Is energy released or not released during the reduction of N

... energy is not released during the reduction of NAD, but it does not make sense to me because I am of strong belief that all redox reactions are exergonic. For example the reduction of oxygen molecules following the oxidation of glucose releases a lot of energy. is the reduction of NAD a special ...

Gluconeogenesis

... and, to a lesser extent, in the cortex of kidneys. The process is highly endergonic until ATP or GTP are utilized, effectively making the process exergonic. For example, the pathway leading from pyruvate to glucose-6-phosphate requires 4 molecules of ATP and 2 molecules of GTP. Gluconeogenesis ...

Cellular Respiration

... isnt my strongest point could someone lend some advice on the chemical equation for the breakdown of ATP. Does the reaction release energy (exergonic/exothermic) or absorb energy (endergonic/endothermic)? Much Appreciated

Cellular Energy Questions

2. The oxidation of wood (fire) and the oxidation of glucose (respiration) are basically the same exergonic reaction. However the amount of heat released by fire would destroy a cell. Explain how a cell manages to harvest the energy stored in glucose and still maintain internal ...
