Respiration releases energy for use in life processes. There are two types of respiration, aerobic (uses oxygen) and anaerobic (does not use oxygen). Respiration can produce useful products that have uses in a range of industries.

Energy from respiration

Glucose is produced during photosynthesis. This energy is released from cells by a series of chemical reactions. This process is called respiration. Energy from respiration is used in reactions that produce different molecules. Examples of these molecules include starch and cellulose, which are polymers of glucose required by plant cells.
