What else can I help you with?
The reactions that convert the energy in sunlight into chemical energy of ATP and NADPH?
The reactions that convert the energy in sunlight into chemical energy of ATP and NADPH are called the light-dependent reactions of photosynthesis. These reactions occur in the thylakoid membranes of chloroplasts and involve the absorption of light by chlorophyll and other pigments to drive the production of ATP and NADPH through a series of electron transport chain reactions.
Where in the cell do electron transport chain occur?
In the mitochondria. The complexes need for the electron transport chain are attached on the inner side of the inner mitochondrial membrane, which channels opening into the intermembrane space for pumping out protons.
Where does a Electron Transport Chain happen?
In aerobic respiration, electron transport occurs inside the mitochondria. In photosynthesis, electron transport occurs inside the chloroplasts.
What happens if the hydrogen pumps in photo systems i and ii and not working correctly?
If the hydrogen pumps in photosystems I and II are not working correctly, there will be a disruption in the electron transport chain of photosynthesis. This will lead to a decrease in the production of ATP and NADPH, which are necessary for the light-dependent reactions to occur. As a result, the overall process of photosynthesis will be impaired, leading to reduced plant growth and metabolism.
What goes into the electron transport chain?
In the electron transport chain, electrons are transferred through a series of protein complexes embedded in the inner mitochondrial membrane. These protein complexes, labeled I to IV, use the energy from electron transport to pump protons across the membrane, creating an electrochemical gradient. The energy from this gradient is then used by ATP synthase to generate ATP.
Which reactions of aerobic respiration occur in the inner mitochondrial membranes?
The electron transport chain and oxidative phosphorylation occur in the inner mitochondrial membrane of cells during aerobic respiration. These processes involve transferring electrons through a series of protein complexes to generate ATP, the cell's primary energy source. The inner mitochondrial membrane provides a specialized environment for these reactions to occur efficiently.
What does electron transport chain occur in?
the mitochondria.
What reactions occur in the cristae of the mitochondria?
The cristae of the mitochondria are the sites for the electron transport chain and oxidative phosphorylation. These reactions involve transferring electrons along the chain and using the energy released to pump protons across the inner mitochondrial membrane, creating a proton gradient that drives ATP synthesis.
Does the light independent reactions of the Calvin cycle occur in the thylakoids?
In photosynthesis, the the electron transport chain is part of the light dependent reactions. The "light independent reactions" are the Calvin-Benson cycle and do not include an electron transport chain, but the Calvin Cycle cannot proceed without the ATP and NADPH produced during the light reactions.
Where do the reactions of the electron transportation chain occur?
In the inner membrane of the mitochondria.
Where does cyclic electron transport occur?
Cyclic electron transport occurs in the thylakoid membrane of chloroplasts during the light reactions of photosynthesis. It involves the flow of electrons through the photosynthetic electron transport chain to generate ATP without the production of NADPH.
Where do the reactants of the electron transport chain occur?
In the inner membrane of the mitochondrial organelle.
Can the electron transport chain occur without the Krebs cycle?
Yes, the electron transport chain can occur without the Krebs cycle. The electron transport chain generates ATP by transferring electrons through a series of protein complexes in the inner mitochondrial membrane, regardless of whether the electrons come from the Krebs cycle or other sources.
Where do the reactions of the election transport chain occur?
The reactions of the electron transport chain (ETC) occur in the inner mitochondrial membrane of eukaryotic cells. This membrane houses the protein complexes and electron carriers that facilitate the transfer of electrons from NADH and FADH2 to oxygen. As electrons move through the chain, protons are pumped into the intermembrane space, creating a proton gradient that drives ATP synthesis through ATP synthase. In prokaryotes, the ETC occurs in the cell membrane since they lack mitochondria.
Where in the cell does the electron transport occur?
The electron transport chain occurs in the inner mitochondrial membrane. This is where electron carriers in the membrane transport electrons and pump protons to generate ATP through oxidative phosphorylation.
What are the three processes that occur during cell respiration?
The three processes that occur during cell respiration are glycolysis, the citric acid cycle (Krebs cycle), and oxidative phosphorylation (electron transport chain). Glycolysis breaks down glucose into pyruvate, the citric acid cycle further breaks down pyruvate to produce ATP and electron carriers, and oxidative phosphorylation uses these electron carriers to generate most of the ATP through a series of redox reactions.
Why is the electron transport chain aerobic and not anaerobic?
The electron transport chain is aerobic because it requires oxygen to function. Oxygen is the final electron acceptor in the chain, allowing for the production of ATP through oxidative phosphorylation. In contrast, anaerobic processes do not require oxygen and can occur in the absence of oxygen.
