When we eat food cellular respiration in our bodies breaks down the food and releases energy. In eukaryotes, this process takes place in the __ and __ in prokaryotes, such as bacteria, __ not have organelles, so respiration __ not occur in the mitochondria.

## Step 1<br />The problem is about cellular respiration, a process that breaks down food to release energy. This process is essential for all living organisms as it provides the energy needed for various cellular activities.<br /><br />## Step 2<br />In eukaryotic organisms, such as animals and plants, cellular respiration takes place in the mitochondria. The mitochondria are often referred to as the "powerhouse" of the cell because they produce ATP (adenosine triphosphate), the cell's main energy currency.<br /><br />## Step 3<br />On the other hand, prokaryotic organisms, such as bacteria, do not have mitochondria. Instead, they carry out cellular respiration in the cytoplasm of the cell.
