Originally run by local Chinese people, they can be found in many residential areas. Old-fashioned kopitiams are usually located at shop houses, and often have a quite run-down appearance. The term kedai kopi or warkop (which stands for warung kopi) is more often used. More recently, modern kopitiams have emerged, and can be found in many shopping malls, particularly in big cities such as Jakarta, Medan, Batam and Surabaya. These attract
Cellular waste product as well as by cells called anaerobes that selectively perform anaerobic respiration even in the presence of oxygen. In anaerobic respiration, weak oxidants like sulfate and nitrate serve as oxidants in the place of oxygen. Generally, in anaerobic respiration sugars are broken down into carbon dioxide and other waste products that are dictated by the oxidant the cell uses. Whereas in aerobic respiration the oxidant is always oxygen, in anaerobic respiration it varies. Each oxidant produces a different waste product, such as nitrite, succinate, sulfide, methane, and acetate. Anaerobic respiration is correspondingly less efficient than aerobic respiration. In the absence
