Me Durning Finals.

I have decided to share how I revise for math since math has always been one of my best subjects.

Do homework. This may not seem crucial but it is important as homework helps you to revise what you have learnt in class.

Ask when you are in doubt. This is pretty self explanatory but math is essentially a subject which builds on what you have learnt in the past. Thus, your foundation for math must be strong. Ask your teacher asap when you don’t understand the concept.

Do assessment books. Books like the ten year series is important to give you a feel of what o-level math examinations questions are like. Basically, just do assessment books to prepare for whatever major examinations you are attending for.

Revise all of your worksheets, textbook and notes. Improving math, be better at solving equations, etc is all about practicing. You can try redoing all the questions in your textbook, notes and worksheets.

Alternatively, you can also come up with your own questions simply by changing the values in a sample question.

There are also lots of resources out there such as Photomath and Khan Academy (these are the ones I personally use) which helps you to better grasp the mathematical concept.

It is the most important to remember the formulas. I usually write down all the formulas I need to remember on the formulas printable designed by @emmastudies

Math problems are pretty standard so you can try to familiarise the method used to solve certain hard problemsums.

Lastly, definitely do not try to cram math. Math has a lot of topics so it is not a good idea to study the day before.

Antimicrobial Agents  - Cell wall inhibitors

Based on mode of action • divided into families based on chemical structure

 Modes of action Interference with: 

cell wall synthesis 

protein synthesis 

nucleic acid synthesis 

plasma membrane integrity 

metabolic pathway 

Inhibitors of Bacterial Cell Wall (peptidoglycan) Synthesis 

The Beta-lactam Family 

The Glycopeptides 

Peptidoglycan is composed of N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM) repeat units, and amino acids.  Each NAM is linked to peptide chain and the peptide chains are cross-linked.

β-lactams 

Includes penicillin derivatives (penams), cephalosporins (cephems), monobactams, and carbapenems.

class of broad-spectrum antibiotics containing a β-lactam ring

Bacterial transpeptidase enzymes are responsible for catalysing cross-linking of the peptide chains

β-lactam ring bind to these transpeptidases – this inhibits cross-linking between peptide chains and prevents synthesis of stable PG

Cell wall synthesis ceases and the bacterial cells eventually die due to osmotic instability or autolysis. 

Glycopeptides 

Polypeptide agents - basic structural elements amino acids 

Vancomycin: 

complexes with peptide portion of peptidoglycan’s precursor units 

vancomycin is a large hydrophilic molecule able to form hydrogen bonds with the terminal D-alanyl-D-alanine moieties of the NAM/NAG-peptides

preventing PG transglycosylation reaction – PG precursor subunits (NAG-NAM+peptide) cannot be inserted into peptidoglycan matrix;

Vancomycin also alters bacterial-cell-membrane permeability and RNA synthesis

Uses:  serious Gram positive infections e.g. MRSA wound infection

Adverse effects:

damage to auditory nerve 

hearing loss (ototoxicity) 

“Red man/neck” syndrome - rash on face, neck, upper torso 

Horizontal gene transfer

Archaea

Archaeans are single-celled and join bacteria to make up the Prokaryotes.  The Archaea classification is a very recent discovery, due to the similarities in appearance and behaviour to bacteria they weren’t separated until the late 1970′s. They mostly live in extreme environments and can be sub grouped: 

Methanogens - produce methane gas as a waste product of their “digestion,” or process of making energy.

Halophiles - live in salty environments.

Thermophiles - live at extremely hot temperatures.

Psychrophiles — those that live at unusually cold temperatures.

Like bacteria, archaea lack a true nucleus. Both bacteria and archaea usually have one DNA molecule suspended in the cell’s cytoplasm contained within a cell membrane. Most, but not all, have a tough, rigid outer cell wall.

use a variety of substances for energy, including hydrogen gas, carbon dioxide and sulfur. 

many archaea thrive in conditions mimicking those found more than 3.5 billion years ago. [eg oceans that regularly reached boiling point — an extreme condition not unlike the hydrothermal vents and sulfuric waters where archaea are found today]
