Tutorial

What's Covered

Welcome to today’s lesson on mitochondria. In this lesson today, you will be learning about the structure and function of the mitochondria. Specifically you will learn:

  1. What are Mitochondria?
  2. ATP
  3. Cellular Respiration

1. What are Mitochondria?

Mitochondria are cellular organelles found within eukaryotic cells. Eukaryotic cells are cells that contain a nucleus, such as our cells, for example. Mitochondria are oftentimes described as the powerhouse of the cell, which means is that they're the place in the cell where energy is made.

Term to Know

Mitochondria

An organelle found inside cells that produces energy in the form of ATP


2. ATP

Mitochondria are the site of ATP production. ATP stands for adenosine triphosphate, and this is basically an energy storage molecule produced by cells for cells to carry out their normal functions.

Term to Know

ATP

A molecule that is used inside cells as a source of energy

Cells need some sort of energy to power the cell, so mitochondria are called the powerhouse of the cell because they are the place where ATP production occurs. This ATP energy is made through a process called cellular respiration.


3. Cellular Respiration

The process called cellular respiration is what occurs in order for ATP to be made.

Term to Know

Cellular Respiration

A process that converts organic molecules into energy in the form of ATP

Cellular respiration actually has three phases associated with it.

1. Glycolysis

A phase of cellular respiration that happens in the cytoplasm to make ATP for the cell.

2. Krebs Cycle

A phase of cellular respiration that occurs within mitochondria.

3. The Electron Transport Chain

A phase of cellular respiration that occurs in the mitochondria; often this is referred to as ETC.


Summary

So, this lesson has been an overview of the mitochondria. The mitochondria is composed of inner and outer membranes. You also learned that ATP production occurs in the inner membrane. Finally, you learned about the three phases of cellular respiration, which produce ATP for the cell.

Keep up the learning and have a great day!
