Pakistan MCQs

Water absorbs substantial heat with a small temperature rise.
This stabilizes cells, bodies and habitats.

Photoreceptors respond to electromagnetic radiation in the visible range.
They are found in the retina.

Beta oxidation breaks fatty acids into acetyl-CoA units.
Acetyl-CoA enters the Krebs cycle.

Freezing arranges water molecules in an open lattice.
The resulting solid is less dense than liquid water.

Photoreceptors respond to electromagnetic radiation in the visible range.
They are found in the retina.

Deamination removes nitrogen from amino acids.
The remaining carbon skeleton can enter glycolysis or the Krebs cycle.
