What is the first stage of cellular respiration?

Cellular Respiration

Cellular respiration refers to the process that converts sugars into energy for the body. When you eat food, you take in nutrients on a macro level, and then your body digests that food and turns those nutrients into energy - ATP - on a cellular level. There are three important stages in this process.

Answer and Explanation:

The first stage of cellular respiration is called glycolysis. Knowing that the prefix of this word is glycol-, we can assume this process is associated with glucose (sugar). The suffix -lysis in the field of biology refers to separation. Thus glycolysis means breaking down glucose. During glycolysis in cellular respiration, glucose is converted into pyruvate. Glycolysis requires glucose and ATP, but it does not require oxygen.
