Thus bcl-2 can protect cells from undergoing apoptosis even if the cells lack a functional respiratory chain.

It was not until 1925 when David Keilin discovered cytochromes that the respiratory chain was described.

This mitochondrial chromosome contains genes for redox proteins such as those of the respiratory chain.

Tissues from elderly patients show a decrease in enzymatic activity of the proteins of the respiratory chain.

Copper damages the respiratory chain in Escherichia coli cells.

As an immediate result the respiratory chain shuts down by inhibiting electron transfer.

His later research showed a relation between the respiratory chains in plants and animals.

In bacteria, this problem is solved by coupling oxidative folding to the respiratory chain.

These respiratory chains therefore have a modular design, with easily interchangeable sets of enzyme systems.

It is an inhibitor of cellular respiration by blocking the respiratory chain at complex II.
