Cellular Respiration

Definition

Cellular respiration is the process by which cells convert sugars into energy, helping to power all cellular functions.

Scientific / Technical Definition

Cellular respiration is a set of metabolic reactions and processes that occur in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products. This process typically involves glycolysis, the Krebs cycle, and the electron transport chain.

Benefits

• Provides energy to support cellular functions.
• Maintains metabolic balance.
• Supports muscle contraction and other vital processes.

Examples

• The breakdown of glucose in the presence of oxygen.
• Energy production in muscle cells during exercise.

Additional Information

• importance: Cellular respiration is crucial for sustaining the energy supply necessary for living organisms to perform essential functions.
