It is (D) Carbon dioxide.
in lactic acid=C6H12O6 to produce 2C3H6O3+Energy.
in alcoholic fermentation=C6H12O6 to produce 2C2H5OH+2CO2.
therefore all of them produce (D) Carbon dioxide.
By manipulating the substrates of the reaction, the enzyme can lower the necessary energy needed to make the reaction occur.
<span>Villi increases surface area for absorption as it contains lacteal which absorbs glycogen and fatty acids. blood capillaries in villi absorbs amino acids and glucose and then send them in the liver</span>
