Exo- definition, a combining form meaning “outside,” “outer,” “external,” used in the formation of compound words: exocentric. The endo -enzymes produce polymeric and/or oligomeric compounds (depending on the DP of the substrate and cleavage point), which may be further hydrolyzed to smaller compounds. endo-Enzymes randomly cleave the glucosidic linkages of the polysaccharide, whereas exo-enzymes act from the nonreducing and, in some cases, from the reducing end of the substrate. Give contextual explanation and translation from your sites ! Here "longest" and "shortest" refer to the number of atoms that comprise the bridge. ○   Wildcard, crossword Contact Us So, finally, $$\Delta H=Q$$ So, for a process carried out at constant pressure, if the heat added to the system is positive (endothermic), $\Delta H$ is positive and if the heat added to the system is negative (exothermic, heat removed from system), $\Delta H$ is negative.
