Carbon dioxide (chemical formula CO 2) is a colorless gas with a density about 60% higher than that of dry air. Carbon dioxide consists of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace current concentration is about % ( ppm) by volume, having risen from pre-industrial levels of ppm.E number: E (preservatives). Andrew B Lumb MB BS FRCA, in Nunn's Applied Respiratory Physiology (Eighth Edition), Carbon dioxide is the end product of aerobic metabolism and is produced almost entirely in the mitochondria where the P co 2 is highest. From its point of origin, there are a series of partial pressure gradients as carbon dioxide passes through the cytoplasm and the extracellular fluid . Gaseous signaling molecules as gasotransmitters. Gasotransmitters is a subfamily of endogenous molecules of gases or gaseous signaling molecules, including NO, CO, H 2 S. These particular gases share many common features in their production and function but carry on their tasks in unique ways, which differ from classical signaling molecules, in the human body. Chemistry Experiment: Production of Carbon Dioxide: Carbon dioxide is a naturally occurring chemical compound composed of 2 oxygen atoms each covalently double bonded to a single carbon atom.

• The lungs and heart have to work harder to supply the extra oxygen and remove the carbon dioxide. • Your breathing rate increases and you breathe more deeply. Heart rate also increases in order to transport the oxygenated blood to the muscles. • Muscle cell respiration increases - more oxygen is used up and levels of carbon dioxide rise. Variation in Fruit Weight and Yield.

During plant tissue culture growth sucrose acts as a fuel source for sustaining photomixotrophic metabolism (organisms can use different sources of energy and carbon), ensuring optimal development, although other important roles such as carbon precursor or signaling metabolite have more recently been highlighted. Sucrose is a very important part of nutrient medium as . Carbon dioxide is waste product. It must be excreted out from the body. Carbon dioxide is carried by the blood from the tissues to the lungs in three forms. 1. Physical solution: A very small amount of carbon dioxide (about 7%) dissolves in the plasma and is carried as physical solution/5(18). The hydration of carbon dioxide is a slow process but occurs rapidly in the red blood cells because a high concentration of the enzyme carbonic anhydrase catalyzes the reaction. Bicarbonate diffuses out of the red blood cells into the plasma in .
