![]() At the end of aerobic respiration CO 2 and H 2O is formed.Aerobic respiration takes place in nucleus as well as in cytoplasm.Oxygen is required for aerobic respiration.Meiosis takes place in only germinal cells.Meiosis is essential for formation of gametes in sexual reproduction.Genetic recombination takes place in homologous chromosomes as there is crossing over during prophase-I.Each is further subdivided into prophase, metaphase, anaphase and telophase. One cell gives rise to four daughter cells in meiosis.In meiosis, the chromosome number is reduced to half.Mitosis takes place both in somatic cells and germinal cells.Mitosis is essential for growth and development.Genetic recombination does not happen in mitosis as there is no crossing over.prophase, metaphase, anaphase and telophase. Karyokinesis of mitosis has four stages, viz.One cell gives rise to two daughter cells in mitosis.Diploid cells remain diploid, without change. In mitosis the chromosome number does not change.Two molecules of ATP are produced in TCA cycle.ATP molecules are not used up in TCA cycle.Pyruvate is converted into CO 2 and H 2O during TCA cycle.The second step in cellular respiration is TCA cycle.TCA cycle takes place only during aerobic respiration.In TCA cycle, molecule of acetyl-co-A is completely oxidized and in the process CO 2, H 2O, NADH 2, FADH 2 and ATP is produced. ![]() Four molecules of ATP are produced in glycolysis.Two molecules of ATP are used up in glycolysis.Two molecules of pyruvate are obtained in glycolysis.The first step in cellular respiration is glycolysis where glucose is converted into pyruvate.Glycolysis can take place in both aerobic and anaerobic respiration. ![]() In glycolysis, one molecule of glucose is oxidized step-by-step to produce two molecules each of pyruvic acid, ATP, NADH 2 and water.The process of glycolysis occurs in the cytoplasm of the cell.Glycolysis: The process occurring in the cell where a molecule of glucose is oxidized in step by step process forming two molecules of each of pyruvic acid, ATP, NADH 2 and water, is called glycolysis. Proteins: Protein is a macromolecule which is formed by many amino acids which are joined by peptide bonds.Ĭellular respiration: Oxidation of glucose and other food components which takes place inside the cell in presence or absence of oxygen, is known as cellular respiration.Īerobic respiration: Cellular respiration taking place in presence of oxygen is known as aerobic respiration. which are components of the food are called nutrients. Nutrients: The substances like carbohydrates, proteins, lipids, vitamins, minerals etc. Nutrition: The process of taking nutrients in the body and utilizing them by an organism is known as nutrition.
