Respiration is a mechanical process, while cellular respiration involves biochemical reactions through enzymatic action. Respiration is broadly classified into two types: external and internal; cellular respiration consu... More » Science Biology

Cellular respiration produces molecules of adenosine triphosphate, or ATP, an organic compound composed of adenine, the sugar ribose and three phosphate groups. ATP is a high-energy molecule that cells use to drive many ... More » Science Biology Cells

In chronological order, the four steps of cellular respiration are glycolysis, a transition reaction, the Krebs Cycle and an electron transport chain. Cellular respiration occurs in the cytoplasm and in the mitochondria. More »

Cellular respiration produces six carbon dioxide molecules, six water molecules and 38 molecules of adenosine triphosphate, or ATP, for every molecule of glucose. This process occurs in four stages: glycolysis, the trans... More » Science Biology

Cellular respiration is performed by living cells in every variety of organism. It involves the production of an energy source within cells to be used as fuel for biological processes. More »

Anaerobic bacteria are not likely to carry out cellular respiration. Cellular respiration requires oxygen, and anaerobic bacteria are able to survive in environments that lack oxygen. More » Science Biology

Aerobic cellular respiration rates vary according to three main factors: the amount of nutrients available to the cell, the specific type of cell and the ambient temperature. All three factors affect the rate at which re... More »
