Kopi Luwak aromatic civet coffee spread from locals to Dutch plantation owners and soon became their favourite, yet because of its rarity and unusual process, the civet coffee was expensive even during the colonial era. "Kopi" is the Indonesian word for coffee. "Luwak" is a local name of the Asian palm civet in Sumatra. Palm civets are primarily frugivorous, feeding on berries and pulpy fruits such as figs and palms. Civets also eat small vertebrates, insects, ripe fruits and seeds. Producers of the coffee beans argue that the process may improve coffee through two mechanisms, selection and digestion. Selection occurs as the
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
