Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which passes high energy electrons into the electron transport chain
A
NADH & FADH2
B
ATP & ADP
C
citric acid
D
acetyl CoA
Explanation: 

Detailed explanation-1: -NADPH carries high-energy electrons to the electron transport chain in photosynthesis.

Detailed explanation-2: -NADH and FADH2 carry high-energy electrons to the electron transport chain in cellular respiration. NADPH carries high-energy electrons to the electron transport chain in photosynthesis.

Detailed explanation-3: -Electrons from NADH enter the electron transport chain in complex I, which consists of nearly 40 polypeptide chains (Figure 10.8). These electrons are initially transferred from NADH to flavin mononucleotide and then, through an iron-sulfur carrier, to coenzyme Q-an energy-yielding process with
