Answer:
Pepsin is the gastric enzyme that initiates protein digestion.
The pepsinogen is first produced by the stomach lining. This is the inactive form. It reacts with is the stomach acid ( dil Hcl) to form pepsin(active form).
The ducts in the pathway by which pancreatic juice flows from the pancreas to the duodenum is the pancreatic duct
The Amino acids formed from the breakdown of Protein helps in the synthesis of enzymes, hormones and other biological cell components.
Amino helps in the replacement of worn out tissues.
It also helps in mental development and reduction of fatigue.
Answer:
The comparison of proteins and polysaccharides establishes that they have similarity in both consist of linked monomers via the process dehydration reactions.
Explanation:
Both proteins and polysaccharides are polymers whose structure consists of the union of monomers. In the case of proteins the monomer is the amino acid, while in the polysaccharides can be glucose molecules.
The process of polymer formation is called polymerization, and one of the reactions that this process allows is <u>polycondensation</u>, where a water molecule is lost in the union of monomers.
The loss of water in a chemical reaction involves dehydration, a characteristic shared by the processes of adding monomers to proteins and polysaccharides.
The other options are not correct, because
- <em>Hydrolysis produces the rupture of molecules, with the intervention of water.</em>
- <em>Only polysaccharides are sugars bound by the dehydration synthesis process.</em>
- <em>Only proteins consist of amino acids linked through the process of hydrolysis.</em>
Answer:
In a redox reaction, a reducing agent will donate electrons to another chemical species and then it becomes oxidized.
Explanation:
A redox or oxidation-reduction reaction is a chemical reaction where exchange of electron(s) happen between two chemical species (molecule, atom or ion). In this reaction, one chemical species act as an oxidizing agent while another will be a reducing agent.
An example of redox reaction is given in the attachment.
In a redox reaction, the oxidation number of a reducing agent will be increased, whereas oxidizing agent will be reduced.
Answer: The lungs are well supplied with blood due to lots of capillaries covering the alveoli, constantly maintaining a large diffusion gradient, air is able to pass easily down this gradient due to the alveoli having very thin walls (one cell thick).
or
The alveoli are adapted to make gas exchange in lungs happen easily and efficiently. Here are some features of the alveoli that allow this: they give the lungs a really big surface area. they have moist, thin walls (just one cell thick)
Hope this helps......... Stay safe and have a Merry Christmas!!!!!!!!!!! :D
