[TOPIC 5] Introduction To Microbial Metabolism

Assalamualaikum w.b.t. 

Hi~ 

Since we already know about the formation and structures of amino acids and proteins. The current topic will now discuss on the functions and metabolism of the proteins. 

When I hear or come across the word 'protein', the first thing that comes to mind is 'enzyme'. He he. How about you? 

This topic firstly exposed us on metabolism such as what's the meaning, and the process involved; which is anabolism and catabolism. 

It's important to know what those two words mean. And also identify which process release energy and absorb energy. 

Next, the types of enzymes were also included in the topic. There are six of them. I have already 'met' these six types of enzyme before during our last semester which is included in Biomolecules subject. 

Other than the types of enzymes, the other important thing to know is the properties of enzyme.

This is really important, right! 

Some of the properties of the enzyme are enzymes are specific, can be inhibited by certain conditions and not used up in a chemical reaction. (Make sure you know the other functions too, I only include some of it~). 

In addition to that, it is weird if the mechanism of enzyme is not included, right? So, of course it is crucial to know that too~ 

There are two mechanisms though, the lock and key method and the induced fit method. 

I found a cute and an interesting picture of the lock and key method! So that people can memorise it easier and more fun, in some sort, because it's related to our daily life; the key. Hehe. 

If there is a method on how to make the enzyme works, there should be reasons or conditions on how to disable the enzyme functions, right? 

Yes! 

There are a few factors affecting enzyme's functions which is concentration of substrates enzymes, pH, temperatures and enzyme inhibitors. 

Make sure to know how each factor contribute to inhibit the enzyme's activity. 

Especially on the types of inhibitions. Each of the inhibition; competitive inhibition, non-competitive inhibition have their own mechanisms; where they will interact with the enzyme either at the active or the allosteric site and the effects on the products formation. 

That's all from me~
