खालील संप्रेकापैकी कोणते विसंगत आहे ? / Which of the following hormones is odd ?
Glucocorticoids, progesterone and testosterone are all steroid hormones, made from cholesterol by the adrenal cortex and the gonads. Insulin is a protein (peptide) hormone secreted by the beta cells of the pancreas, so it is the odd one out.
खालीलपैकी कशास एंजाइमस्चा को-फॅक्टर असे म्हणता येईल ? / Which of the following may be called as co - factor of an enzyme ?
Co-factors are non-protein chemical compounds or metallic ions that are bound to an enzyme and are required for the enzyme's biological activity.
नायट्रोजन स्थिरीकरण मध्ये मूलभूत गरजेचे घटक नमूद करा. The fundamental requirements for nitrogen fixation are :
(a)नायट्रोजनज / Nitrogenase
(b)फेराँडॉक्सीन / Ferredoxin
(c)एटीपी / ATP
(d)एरोबीक कंडीशन / Aerobic conditions
Biological nitrogen fixation fundamentally requires the enzyme nitrogenase, the electron donor ferredoxin, and ATP for energy. Aerobic conditions are generally unfavorable since nitrogenase is sensitive to oxygen.
