Considering the pentose phosphate pathway and the sulfate reduction pathway in bacteria;

What are these types of reactions called in biology? Bio degradation reactions or bio transformation reactions or something else? I wish to know whether there is a generalized names for these types of pathways.

    $\begingroup$ They usually have specific names - your example is the pentose-phosphate way (or pathway). $\endgroup$ – Chris May 27 '15 at 12:19
  • $\begingroup$ is there no generalized names for such pathways? $\endgroup$ – girl101 May 27 '15 at 12:24

    $\begingroup$ If you want it short: Pathway. Otherwise you could think about metabolic pathways or the specific names. $\endgroup$ – Chris May 27 '15 at 12:26
  • $\begingroup$ so these types of chained reaction like pathways have no special names... $\endgroup$ – girl101 May 27 '15 at 12:27
  • $\begingroup$ The special names of these chained reaction like pathways is metabolic pathways. This is it. For the first time in science, something actually has an intuitive name. $\endgroup$ – Remi.b May 27 '15 at 14:34

Short answer
Assuming you wish to have a common name for both of these (widely differing!) pathways I basically agree with @Chris, and I would go for general terminology, namely metabolic pathways.

The pentose-phosphate pathway is neither anabolic nor catabolic so those terms won't do. The pentose-phosphate pathway is, however, closely linked to general metabolism to supply the body with C5 sugars. So metabolic pathway sounds right to me.

The other pathway is a sulfate reduction pathway, which is an anaerobic respiration pathway that uses sulfate as the terminal electron acceptor instead of oxygen. It is an entirely different pathway. However, it too is neither catabolic or anabolic, but still closely linked to metabolism. Hence, metabolic pathway is applicable here too.
