$II$. The Calvin pathway occurs in the chloroplast of bundle sheath cells of $C_4$ plants.
$III$. Yeast poison themselves when the concentration of alcohol reaches $7\%$.
$IV$. Oxygen is a final hydrogen acceptor during aerobic respiration.

Assertion $:-$ There is not a complete one-to-one overlap between the absorption spectrum of chlorophyll $a$ and the action spectrum of photosynthesis.
