1. Breathing: Taking in air rich in oxygen (inhalation) and giving out air rich in carbon dioxide (exhalation) using respiratory system is called breathing. 2. Cellular Respiration: The process of breakdown of food in the cells with the release of energy is called cellular respiration.

Cellular respiration uses energy in glucose to make ATP. Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. In glycolysis, glucose is split into two molecules of pyruvate. This results in a net gain of two ATP molecules.

The reactions of cellular respiration can be grouped into three main stages and an intermediate stage: glycolysis, Transformation of pyruvate, the Krebs cycle (also called the citric acid cycle), and Oxidative Phosphorylation.

Breathing involves two man steps, viz. inhalation and exhalation. During inhalation, we breathe in air which is rich in oxygen. During exhalation, we breathe out air which is rich in carbon dioxide.

An important similarity between photosynthesis and cellular respiration is that both processes involve a chemical reaction where an energy source is taken and transformed into a resultant product.

The main function of cellular respiration is to break down glucose to form energy. What is cellular respiration in simple terms? Cellular respiration can be defined simply as a series of metabolic processes that take place within a cell.

Cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.

If cellular respiration stops, a cell dies because if cellular respiration ceases, the cell will switch to using pyruvate or a pyruvate-derived…

Without respiration, plants would use up all the CO2 and starve to death. Photosynthesis requires the products from respiration, and respiration requires the products from photosynthesis.
