What component cellular respiration carries the energy from the reduced molecule to the oxidized molecule?
In cellular respiration, the component that carries energy from the reduced molecule (such as glucose) to the oxidized molecule (like oxygen) is the electron transport chain (ETC). The ETC consists of a series of protein complexes and electron carriers that transfer electrons derived from reduced coenzymes (NADH and FADH2) generated during earlier stages of respiration. As electrons move through the chain, their energy is used to pump protons across the mitochondrial membrane, creating a proton gradient that ultimately drives ATP synthesis.

What is light energy and what does it do for cellular respiration?
Light energy does not affect respiration, but it is needed for photosynthesis, which in plants creates the chemical compounds (carbohydrates) that are oxidized in cellular respiration.
Where a molecule gives up electrons and releases energy?
This process occurs during oxidation, where a molecule loses electrons and energy is released. Oxidation reactions are important in cellular respiration, where glucose is oxidized to release energy for the cell to use.
What is one true distinction between fermentation and cellular respiration?
cellular respiration uses oxygen but fermentation does not use oxygen
How many ATP are made in aerobic cellular respiration?
Glycolysis is a 10 step enzymatically catalyzed reaction which splits up a glucose molecule into two molecules of pyruvate. The process of glycolysis can occur in absence of oxygen. A net yield of 2 ATP is obtained at the end of gylcolysis for every molecule of glucose oxidized.
Which one of the reactant for cellular respiration gets oxidized and which one gets reduced?
During cellular respiration, glucose gets oxidized to form carbon dioxide and water, while oxygen gets reduced to form water. Glucose loses electrons and hydrogen atoms, which are transferred to oxygen during the process, resulting in the reduction of oxygen to water.
What oxidized during cellular respiration?
Glucose is. In cell respiration, the carbon atoms of glucose are oxidized.
What is oxidized in aerobic cellular respiration?
glucose
Is NAD reduced or oxidized during cellular respiration?
NAD is reduced during cellular respiration.
What is oxidized during the oxidation stage of cellular respiration?
Glucose is. In cell respiration, the carbon atoms of glucose are oxidized.
Is NAD reduced or oxidized to NADH during cellular respiration?
NAD is reduced to NADH during cellular respiration.
Is NADH reduced to NAD during cellular respiration?
Yes, NADH is oxidized to NAD during cellular respiration.
During cellular respiration, how is the substrate both oxidized and reduced?
During cellular respiration, the substrate is oxidized by losing electrons and reduced by gaining electrons in a series of redox reactions.
What substance is oxidized during cellular respiration?
Glucose is the primary substance that is oxidized during cellular respiration. It is broken down in a series of metabolic reactions to produce ATP, the energy currency of cells, through the process of oxidation.
What is light energy and what does it do for cellular respiration?
Light energy does not affect respiration, but it is needed for photosynthesis, which in plants creates the chemical compounds (carbohydrates) that are oxidized in cellular respiration.
Is glucose oxidized or reduced in cellular respiration?
Glucose is oxidized in cellular respiration to produce energy in the form of ATP. During the process, glucose is broken down into carbon dioxide and water, releasing electrons that are used in the electron transport chain to generate ATP.
What is one true distinction between fermentation and cellular respiration?
cellular respiration uses oxygen but fermentation does not use oxygen
Where a molecule gives up electrons and releases energy?
This process occurs during oxidation, where a molecule loses electrons and energy is released. Oxidation reactions are important in cellular respiration, where glucose is oxidized to release energy for the cell to use.
