The anaplerotic function may be carried out by either of two enzymes that catalyze the fixation of carbon dioxide onto a three-carbon compound, either pyruvate (reaction [50]) or phosphoenolpyruvate (PEP; [50a]) to form oxaloacetate, which has four carbon atoms. Both reactions require energy....
An exergonic reaction a. requires more energy than it releases b. creates an explosion c. does not require energy to start d. releases more energy than it requires e. absorbs heat from the environment. All of the chemical reactions that occur in a cell are called a. homeostasis. b. meta...
All materials require the presence of oxygen for burning to take place. Any substance burning in air will combine with oxygen. This process is called combustion, and is an example of a chemical reaction between the burning substance and the oxygen in the air, the reaction producing heat. The...
if you see oxygen is a reactant along with a hydrocarbon, and water and carbon dioxide are two products of a reaction, then it is probably a combustion reaction. Double-displacement reactions tend to involve ionic solutions that produce ionic compounds, one of which forms a precipitate;...
Glycolysis is an anaerobic reaction; that is, it can occur even in the absence of oxygen. The tricarboxylic acid cycle and oxidative phosphorylation, on the other hand, require oxygen. Glycolysis forms the basis of anaerobic fermentation, and it presumably was a major source of ATP for early ...

Some reactions require the input of energy to form new chemical bonds, this creating more complex molecules from simpler ones and storing free energy in those new chemical bonds. Those reactions are called ___. If electricity flows toward the negative...

Introduction: There are five types of chemical reactions that can occur; synthesis (A+B=C), decomposition(C=A+B), single replacement (A+BC=B+AC), double replacement (AB+CD=AD+CB) , and combustion. A combustion reaction consists of a hydrocarbon plus oxygen gas which yields carbon dioxide...
