What characteristics do photosynthesis and cellular respiration have in common?
Both processes involve a cycle of chemical reactions. Both processes involve energy conversions. Both processes use and produce ATP. Both processes use an electron transport chain.
What is the relationship between photosynthesis and cellular respiration simple?
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 role does oxygen play in the electron transport chain quizlet?
What roles does oxygen play in photosynthesis and in cellular respiration? product, whereas cellular respiration uses oxygen as a reactant to release energy from food. The electron transport chain uses the energy stored in high energy electrons to pump H+ ions across the inner mitochondrial membrane.
What is the role of oxygen in the electron transport chain quizlet?
What is the role of oxygen in the electron transport chain? It is reduced to form water. During the energy investment phase of glycolysis, __________. Fermentation oxidizes NADH to NAD+, which facilitates the production of ATP in glycolysis.
What is the role of oxygen in electron transport system?
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. Oxygen sits at the end of the electron transport chain, where it accepts electrons and picks up protons to form water.
What is role of oxygen in the electron transport chain?
Oxygen plays a vital role in energy production via a system called electron transport chain (ETC), which is an important component of cellular respiration. Oxygen acts as a final electron acceptor that helps move electrons down a chain that results in adenosine triphosphate production.
What is the main purpose of the electron transport system?
Explanation: The electron transport chain is used to pump protons into the intermembrane space. This establishes a proton gradient, allowing protons to be pumped through ATP synthase in order to create ATP. This method of ATP production is called oxidative phosphorylation.
What is the electron transport chain and what is its function?
The electron transport chain is a series of electron transporters embedded in the inner mitochondrial membrane that shuttles electrons from NADH and FADH2 to molecular oxygen. In the process, protons are pumped from the mitochondrial matrix to the intermembrane space, and oxygen is reduced to form water.
