The answer is <span>The release of secretin, which triggers the liver to release bile.
Secretin is the hormone released from the duodenum. It signals the secretion of bile in the liver. Bile helps digestion of lipids in the stomach.
Through the process of elimination:
- Pepsin is a hormone that breaks down proteins to the smaller peptides. So, pepsin does not breaks down lipids of high-fat meal.
- Gastrin is a hormone that triggers the gastric glands to secrete hydrochloric acid and pepsinogen, inactive form of pepsin.</span>
Answer:
Explanation:
A protease is an enzyme that catalyzes the hydrolysis of the peptide bonds that tie polypeptide chains together, releasing individual amino acid subunits. The L and D nomenclature for amino acids defines the structure of the glyceraldehyde isomer through which the amino acid can be produced.
SEE BELOW FOR THE APPROPRIATE STRUCTURES.
We need to figure out why swine proteases hydrolyze L-amino acids but not D-amino acids in any way. we know that enzymatic catalysts act as polypeptides if you can recall. They must retain a very precise three-dimensional structure for a catalytic activity to occur. Substrates that do not quite match the required configuration at the active site will not be reacted to — this is a "lock and key" style.
The present exercise may be explained by the fact that the configuration and structure of D-amino acids prevent them from binding properly to the active site of the protease enzyme. Perhaps they're pointed in the wrong direction, or perhaps there happens to be missing electrical interaction that's needed to keep the substrate in position.
Nonetheless, L-amino acids, on the other hand, seem to have the right configurational aspects in the active site and are hydrolyzed.
Answer: D. They must eat in order to gain nutrition
Explanation:
Am certain that the factor that prevents us from finding fossils from the Precambian era is that Most rocks from that era are deeply buried. The precambrian is the informal name for the large expanse of time preceding the current Phanerozoic Eon. It began with the Earh's Formation about 4.5 billion years ago and lasted until the advent of multicellular life about 542 million years ago.
Orbital period is the <span> time taken for a given object to make one complete </span>orbit around another object. Mercury orbits the Sun in 88 days. Therefore, Mercury's orbital period is calculated by (88/365.25) or .241 Earth years. Hope this answers the question.
