In redox reactions, "reduced" refers to the gain of electrons by a species. When a substance is reduced, its oxidation state decreases, indicating that it has accepted electrons from another substance that is being oxidized (which loses electrons). This transfer of electrons is fundamental to redox processes, playing a crucial role in energy transfer, chemical reactivity, and various biological functions.

Which 3 types of reactions are ALWAYS redox reactions?
Redox reactions are divided into two main types.(i) Inter molecular Redox:In such redox reactions, one molecule of reactant is oxidized whereas molecule of other reactant is reduced.(ii)Intra molecular Redox:One atom of a molecule is oxidized and other atom of same molecule is reduced then it is intramolecular redox reaction.e.g., 2Mn2O7 4MnO2 + 3O2.
Is glycolysis a redox reactions?
Glycolysis involves a series of enzymatic reactions that convert glucose into pyruvate, and it does include redox reactions. Specifically, during the conversion of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate, NAD+ is reduced to NADH, which is a key redox reaction in the pathway. However, glycolysis as a whole is not solely defined by redox reactions; it also includes non-redox steps that involve substrate-level phosphorylation and isomerization.
What is reddox reactions?
Redox reactions, short for reduction-oxidation reactions, involve the transfer of electrons between reactants. In these reactions, one substance gets oxidized (loses electrons) while another gets reduced (gains electrons). Redox reactions are important in various chemical processes, such as combustion, corrosion, and metabolism.
What coenzyme is used to carry electrons in redox reactions?
A coenzyme called NAD is used to carry electrons in different kinds of redox reactions. NAD stands for nicotinamide adenine dinucleotide.
Where does Redox occur in bacteria?
The Redox 'Battlefield' is the Redox reactions mediated by bacteria.

Photosynthesis is a redox reaction. This means that H2O is BLANK during the light reactions and CO2 is BLANK during the Calvin cycle. a. consumed...reduced b. reduced...oxidized c. oxidized...reduced?
Photosynthesis is a redox reaction where water (H2O) is oxidized during the light reactions, leading to the release of oxygen as a byproduct. In the Calvin cycle, carbon dioxide (CO2) is reduced to form carbohydrates with the help of ATP and NADPH produced during the light reactions. Therefore, the correct options are c. oxidized...reduced.
What coenzyme is used to carry electrons in redox reactions?
A coenzyme called NAD is used to carry electrons in different kinds of redox reactions. NAD stands for nicotinamide adenine dinucleotide.

Are all combustion reactions redox processes?
Yes, all combustion reactions are redox processes.
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.
Is cu hno3 redox?
Copper(II) nitrate (Cu(NO3)2) itself is not a redox substance, as it does not undergo a change in oxidation states during typical reactions. However, in reactions involving copper compounds, such as when Cu(NO3)2 reacts with reducing agents, redox processes can occur. In those cases, copper may be reduced or oxidized, depending on the specific reactants involved. Thus, while Cu(NO3)2 can participate in redox reactions, it is not inherently a redox agent by itself.
Explain in general terms how redox reactions are involved in energy exchanges?
Redox reactions involve the transfer of electrons between species. When a substance is oxidized, it loses electrons, and when it is reduced, it gains electrons. These electron transfers are often associated with the release or absorption of energy, making redox reactions important in energy exchanges within biological systems such as cellular respiration and photosynthesis.
Are single displacement and double displacement reactions always redox reactions?
No, single displacement and double displacement reactions are not always redox reactions. Redox reactions involve electron transfer between reactants, while single displacement and double displacement reactions do not always involve the transfer of electrons.
What is the difference between NADP and NADPH in terms of their roles in cellular metabolism and redox reactions?
NADP and NADPH are both coenzymes involved in redox reactions in cellular metabolism. NADP primarily functions in anabolic reactions, such as biosynthesis, while NADPH is the reduced form of NADP and serves as a key electron carrier in these reactions. NADPH is essential for processes like fatty acid and nucleotide synthesis, while NADP is more involved in maintaining cellular redox balance.
