Cellular Respiration
The process cells use to convert glucose into usable energy (ATP).
Also: aerobic respiration
Definition
Cellular respiration is the metabolic process by which cells break down glucose and other organic molecules in the presence of oxygen to produce ATP (adenosine triphosphate), carbon dioxide, and water. It occurs in three main stages: glycolysis in the cytoplasm, the Krebs cycle in the mitochondrial matrix, and oxidative phosphorylation in the inner mitochondrial membrane. A single glucose molecule can yield up to 38 ATP molecules.
Example
“During intense exercise, your muscle cells consume oxygen and glucose at high rates through cellular respiration to produce the ATP needed to power muscle contractions.”
Usage Examples
- 1
“The team applied cellular respiration best practices to improve their biology outcomes significantly.”
- 2
“Understanding cellular respiration is essential for anyone building a career in STEM.”
When & How to Use
Use 'Cellular Respiration' when working in Biology contexts where cellular respiration is the metabolic process by which cells break down glucose and other organic molecules in the presence of oxygen to produce atp (adenosine triphosphate), carbon dioxide, and water.
- ▸Applying cellular respiration principles during a biology project or initiative
- ▸Explaining cellular respiration to a junior team member or stakeholder unfamiliar with STEM
- ▸Evaluating options or proposals using cellular respiration as a decision-making criterion
Etymology & Origin
The term 'Cellular Respiration' derives from Latin roots and entered STEM professional usage as the field formalised in the 20th century.
History & Evolution
The concept of cellular respiration has evolved alongside STEM. Early practitioners relied on informal methods; structured approaches emerged with the professionalisation of biology in the mid-20th century. Today, cellular respiration is a standard part of STEM practice globally.
