Name two different cellular functions that require energy that parallel human energy-requiring functions.

DNA/RNA synthesis and transport across the membrane.

Explanation:

The DNA and RNA synthesis is energy requiring process. The ATP is broken down and two phosphates from it are used for incorporation to nucleic acid.

The ATP is also required to transport vesicles across the membrane. Thus the two process that require energy are DNA / RNA synthesis and vesicle transport.  

answer: the correct option is d. enzyme

lactase and carbonic anhydrase are the examples of enzymes.

lactase is an enzyme, which is present in the small intestine of mammals. it in the digestion of the disaccharide, lactose ( milk sugar) by converting it into two monosachharide, which are glucose and galactose.

carbonic anhydrase is present in the red blood cells. this enzyme plays significant role in the transport of co₂. it in the conversion of co₂ and h₂o into carbonic acid, which is then dissociated into bicarbonate ions and hydrogen ions.
