In enzymology, a fumarate reductase (NADH) (EC 1.3.1.6) is an enzyme that catalyzes the chemical reaction succinate + NAD + ⇌ {\displaystyle \rightleftharpoons } fumarate + NADH + H + Thus, the two substrates of this enzyme are succinate and NAD + , whereas its three products are fumarate , NADH , and H + .
The effects of the NAD + /NADH ratio are complex, controlling the activity of several key enzymes, including glyceraldehyde 3-phosphate dehydrogenase and pyruvate dehydrogenase. In healthy mammalian tissues, estimates of the ratio of free NAD + to NADH in the cytoplasm typically lie around 700:1; the ratio is thus favorable for oxidative reactions.
Thus, the two substrates of this enzyme are L-glutamate and NAD +, whereas its 4 products are L-glutamine, 2-oxoglutarate, NADH, and H +. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH 2 group of donors with NAD + or NADP + as acceptor. This enzyme participates in glutamate metabolism and nitrogen ...
The 3 substrates of this enzyme are NADH, H +, and monodehydroascorbate, whereas its two products are NAD + and ascorbate. This enzyme belongs to the family of oxidoreductases, specifically those acting on NADH or NADPH, with a quinone or similar compound as an acceptor. The systematic name of this enzyme class is NADH: monodehydroascorbate ...
Out of the cytoplasm it goes into the Krebs cycle with the acetyl CoA. It then mixes with CO 2 and makes 2 ATP, NADH, and FADH. From there the NADH and FADH go into the NADH reductase, which produces the enzyme. The NADH pulls the enzyme's electrons to send through the electron transport chain. The electron transport chain pulls H + ions ...
In enzymology, a hydroxylamine reductase (NADH) (EC 1.7.1.10) is an enzyme that catalyzes the chemical reaction.. NH 3 + NAD + + H 2 O hydroxylamine + NADH + H +. The 3 substrates of this enzyme are NH 3, NAD +, and H 2 O, whereas its 3 products are hydroxylamine, NADH, and H +.
1/2 O 2 + NADH + H + → H 2 O + NAD + The potential difference between these two redox pairs is 1.14 volt, which is equivalent to -52 kcal/mol or -2600 kJ per 6 mol of O 2. When one NADH is oxidized through the electron transfer chain, three ATPs are produced, which is equivalent to 7.3 kcal/mol x 3 = 21.9 kcal/mol.
