Explore mitochondria, the powerhouses of the cell, and cellular respiration in this 6th Grade Science activity on ATP production.
Energy Factories: The Mitochondria Challenge
Every living thing is made of cells, and every cell needs energy to stay alive. Inside your cells are specialized structures called mitochondria that act like tiny power plants, often called the powerhouses of the cell. By studying how these organelles are built, we can understand how they produce the fuel your body needs for everything from breathing to sprinting. Use the information below to investigate the inner workings of the mitochondrion.
Mitochondria are special parts inside a cell because they have two layers. The outer membrane (layer) acts like a skin that holds everything together. The inner membrane has many deep folds that look like wavy lines. These wavy shapes give the cell much more surface area (space) to work in a tiny area. Having more space is important because it lets the cell make more energy for your body to use.
The main job of these parts is converting food into a type of power called ATP. This usable energy is what your body needs to grow and move. The whole process of making this power is called cellular respiration . Because the inner layers have so many bends, the cell has more room to finish these tasks quickly. A cell with many wavy layers can create a source of power much faster than one without them.
The middle of the organelle is a liquid area filled with enzymes. These tiny helpers start the first steps of making power from nutrients you eat. Some parts of your body, like your heart or legs, need a constant supply of power to keep working. Because of this, those cells possess many more of these power centers to keep up with the work. These tiny parts make sure every cell has the fuel it needs to stay alive.
