Inessa05 [86]

The correct answer is antigens and epitope.
An antigen is a substance which triggers an immune response in an organism. This can be either a foreign substance, such as a pathogen, or a specific part of the host organism (in this case this is an autoimmune response). The presence of an antigen activates a specific part of the immune system, called antibody. Each antigen has a specific antibody, which is tailored by the immune system accordingly. More specifically, the antibody has a specific structure, called paratope, which is complementary and binds like a key to a specific structure of the antigen, called epitope.

Answer:

Intracellular receptors are located within a cell and bind to molecules that cross directly through the membrane. Membrane receptors are located in the membrane, bind to molecules that cannot cross it, and transmit the signal to the cell interior by changing shape.

Explanation:

Amylase is a digestive enzyme secreted and is responsible for breaking down <u>starch.</u>

Digestion describes the intake, chemical and physical breakdown, absorption of nutrients and excretion of food. Alpha amylase, an enzyme produced in the pancreas, is found in human saliva; it catalyzes the breakdown of starch into glucose

Further Explanation:

Food is chemically and mechanically broken down into into smaller particles. This begins in the mouth, where food is mechanically crushed by the teeth, and mixed with saliva to allow water based enzymes like lingual lipase and amylase to work;- it's then transported to the stomach via the esophagus.

Alpha amylase, an enzyme produced in the pancreas, is also found in human saliva; it catalyzes the hydrolysis, or breakdown of starch into glucose in the stomach as gastric amylase. Amylase acts on polysaccharides bonds at random points along the chain by splitting the α 1-4 glycosidic bonds.
