Of the following given choices;

A) After binding to a protein molecule, the trypsin molecule is destroyed and must be replaced.

B) The combined trypsin and protein molecule is utilized for energy to power cellular functions.

C) After binding to the protein molecule, trypsin is converted to a lipid and used for energy storage.

D) The trypsin molecule is not chemically altered by the reaction with protein and may be used again.

The answer is; D.

Trypsin is not degraded in the process of breaking down a protein molecule hence continues to break down other proteins. The proteins bind to the active site of the enzyme and the peptide bond is hydrolyzed. The hydrolyzed protein then releases from the active site.

If a small amount of trypsin is left in a big jar of proteins, over time, the whole proteins will have been hydrolyzed because the enzyme is not degraded in a hydrolysis reaction.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.

Hunting in the darksome fish rely on senses beyond sight. in the darkness of the marianas trench, a fish called the rattail has an extremely sensitive sense of smell. the fish uses scent, rather than sight, to steer toward food. once it's near food, the rattail uses a special organ on the bottom of its chin to guide itself by feel.marine snowone staple of the deep sea diet is "marine snow," flakes of organic, edible substances that sink down from the upper ocean. animals at the ocean's bottom find sustenance in everything from the bodies of dead creatures to fecal matter. marine snow is diverse enough to support numerous species. for instance, several species of snails and worms feed exclusively on deceased whales.microorganismsthe deep sea is an intricate ecosystem, and even the ocean floor itself plays a part. hydrothermal vents are cracks in the sea floor where erupting magma mixes with ocean water to produce plumes of hot, sulfur-rich chemicals. some microbes can use these chemicals for energy, sustaining their existence and that of the animals who depend on their roles in the deep sea food chain.
