Question

Choose the correct answers from the alternatives given :
The primary energy carrier between the Krebs cycle and the electron transport system is

• A. NADH
• B. ADP
• C. FADH ${}_2$
• D. CO${}_2$

Answer 1

The correct option is A NADH

Krebs cycle is followed by an electron transport system which occurs in the mitochondria, these are the steps of aerobic respiration that are linked together by an energy carrier. 3 NADH is produced in one turn of the Krebs cycle which further carried to the inner mitochondrial membrane to conduct an electron transport system . NADH is the first complex of the electron transport system.

So, the correct option is ' NADH'.
