(b) If the specific activity of the glucose substrate is 10 mCi mM-1, what is the specific activity of the pyruvate that is formed? Answer: (a) The label is in the methyl carbon atom of pyruvate. (b) 5 mCi/mM. The specific activity is halved because the number of moles of product (pyruvate) is twice that of the labeled substrate (glucose). 3.

A product of a pathway serves as a competitive inhibitor of an early enzyme in the pathway. A molecule bound to an allosteric site affects the active site of several subunits. Several substrate molecules can be catalyzed by the same enzyme. A substrate binds to an active site and inhibits cooperation between enzymes in a pathway.

The reaction catalyzed by LDH is the reduction of pyruvate to lactate (leading to lactate accumulation) and the oxidation of NADH to NAD+: You will homogenize tissues and place the homogenate in a cuvette along with saturating concentrations of substrate (pyruvate and NADH).

Under aerobic conditions, pyruvate is converted to acetyl CoA and oxidation continues in the citric acid cycle. Under anaerobic conditions, pyruvate serves as an electron acceptor to recycle NAD+. The oldest bacterial fossils are more than 3.5 billion years old, appearing long before appreciable quantities of O2 accumulated in the atmosphere.

If O2 is present, the chemical energy stored in pyruvate and NADH can be extracted by pyruvate oxidation, the citric acid cycle, and oxidative phosphorylation. Concept 9.3 After pyruvate is oxidized, the citric acid cycle completes the energy-yielding oxidation of organic molecules

11. As a result of glycolysis, pyruvate oxidation and the citric acid cycle, only a small portion of the energy of glucose has been converted to ATP. At this point, the majority of the usable energy is contained in: Acetyl coenzyme A c. NADH and FADH2. Pyruvate d. Water
