Why is salivary amylase active for only an hour or so, whereas lingual lipase isn't active until reaching the stomach

Biology
1 answer:
leva [86]1 year ago
3 0

Salivary amylase will be active for only an hour or so because the optimum pH for activity of amylase is about 6.7–7.0 which is available in the mouth but the pH of the stomach is acidic around 1-2 due to which the amylase enzyme becomes inactive in short-time.

The lingual lipase enzyme is present in the saliva but isn't active until reaching the stomach because this enzyme is acid stable and works efficiently in the stomach, not in the mouth.

Amylase enzyme is secreted in the mouth and is responsible for the breakdown of starch in food into sugars and it starts acting as soon as we put food in the mouth whereas Lingual lipase enzyme is secreted along with saliva but it is not active in the mouth rather its activity starts in the stomach which is responsible for the degradation of triacylglycerol molecules.

What are the genotypes of the parents? I'm guessing it's Yy and yy, but I'm not exactly sure.​
svet-max [94.6K]

Well since the capital letter is dominate and always takes power and the lower case letter is recessive doesn't take power. It would be 50%.

The answer would be Yy and yy :D

Can someone explain the process of RNA editing?
Talja [164]
The process of RNA editing is the alteration of the sequence of nucleotides in the RNA after it has been transcribed from DNA, but before it is translated into a protein. RNA editing occurs by two distinct mechanisms:<em><u /><u>Substitution</u> <u>editing </u></em>and <u><em>Insertion/</em></u><em></em><u><em>deletion</em></u><em> <u>editing</u></em>.

<u><em>Substitution editing</em></u> is the chemical alteration of individual nucleotides. These alterations are catalyzed by enzymes that recognize a specific target sequence of nucleotides:

*Cytidine Deaminases that convert a C in the RNA to uracil.

*<em />adenosine deaminases that convert an A to inosine,which the ribosome translates as a G.<span>Thus a CAG codon</span><span> (for Gln) can be converted to a CGG codon (for Arg).

<em><u>*Insertion/deletion editing</u></em><em><u /></em><u /> is the insertion or deletion of nucleotides in an RNA.

These alterations are mediated by guide RNA molecules that base-pair as best they can with the RNA to be edited and serve as a template for the addition( or removal) in the target.</span>
