is catecholamine increases both protein anabolism and protein catabolism

Answer 1

Catecholamines, such as adrenaline (epinephrine) and noradrenaline (norepinephrine), generally increase protein catabolism rather than protein anabolism.

Catecholamines are released during stress or exercise and have various effects on the body to prepare it for increased energy demands. One of these effects is to mobilize energy stores by promoting the breakdown of proteins and the release of amino acids into the bloodstream. The amino acids can then be used as an energy source or for gluconeogenesis (formation of glucose).

On the other hand, anabolism refers to the building and synthesis of proteins or other molecules in the body. Catecholamines are not typically associated with anabolic processes. Hormones like insulin and growth hormone play more prominent roles in protein synthesis and anabolism.

So, while catecholamines can increase protein breakdown and catabolism, they do not have a direct effect on protein anabolism.
