Like the energy is already produced in Krebs cycle, so why does the Electron transport chain run?</em>
The chemical processes fueled by enzymes are known as the Kreb's cycle. Since these processes need certain enzymes, they happen inside the mitochondria. 32 molecules of ATP are produced by the Kreb's cycle for every molecule of glucose, Carbon IV oxide, and hydrogen ions.
In the hydrogen ion transport chain, hydrogen ions can enter through a variety of acceptor molecules, such as NAD (nicotinamide adenine), which produces NADH2. Their hydrogen is taken up by oxygen to create water, which releases energy. ADP uses this energy to create ATP.
<em>How does the Krebs cycle and electron transport chain work?</em>
A closed loop is the Krebs or citric acid cycle. The substance utilized in the first step is renewed in the pathway's final stage. In each of the cycle's eight phases, redox, dehydration, hydration, and decarboxylation processes result in the production of two carbon dioxide molecules, one GTP/ATP molecule, and reduced forms of NADH and FADH.
Electron transport is a sequence of redox events where electrons are quickly transferred from one component to the next until they reach the end of the chain where they reduce molecule oxygen to produce water. These redox reactions resemble a relay race or bucket brigade.
The electron transport chain, a sequence of electron transporters that are involved in redox processes, is the source of the majority of the ATP produced during the aerobic catabolism of glucose. As a result, hydrogen ions start to build up in the matrix space. As a result, a concentration gradient develops, allowing hydrogen ions to migrate through ATP synthase and out of the matrix region. The catalytic activity of ATP synthase, which phosphorylates ADP to produce ATP, is driven by the current of hydrogen ions.
