Card 1एंजाइमों की मूल बातें

एंजाइम क्या हैं?

Answer

एंजाइम जैव-उत्प्रेरक होते हैं जो in vivo और in vitro दोनों में जैवरासायनिक अभिक्रियाओं को उत्प्रेरित करते हैं। वे स्वयं बदले बिना अभिक्रिया की दर बहुत बढ़ा देते हैं।

Card 2Enzyme basics

What are enzymes?

Answer

Enzymes are biocatalysts that catalyse biochemical reactions both in vivo and in vitro. They increase the rate of reaction greatly without being changed themselves.

Card 3Enzyme basics

Are all enzymes proteins?

Answer

All enzymes are proteins except a small group of catalytic RNA molecules called ribozymes. Ribozymes are the exception to the general rule.

Card 4एंजाइमों की मूल बातें

क्या सभी एंजाइम प्रोटीन होते हैं?

Answer

सभी एंजाइम प्रोटीन होते हैं, सिवाय catalytic RNA अणुओं के एक छोटे समूह के जिन्हें ribozymes कहा जाता है। Ribozymes सामान्य नियम का अपवाद हैं।

Card 5एंजाइम सहकारक

कोफ़ैक्टर क्या है?

Answer

कोफ़ैक्टर एक गैर-प्रोटीन घटक है जिसकी कुछ एंजाइमों को उत्प्रेरकीय सक्रियता के लिए आवश्यकता होती है। यह एक कार्बनिक coenzyme या Fe2+, Zn2+, या Mg2+ जैसा धातु आयन हो सकता है।

Card 6Enzyme cofactors

What is a cofactor?

Answer

A cofactor is a non-protein component needed by some enzymes for catalytic activity. It may be an organic coenzyme or a metal ion such as Fe2+, Zn2+, or Mg2+.

Card 7Enzyme cofactors

What is a holoenzyme?

Answer

A holoenzyme is an enzyme plus its cofactor. It is the complete active form of the enzyme.

Card 8एंजाइम सहकारक

होलोएंजाइम क्या है?

Answer

होलोएंजाइम एंजाइम और उसका cofactor मिलकर बनते हैं। यह एंजाइम का पूर्ण सक्रिय रूप है।
