Answer
Better lactam antibiotics are antibiotics used in treatment of of severe infection caused by Bacteria.
Beta lactam antibiotics contain beta lactam ring in their molecular structure.
The major subtypes of Beta lactam antibiotics include : Penicillin, cephalosporins, monobactams and carbapenems.
Explanation:
Penicillin : 1) Bind to Penicillin binding sites (PBS)
2) they are vulnerable to The enzyme penicillinase and other b-lactamase
3 ) Penicillin occurs naturally and can also be synthesized
Cephalosporins : 1) they also bind to Penicillin binding sites too
2) just like penicillin, they are vulnerable to B-LACTAMASE, unlike penicillin, they are not vulnerable to penicillinase
Monobactams:
1) binds only to PBP3 but binds weakly to other BPPs
2) is resistant to B-LACTAMASE but is inactivated by ESBLs (Extended spectrum Beta lactamASE ).
Carbapenems :
1) They bind PBPs of most bacteria
2) they are resistant to most B- Lactamase
Answer:
to put it simply, no. no they cannot.
Explanation:
the reason being pollution means the result of pollutants in the environments, and pollutants are known as the CAUSE of pollution. 2 very different terms.
Fungi are either saprophytes or parasites
Answer - The polarity of the water molecule helps it to cohere to nearby water molecule. Forming a skin over.
Reasoning - Since the polarity is all close and wanting to bond they have a surface tension which come together to making a skin like over.
The process where 1 parent cell results in 2 daughter cells is Mitosis
