Coffee bean rain is needed in the beginning of the season when the fruit is developing and less later in the season as it ripens. When the fruit is ripe, it is almost always handpicked, using either "selective picking", where only the ripe fruit is removed, or "strip-picking", where all of the fruit is removed from a limb all at once. This selective picking gives the growers reason to give their coffee a certain specification called "operation cherry red" (OCR). In rare circumstances, the Asian palm civet eats coffee berries and excretes the beans. These beans are called "kopi luwak", and can
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
