In the citric acid cycle (Krebs cycle), how many of each energy-rich molecule is produced? 1) When 13 molecules of pyruvic acid are broken down completely to CO2 and H2O in the presence of oxygen, how many molecules of ATP will be produced? 2) When 16 acetyl Co...
A glucose molecule is completely broken down to carbon dioxide and water in glycolysis and the citric acid (Krebs) cycle, but together these two processes yield only a few molecules of ATP. During the Krebs cycle: a. NADH is oxidized. b. ATP is produced. c. py...
The PCR cycle can be divided into three main aspects鈥攃arboxylation, reduction, and regeneration. The carboxylase also functions as an oxygenase; however, in high CO2, it catalyzes the addition of one molecule of CO2 to one molecule of ribulose-l,5-P2 with the formation of two molecules ...
The role of vitamin B12, as coenzyme of the methylmalonyl-CoA mutase in the entry of propionate into the Krebs cycle, which increases energy supply, also cannot be ruled out. Moreover, an adequate folate supply is critical for coordination of the distribution of vitamin B12 between cytosol (...
PCAs into biorenewable molecules has been explored, by restoring the carbon-hydrogen (C-H) bonds that were lost in their creation. This would need these biomolecules to undergo reactions called “dehydration” and “reduction,” that is, the reversal of the Krebs cycle — a complicated proce...
Iron (II), in the presence of other simple organic compounds, is able to convert, under a mild hydrothermal environment, pyruvate and glyoxylate into 9 of the 11 intermediates of the Krebs cycle [18]. In another work, the Krebs cycle was run non-enzymatically with the help of FeS and ...
Recent advances in organometallic chemistry and catalysis provide effective means for the chemical transformation of CO2 and its incorporation into synthetic organic molecules under mild conditions. Such a use of carbon dioxide as a renewable one-carbon (C1) building block in organic synthesis could ...
In total, two molecules of acetyl-CoA and one molecule of oxaloacetate are transformed to succinyl-CoA and malate. The emergence of both pathways in haloarchaea is probably a result of lateral gene transfer from bacteria. Haloarchaea using the glyoxylate cycle presumably acquired its key enzymes ...
To solve the question regarding the role of respiration in the production of carbon skeletons used for biosynthesis, we can follow these steps:1. Understanding Respiration: - Respiration is a metabolic process that converts
Explain the concept of the reverse Krebs cycle and forward Krebs cycle. Discuss the cyclic nature of the reaction in the Krebs cycle and the production of ATP molecules. What are the end-products of the Krebs cycle? What are the steps of the Krebs cycle?
