Aerobic Respiration

Aerobic respiration is the process by which complete oxidation of respiratory substrate occurs. In this case, respiratory substrate glucose breaks down in the presence of oxygen resulting in the end products of CO2 and H2O. Most of the cells perform the respiration through aerobic process.Aerobic respiration occurs by completing the series of chemical reactions. It … Read more

Anaerobic Respiration and Its Application

Anaerobic respiration is the process by which incomplete oxidation of respiratory substrate takes place. In this case, it occurs in the absence of oxygen resulting the end products of ethyl alcohol and CO2 in plants and lactic acid (in animals) with very slight energy.  Anaerobic respiration is observed in certain bacteria, yeast and other fungi, … Read more

Respiration: Types and Significance

Respiration is basically an energy releasing and supplying process. It held in each cell of the plant. Its primary stages take place in the cytoplasm and secondary stages in mitochondria.Actually respiration is the set of the metabolic reactions and processes that take place in the cells of organisms to convert kinetic energy from nutrients into … Read more

Citric Acid Cycle: Krebs Cycle, Tricarboxylic acid cycle or TCA cycle

Citric acid cycle consists of number of reactions which produce NADH and FADHâ‚‚ and then they are used by the oxidative phosphorylation pathway to make ATP which then passes through the electron transport system. The citric acid cycle happens in the matrix of the mitochondria of the cell. The oxydation of pyruvic acid takes place … Read more

Glycolysis: Features, Steps and Significance

Glycolysis is the metabolic pathway where one molecule of glucose (C6H12O6) converts into pyruvic acid with the help of enzyme. Glycolysis occurs in the cytoplasm of the cell during both anaerobic and aerobic respiration. It is also known as EMP pathway i.e., Embden-Meyerhof-Parnas pathway named after German Biochemists Gustav Embden, Otto Meyerhof, and Jakub Karol … Read more

Comparison Among Auxin, Gibberellin and Cytokinin

Image of Comparison among Auxin, Gibberellin and Cytokinin

The following table shows the comparison among Auxin, Gibberellin and Cytokinin:AuxinGibberellinCytokininIt is an organic acid: Indole radicle-Auxin a(auxenotriolic acid): C18H32O5, auxin b(auxenolonic acid): C18H30O4 and hetero auxin(indole acetic acid): C10H9O2N.It is also organic acid-5-ringed diterpenoids. Its chemical formula is C19H22O6 (GA3).It is also an organic alkali: 6-furfuryl amino purine similar to adenine. Its chemical formula … Read more

Gibberellin and Cytokinin

GibberellinThe gibberellin is the plant hormone that contains diterpenoids organic acid and acts as growth regulator of the plants. The fungus Gibberella fujikuroi is responsible for fooling seedling disease or bakanae disease. Eiichi Kurosawa ( a Japanese scientist) first identified this disease in 1926. Later on, Tokyo University showed that this fungus Gibberella fujikuroi produces … Read more

Auxin and Its Functions

Auxin is a indole radicle plant hormone which is produced by growing tip of a coleoptile and influence growth rate of the cells and also encourages the length of roots and stems of plants.This type of hormone contains different types of organic acid. The plant hormone auxin and its role were first discovered by Frits … Read more

Photosynthesis: Definition, Process and Its Significance

image of Photosynthesis

All the living organism needs energy to perform their different normal metabolic functions. Food is the source of the power of the living body. Chlorophyll-containing plants produce foods by using solar energy. This particular function for creating their food is known as photosynthesis. French physiologist Henri Dutrochet (1837) first showed that the green parts of … Read more
