water. . . Anaerobic respiration Anaerobic respiration takes place without oxygen.
Glucose is converted into ethanol (Ethanol fermentation by yeast) or lactic acid (lactic acid fermentation by bacteria). C H O → 2CO + 2C H OH + Energy (ATP) . . Respiratory quotient (R.Q) Respiratory quotient is the ratio of volume of carbon dioxide liberated and the volume of oxygen consumed during respiration.
It is expressed as RQ = Volume of CO liberated Volume of O consumed Points to Remember Tissue is a group of similar or dissimilar cells, having a common orgin and performing similar functions. Plants are capable of synthesizing glucose from CO and H O in the presence of light, by the process of photosynthesis. Light reaction takes place in grana of chloroplast. Dark reaction takes place in stroma of chloroplast.
Respiration involves both external and cellular respiration. Aerobic respiration takes place in the presence of oxygen. Aerobic respiration occurs in three major steps like Glycolysis, Krebs cycle and Electron transport chain. I.
