What happens in the mitochondria?
In this video I would like to talk about what happens in the mitochondria.
The mitochondria is often called in school the powerhouse of the cell. It is a structure in the cell that generates ATP which is converted into energy. Think of the mitochondria as the charging station for your cell phone. Without any power your cell phone is not very helpful.
A mitochondria looks almost like a small cell inside a cell. It has ribosomes and dna. It has the ability to duplicate.
The mitochondria has two layers, an inner membrane and an outer membrane, the matrix, and the intermembrane space.
Cellular respiration requires sugar and oxygen in order to create ATP
First, the sugar in the form of glucose is converted into two pyruvates in a process called glycolysis This occurs outside the mitochondria and produces 2 ATP
The pyruvate which earlier was sugar travels into the mitochondria and more specifically the matrix.
At this location the pyruvate helps power the krebs cycle
During this process carbon dioxide is given off and NADH and FADH2 are formed and 2 molecules of ATP
Now we move to the step in which oxygen is used.Inside the inner wall are protein pumps.
NADH and FADH2 provide energy for these pumps and hydrogen ions flow back and forth through the protein pumps and generate 34 ATP.
This is called the electron transport chain.
The waste products from powering the electron transport chain protein pumps combine with oxygen to produce water molecules.
