Concept explainers
Interpretation:
The similarity of the evolutionary implications in the structure and function of ATP synthase in chloroplast and mitochondria is to be explained.
Concept Introduction:
The energy of the
An electron transport chain is the series of electron transfers from an electron donor to an electron acceptor. It is referred to as a
It is the last component of aerobic respiration and is the only reaction that utilizes atmospheric oxygen. It takes place in the inner mitochondrial space.
