Asian palm civet digestive juices enter into the beans and modify the micro-structural properties of these beans. Proteolytic enzymes cause substantial breakdown of storage proteins. Kopi Luwak is traditionally made from the faeces of wild civets, however, due to it becoming a trendy drink, civets are being increasingly captured from the wild and fed coffee beans to mass-produce this blend. Many of these civets are housed in battery cage systems which have been criticised on animal welfare grounds. The impact of the demand for this fashionable coffee on wild palm civet populations is yet unknown but may constitute a significant threat. In Indonesia,
Cellular waste product Cellular waste product Cellular waste products are formed as a by-product of cellular respiration, a series of processes and reactions that generate energy for the cell, in the form of ATP. Two examples of cellular respiration creating cellular waste products are aerobic respiration and anaerobic respiration. Each pathway generates different waste products. When in the presence of oxygen, cells use aerobic respiration to obtain energy from glucose molecules. Simplified Theoretical Reaction: CHO + 6O → 6CO + 6HO + ~ 30ATP Cells undergoing aerobic respiration produce 6 molecules of carbon dioxide, 6 molecules of water, and up to 30 molecules
