Which of the following are best described as short chains of amino acids that are very stable and can have a variety of differen
t antimicrobial activities, such as forming pores in bacterial plasma membranes and inhibiting cell wall synthesis? A) siderophores
B) antimicrobial peptides
C) mannose-binding lectin
D) antiviral proteins
Which are known to be natural carbohydrate binding proteins and are highly specific to some sugar groups of other molecules.
Explanation:
Lectins are widely distributed in nature and are isolated from various microorganism. lectins binds to sugar molecules on the microbial surface as potent antimicrobial agents. The Mannose (carbohydrate) binding lectins have the ability to form pores in the bacterial cell membrane which causes changes in the permeability of cells and will interact with cell wall components.
Answer: Those which can adapt and withstand the high acidity levels of water.
The pond slowly becomes more acidic due to release of chemicals from a nearby factory. The chemicals released are acidic and toxic which will cause biomagnification in the pond water. Those organisms which can withstand the high acidic pH of water will survive. Others which can undergo adaptations can also survive.
