Answer: Despite the availability of antibiotics that lyse E coli cells, the reason this is NOT recommended in course of treatment is because the antimicrobial agents may trigger the lytic cycle and result in increased toxin expression.
Explanation:
Shiga toxin (Stx) are toxins which are produced by shiga toxin-producing Escherichia coli ( STEC). The antimicrobial agents may also trigger the lytic cycle and result in increased toxin expression.
The steps involved in herpes simplex virus lytic cycle are: attachment on the epithelial cells. Penetration of the herpes virus inside the cell. Uncontrolled replication of the virus takes place. The virion gets assembled and finally released by bursting the cell.
Explanation:
The lytic infection of the virus results in breaking of bacterial or any cell after its replication.The lytic infection is phage infecting bacteria and getting replicated and bursts the cell of bacteria.
There are 5 stages in which lytic infection takes place in any virus like herpes simplex virus:
Attachment on bacterial cell wall:
penetration of virus
biosynthesis
maturation
release of virions
During the infection the HSV genes are expressed in the epithelial cells and get replicated resulting in sores and irritations as in genitals.
the cycle is generally 18- 20 hours long.
The first is (D), the second is also (D)
Substances that store chemical energy are primarily fuels such as coal, wood, natural gas, petroleum and propane, as well as foods, batteries and matches. Encyclopædia Britannica defines chemical energy as energy stored in the bonds of chemical compounds that can be released during a chemical reaction.
