Question

DNA is the blueprint not only for the organism but for all the parts of the cell. How does DNA dictate the functions of a particular cell (by the production of proteins)? But how does a cell produce proteins? This week, we'll discuss how DNA functions as a blueprint for the cell by looking at the relationship between genes and proteins, but we have to crawl before we walk. Let's begin by taking a close look at the cell, identifying all cellular organelles along with their roles in the cell.

This week, we're exploring the amazing and unique properties of cells! Cells are truly more than the sum of their parts. Scientists can add all the necessary ingredients to make a cell to in test tube, but no one has ever succeeded in making a living cell.

We'll start our discussion by making a running list of the organelles and their functions. By the end of the week, we'll have a complete picture of the cell's machinery.

The first student to post should pick an organelle and describe its structure and function. The next student should summarize the first student's organelle info and then add their own to the list. The third student will copy that list and add his or her own organelle description. Pass it on!

Answer 1

Answer:

Pick an Cellular organelle and describe its structure and function:

Mitochondria:

• Mitochondria are double membrane organelle and are considered the powerhouse of the cell because these organelle are involved in producing cellular energy. These organelles are essential for aerobic respiration process of eukaryotic cells. Mitchondria take nutrients and break them down to produce energy for the cell.
• Mitochondria consists of two membranes: Outer membrane and Inner membrane
• The inner membrane is folded with layers (known as cristae) that provides an increase in surface area and helps in the attachment of enzyme involved in the respiration process.
• The space between inner membrane and outer membrane is known as intermembrane space.
• Mitochondria contains around 65-70% protein (enzymes like monoamine oxidase, fatty acid Co ligase, adenylate kinase etc), 25-30% lipids and small amount of DNA and RNA.
• Mitochondria play a critical role in different cellular functions like oxidation, oxidative phosphorylation respiration.
• Mitochondria store energy for the cellular requirement in the form of ATP (Adenosine triphosphate)
