Differences regarding respiration:

Difference between respiration and breathing:

Breathing

Respiration
  1. It is step of respiration. Involves intake of O2 and out of Co2.
  1. It is physiological process which involves exchange of gases and oxidation of food.
  1. It is extracellular process.
  1. It is intracellular process.
  1. It does not release energy.
  1. It releases energy in the form of ATP.
  1. No enzymes are involved.
  1. Enzymes are involved.
  1. Its mechanism varies in different organisms.
  1. Its mechanism is same in all animals.

 

Difference between respiration and Combustion:

Combustion

Respiration

  1. Many bonds breaks at same time releasing large amount of energy at a time.
  1. Bonds breaks step by step so energy also releases step by step.
  1. Energy is lost as heat.
  1. Energy is stored as ATP.
  1. Enzymes are hot involved
  1. Enzymes involved
  1. Light also produced
  1. No light produced
  1. Temperature rises
  1. Temperature remains low
  1. Uncontrolled process
  1. Controlled process.

 

Difference between Photosynthesis and Respiration:

Photosynthesis 

Respiration

  1. It is an anabolic process.

O + O O.
  1. It is a catabolic process

O O + O
  1. Here glucose is formed by the use of simple inorganic molecules.
  1. Here glucose breaks into simple inorganic materials.
  1. Increase in weight.
  1. Decrease in weight
  1. Occurs in green leaves (parts) of Plants.
  1. Occurs in all cells of animals.
  1. Occurs in sunlight.
  1. Occurs at day and night.
  1. Plants can live for many days without it.
  1. Cells die soon without it.

 

Difference between aerobic and respiration:

 Anaerobic

Aerobic

  1. It does not involves environment oxygen.
  1. It uses oxygen.
  1. Co2 may or may not releases.
  1. Co2 always releases.
  1. Water is not produced.
  1. Water is also produced.
  1. Organic molecules are formed as end products.
  1. Inorganic molecules are produced as end products
  1. Occurs in some bacteria, yeast and parasites.
  1. It occurs in all plants and almost all animals.
  1. It provide only 5% 0f energy of glucose.
  1. It provide almost full energy of glucose
  1. Occurs in cytoplasm of cell only.
  1. Occurs in cytoplasm and mitochondria.
  1. Occurs in 2 steps:  glycolysis and incomplete breakdown of pyruvate.
  1. 5 steps: glycolysis, pyruvate oxidation TCA cycle, electron transport system and chemiosmotic ATP synthesis.
