The three minor source of high energy ATP are oxidative phosphorylation,glycolysis and TCA.

d) Phosphagen act as storage forms of high energy phosphate ,as creatine phosphate and glucose-1-phosphate .

hydrolytic splitting of PPi , catalyzed by inorganic pyrophosphatase

ATP can also be hydrolyzed directly to AMP, with the release of PPi

AMP able to act as a metabolic (allosteric) signal to increase the rate of catabolic reactions

Glucose to glucose 6 phosphate reaction is endergonic reaction

Some problems related to energy:.

Energy may be transferred into another form of energy, or
may be transformed from one part of the system to another.

ΔG may be larger or smaller than ΔG0 depending on the concentrations of the various reactants

The terms exergonic and endergonic, rather than the normal chemical terms “
exothermic” and “endothermic,” are used to indicate that a process is
accompanied by gain or loss, respectively

crossroads is/are:

One possible mechanism of coupling could be envisaged if a common
obligatory intermediate (I) took part in both reactions, that is,

All values taken from Jencks (1976), except that for PPi which is from....

There are ............. high energy P-bonds in an AMP molucle is

when available energe reserve are depleted causes

About the ΔG, which of the following statements is FALSE?

Excess storge of surplus energe not causes

Reactions that release free energy and increase entropy are called ……………… reactions.
