THE MIGHTY MITOCHONDRIA!

The Mighty Mitochondria: Powerhouse of the Cell

Mighty Mitochondria

I produce ATP,
That stands for energy!
You couldn't move a muscle
If it wasn't for me.
To all other organelles,
You know I've got you beat.
I'm the strongest of the strong
I am without defeat.
So, you better watch out!
Here comes the powerhouse!

Though mitochondria may sound like a complicated over-your-head scientific terminology that leaves you scratching your head as you attempt to pronounce it properly...it's really not as difficult as it seems!

What is it?

The mitochondria is the organelle
(within both plant and animal cells) that transforms the food you eat or energy absorbed into ATP (energy). For plants, this process is called photosynthesis (through sunlight), and for animals, it is called cellular respiration.

Some cells require more energy than others, so they contain more mitochondria. For example, brain cells need lots of energy in order to communicate with each other and with other parts of the body. It's the same for muscle cells, as they  need extra energy to help you maintain posture and

contract muscles! 

Composition of the Mitochondria

The mitochondria are round and tube-like in shape. They are surrounded by an outer membrane, followed by an inner membrane which has many folds. Within, there are cristae and the mitochondrial matrix. The matrix holds ATP synthase particles, ribosomes, granules, and DNA.


Now, isn't that just amazing? How can something so small hold so much? Mitochondria are the reason you can breathe, move and even think. You wouldn't be able to survive without these little things!

This video illustrates the importance and utter magnificence of mitochondria within the cell.

Join mitochondria lovers all around the world!

Don't you forget it!

MITOCHONDRIA IS THE POWERHOUSE OF THE CELL!

VOTE RIBOSOME!!!!!!!!!!!!!!!!

+

Vote Nucleus! The center of control!

VOTE NUCLEOLUS

VOTE NUCLEOLUS: the Brain of the Nucleus!

Here is a snippet of what a nucleus would look like without a nucleolus... 

What is the Nucleolus?

It is a round organelle located in the nucleus of a eukaryotic cell. It has no membrane surrounding it; it simply sits in the nucleus. 

-> A factory where the basic subunits for ribosomes to be created.

How it Works

The nucleolus creates ribonucleic acid, or RNA, which is rewritten and combined with proteins in order to create incomplete ribosomes.

RNA carries blueprint information from the DNA to control the synthesis of proteins.

Importance

Without the nucleolus creating incomplete ribosomes, the cell would not be able to complete its goal of creating proteins, since ribosomes are  an essential organelle for protein synthesis.

NO NUCLEOLUS = NO RIBOSOMES = NO PROTEINS = CELL ULTIMATELY FAILS AT LIFE

IN SHORT... RNA  is responsible for ensuring the future creation of proteins within the cell

BACKGROUND INFO

Principle Types of RNA Required for Protein Synthesis

mRNA (messenger RNA)  - carries copies of the genetic information from DNA since it is too precious too travel around the cell. It uses three-base code words that each specify a specific amino acid.

tRNA (transfer RNA) - essential for decoding the words in the mRNA. Each amino acid has its own type of tRNA, which binds it.

rRNA (ribosomal RNA) - associates with proteins to eventually create ribosomes. They catalyze the amino acids into protein chains and they bind tRNA’s with other essential molecules that are vital for protein 

synthesis.




DNA vs. RNA

- The legitimate blueprint of biological instructions for the functioning of a cell of a living organism - Found in mitochondria and nucleus - Double-stranded structure

- Carries the blueprint of the code of the DNA. It transfers these genetic instructions needed for the creation of the ribosome. - Found in nucleolus, cytoplasm and ribosome - Single-stranded structure

Nucleolus fun facts!

-> in certain viruses, the RNA carries the genetic information instead of the DNA

-> many species of cells contain many nucleoli in a single nucleus

-> the nucleolus disappears during mitosis

-> it is not surrounded by a membrane!

Vote Nucleolus... because you can't live without a brain

Golgi Apparatus

"The Processor"

VOTE GOLGI APPARATUS

_________________________________________________________

The Golgi apparatus (found primarily in animal cells) functions as the most important organelle within the cell. The Golgi processes and prepares vital proteins (forged by all those less important organelles) for serviceability and possible secretion.

_________________________________________________________

Heavy Lifter

The Golgi apparatus proves its importance by processing vital proteins that are extremely important for cell stability.  The Golgi modifies these proteins in such a way that they are usable by the rest of the cell, allowing it to function.

_________________________________________________________

How the Golgi Apparatus Operates

1. First, Golgi apparatus absorbs sack-like" objects or "vesicles" in the cis face that transport proteins from the ER into the Golgi body.
2. Then, proteins make their way through the medial sector of the Golgi stack, where most of the breaking down and modifying of the proteins are made.
3. Next, the proteins progress into the trans area of the Golgi, where they are "packaged" into transport vesicles, and "prepared for shipping," much like a distribution center.  
4. Finally, the proteins exit the Golgi apparatus via the trans face, moving to required parts of the cell that can now productively use these proteins.  The transport vesicles may also move beyond the cell membrane, carrying processed proteins to other cells that require the services that they provide.

HOW THE GOLGI WILL HELP YOU!

Ever really really really need something, but you don't have the right part to make it work?  

NOW YOU CAN!  

The Golgi apparatus seeks to assist all parts of the cell (no matter how unimportant they prove to be) by packaging their proteins and shipping them off for consumer usability.

TODAY'S MISSION:

Vote for Cytoplasm it will keep our community together

LITERALLY.

I am the most important organelle and I will be capable of keeping everyone TOGETHER! As Cytoplasm I am here to help every organelle stick together in a cell; in both animal and plant. I am here to help your needs and strive for the best of our cell communities. While working I will be able to…

• help the growth of new cells
• help different organelles stay in our cell
• help the movement and shape of our cell
• even help each organelle stay away from one another.

I am here to help you and if you vote for me we will have a great cell community.

 

HOW I WORK…

Through my time of work there is a lot that I strive to achieve.  I am known to take up the space in the community of a cell to make it strong and stay together. I have a great impact in many parts of the cells and movements. I take on a big part in mitosis. As well in the cells I bring protein, carbohydrates, salts, etc. to keep everything working and strong. My  motive is to keep everyone happy.
