Amino Acid and Proteins ~

Assalamualaikum and Good morning Dr Wan.

Chapter 4 is conducted by Dr Amalia. She’s so cute! Hahahaha

So, the next chapter is on Amino Acids and Proteins.

Basically, we’ve learnt all of this in last semester in Biomolecules.

We’ve learnt about the basic structure of amino acid.

We also learnt that the classification of amino acid is based on the R-group

Amino acids make a peptide bond from N-terminus to C-terminus and become a protein.

In protein, there are primary structure, secondary structure, tertiary structure, and quaternary structure.

There two things that we are not learn yet in Biomolecules, that are loop and turn. 

Turns is shorter than loops means they only contain not less than 5 amino acids per turns. 

While loops is longer that is up to five amino acid that reverse a direction of a polypeptide chain.

At the end of the class, Dr Amalia gave us some quiz on the chapter that we’ve learnt that day.

I think, that’s all for this chapter, Thankyou! J

Till we meet again! XOXO

Intracellular Structures of Prokaryote

Assalamualaikum and Good morning Dr Wan.

The next chapter is Intracellular Structures of Prokaryotes.

In this chapter, we’re doing in group a presentation on topic that we chose.

We’ve learnt about the structure, chemistry and function of each of the structures internal to the cell wall of prokaryotes.

The intracellular structures include:

• Plasma membrane

·         Passive transport

ü  Simple diffusion

ü  Facilitated diffusion

ü  Osmosis

·         Active transport

ü  Active transtport

ü  Group translocation

• Cytoplasm

• Nuclear area

• Plasmid

• Ribosomes

• Inclusions   

        Granules

ü  Metachromatic granules

ü  Polysaccharide granules

ü  Sulfur granules

·         Vesicles

ü  Gas vacuole

ü  Carboxysome

ü  Magnetosome

ü Lipid deposits

• Endospores and the infectious disease caused by endospores 

Cell Wall and Membrane Structure of Prokaryote~

Assalamualaikum and Good morning Dr Wan.

Today I want to summarize the next chapter that is Cell Wall and Membrane Structure of Prokaryote.

 

This topic is quite simple. We just learn again what we’ve learnt in first semester and second semester.

We’ve learnt about the external structure to the cell wall and their function. The external structure include :

• Glycocalyx
• Flagella
• Axial filaments
• Fimbrae
• Pili

We also learn about the differences and similarities of cell wall for Gram-positive and Gram-negative bacteria

Comparison between the cell wall of Gram-positive and Gram-negative bacteria

I think that’s all roughly about this chapter. Thankyou

Till we meet again! XOXO

Introduction to Prokaryotes

Assalamualaikum and Good morning Dr Wan.

I hope you are good.

Today, I want to write about the first chapter of this semester course that is Physiology (BMY3103). The first chapter is Introduction to Prokaryote.

Prokaryotes have two domains that are Bacteria and Archaea.

Prokaryotes are the organisms that lack a nucleus or any other membrane bound organelles. Most of them are unicellular.

What I’ve learnt in this topic are :

                  Prokaryote diversity

·         Proteobacteria

·         Gram positive bacteria

·         Cyanobacteria

·         Spirochetes

·         Green sulfur bacteria and green non-sulfur bacteria

·         Archaea

Differences between Prokaryotes and Eukaryotes

Comparison between Bacteria and Archaea

     

                 The characteristics and function of cell  structure

·         Capsule

·         Cell wall

·         Cytoplasm

·         Plasma membrane

·         Pili

·         Flagella

·         Ribosomes

·         Plasmids

·         Nucleoid region

I think that’s all roughly about this chapter. Thankyou :) 

Till we meet again! XOXO
