Tsarin Halittar Jiki: Ginawa da Ajiyar Makamashi
Tsarin hana samar da makamashi (anabolism) tsari ne na rayuwa wanda aka mayar da hankali kan gina ƙwayoyin halitta masu rikitarwa daga waɗanda suka fi sauƙi. Wannan galibi ya ƙunshi amfani da makamashi, yawanci a cikin nau'in ATP (adenosine triphosphate), don samar da sabbin haɗin sinadarai. Tsarin hana samar da makamashi yana da alhakin girma da kula da ƙwayoyin halitta da kyallen takarda, da kuma adana makamashi a cikin nau'in manyan ƙwayoyin halitta kamar glycogen da mai.
Misalan Tsarin Anabolic
1. Haɗakar Sunadaran: Amino acid, waɗanda su ne tubalan gina sunadaran, ana haɗa su ta hanyar haɗin peptide don samar da sunadaran da ke aiki a matsayin enzymes, hormones, da kuma sassan tsarin ƙwayoyin halitta.
2. Haɗakar Lipid: Ana haɗa kitse mai da glycerol don samar da triglycerides, waɗanda ake adana su a matsayin taska mai kuzari a cikin kyallen adipose.

Anabolism wani muhimmin tsari ne wanda ke ba da damar girma ta jiki, gyara nama, da adana kuzari. Ba tare da hanyoyin anabolic ba, jiki ba zai iya gyara nama da ya lalace ba, daidaita shi da motsa jiki, ko adana kuzari don amfani lokacin da ake buƙata.
Katabolism: Rushewa da Sakin Makamashi
Catabolism akasin anabolism ne.
