Respiration in Plants Test - 1

Glycolysis" means the splitting of glucose. The first step of the process occurs in the cytoplasm of the cell and yields a small amount of energy (measured in units of ATP) and two molecules of pyruvate.

The other steps occur in the mitochondria.

It is an ongoing process as your cells have a constant need for energy

Glycolysis involves the breaking down of a sugar (generally glucose, although fructose and other sugars may be used) into more manageable compounds in order to produce energy. The net end products of glycolysis are two Pyruvate, two NADH, and two ATP

Fermentation is an anaerobic breakdown of carbohydrates in which an organic molecule is the final electron acceptor. It does not involve an electron transport system.

Furthermore,: it is a partial breakdown of glucose giving a little energy, 2 net ATP's per glucose by way of substrate-level phosphorylation.

The complete combustion of glucose, which produces carbon dioxide and water as end products, yields energy most of which is given out as heat.

Lactate dehydrogenase: (LDH) An enzyme that catalyzes the conversion of lactate to pyruvate When oxygen is inadequate for cellular respiration.

This is an important step in energy production in cells. Many different types of cells in the body contain this enzyme. Some of the organs relatively rich in LDH are the heart, kidney, liver, and muscle.

The scheme of glycolysis was given by Gustav Embden, Otto Meyerhof, and J. Parnas, and is often referred to as the EMP pathway.

Plants unlike animals have no special systems for breathing or gaseous exchange. Stomata and lenticels allow gaseous exchange by diffusion.
