Reducing agent A molecule that can donate electrons. A reducing agent reduces the molecule that it donates electrons to. RuBisCo Ribulose-1,5-bisphosphate carboxylase oxygenase, or the enzyme used in the light-independent reactions to fix carbon dioxide 2
Following glycolysis, the mechanism of cellular respiration then involves another multistep process called the Krebs cycle, also called the citric acid cycle and the tricarboxylic acid cycle. The Krebs cycle uses the two molecules of pyruvic acid formed in glycolysis and yields high-energy molecules of NADH and FADH and some ATP and carbon dioxide (Figure 1 ).
Carbon Tax: Definition, How It Works, Pros, Cons
2020/8/1· A carbon tax is a fee that a government imposes on any company that burns fossil fuels. The most widely-discussed are coal, oil, gasoline, and natural gas. When these carbon-rich fuels are burned, they produce greenhouse gases. These gases, such as carbon

Carbohydrates - Michigan State University
As noted above, sugars may be classified as reducing or non-reducing based on their reactivity with Tollens'', Benedict''s or Fehling''s reagents. If a sugar is oxidized by these reagents it is called reducing , since the oxidant (Ag (+) or Cu (+2) ) is reduced in the reaction, as evidenced by formation of a silver mirror or precipitation of cuprous oxide.
