Why are digestive enzymes in cell enclosed in a membrane-bound organelle

Biology
1 answer:
vodomira [7]3 years ago
5 0
The digestive enzymes can only recognize the structure of the substrate but can not recognize whether it is inside cell or from outside. So if there is no membrane, the enzyme will digest the structure of its own.

When the nurse researcher conducts an electronic literature search, the search yields more than 7000 citations for the topic. th
Sauron [17]
The correct answer is "the keywords were not sufficiently narrowed".
In this example, the literature research yielded a great and unmanageable number of citations. It is practically impossible to read all these citations and most probably some of these citations are not relevant to what the nurse researcher is looking for. Therefore, this literature research needs to be conducted again, by narrowing down the focus using more precise terms.

Why do researchers use rRNA in investigations of relationships between taxa that diverged hundreds of millions of years ago? See
cupoosta [38]

Answer:

DNA coding for rRNA changes relatively slowly

Explanation:

The ribosomal ribonuclei acid( rRNA ) is used for Ribosome synthesis. Ribosomes is the organelle for  translation of encoded amino acids in protein  synthesis in  the cells. The gene that codes for rRNA is called rDNA.Thus must of the functionalities of rDNA are encoded rRNA. Therefore researchers use rRNA for comparison investigations  because;

<u>1.The coding region on the rDNA is highly conserved, with low rate of polymorphism, thus rDNA for rRNA  transcriptions pathways is relatively slow compare to the one of  high rate of  polymorphism.</u>

<u />

2. Consequently the conserved region( well preserved amino acid sequence) of the rDNA encoded in rRNA, with  low polymorphism, and therefore  slow transcription pathways  enabled the use of rRNA for investigations of relationship between taxa. Since  rRNA is present across all organisms,prokaryotes and eukaryotes  the highly conserved coded region of low mutation and therefore slow changes, enable accurate comparison.
