What is the role of the electron transport chain in cellular respiration quizlet?
What is the function of the electron transport chain in cellular respiration? The electron transport chain shuttles electrons down a series of redox reactions that release energy used to make ATP.
What is the main role of electron transport system in photosynthesis and cellular respiration?
Photosynthesis uses the energy obtained from light to free electrons from the chlorophyll pigments that collect the light. In cellular respiration the electron transport chain occurs after glucose has already been broken down.
What are the main 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 are the similarities and differences of photosynthesis and cellular respiration?
Some differences between photosynthesis and respiration are that photosynthesis only happens in sunlight while respiration happens constantly and that photosynthesis releases oxygen while respiration uses it. Some similarities between the two are that both produce energy and involve the exchange of gases.
What is the difference between Chemiosmosis in photosynthesis and cellular respiration?
Both cellular respiration and photosynthesis use chemiosmosis to create ATP. Chemiosmosis refers to specific steps within the electron transport chain utilized to create ATP. In cellular respiration, food is converted into ATP, while photosynthesis uses light energy to release ATP.
What is the main function of the electron transport chain?
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 is the primary function of the 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 is the electron transport chain also known as?
The respiratory chain, otherwise known as the electron transport chain, resides in the mitochondria. The chain consists of a series of electron carriers which can accept and then donate electrons, while the resulting production of energy is used to stimulate the formation of ATP via oxidative phosphorylation.
What is the connection between photosynthesis and cellular respiration?
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
What is the purpose of electron transport chain in the cell?
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 electrons passed from during electron transport chain?
The electron transport chain is a series of protein complexes and electron carrier molecules within the inner membrane of mitochondria that generate ATP for energy. Electrons are passed along the chain from protein complex to protein complex until they are donated to oxygen. During the passage of electrons, protons are pumped out of the mitochondrial matrix across the inner membrane and into the intermembrane space.
Where in the cell does the electron transport occur?
In prokaryotic cells, those of bacteria and bacteria-like Archaeans, electron transport takes place in the cell’s plasma membrane , in folded areas called mesosomes. For most organisms, this conversion is accomplished though cellular respiration, a series of biochemical pathways in which glucose (a sugar ) is broken down and the energy extracted is converted to ATP.
What is the function of the electron transport?
The function of the electron transport chain is to produce a transmembrane proton electrochemical gradient as a result of the redox reactions.
