Given below are two statements: Statement (I): NADH ₂ ( NADH + H ^+ ) and FADH ₂ that are produced during glycolysis, connecting link reaction and Krebs cycle, are oxidised with the help of various electron carriers and enzymes. Statement (II): These carriers and enzymes are arranged in the cytoplasm in the form of various complexes as complex I, II, III, VI and V. In light of the above statements, choose the most ap
Options
- ABoth Statement (I) and Statement (II) are true.
- BBoth Statement (I) and Statement (II) are false.
- CStatement (I) is true but Statement (II) is false.
- DStatement (I) is false but Statement (II) is true.
Correct answer
C. Statement (I) is true but Statement (II) is false.
Step-by-step solution
Statement (I) is true because NADH + H ^+ and FADH ₂ produced during glycolysis, the link reaction, and the Krebs cycle are oxidised by the electron transport system (ETS) which consists of various electron carriers and enzymes. Statement (II) is false because the electron carriers and enzymes of the ETS are located in the inner mitochondrial membrane, not in the cytoplasm. Furthermore, they are arranged in the form of complexes I, II, III, IV, and V, not VI. Answer: Statement (I) is true but Statement (II) is fals
