Answer:
True.
Explanation:
Rotenone is a broad spectrum pesticide and insecticide and is also considered as a non-selective piscicide.
The action mechanism of the rotenone has been described below -
It interferes with the electron transport chain which occurs in mitochondria of the cells. Here the transfer of electrons from complex I to the ubiquinone is inhibited by the rotenone. As a result, ATP formation with the help of NADH is also inhibited. When electron transport fails, oxygen in the cell is reduced to oxygen radical which further damages DNA and other components present in the mitochondria.
Well collagen is a globular protein with a tertiary structure. when you heat it up the energy will break the bonds that form between the chains of amino acids such as hydrogen and ionic bonds which will cause the shape of the collagen molecule to change and become less ridged and stable and more fluid.
