When the parts of the whole work or fit together well, they are cohesive, like a cohesive family whose members pitch in with everything from making dinner to painting the house. The adjective cohesive comes from the Latin word cohaerere, or âto cleave together.â Cohesive things stick together, so they are unified. A cohesive neighborhood's members get together to plan things like block parties, and they work together to solve problems.
Fermentation refers to catabolic processes where organic molecules, such as sugars or amino acids, are broken down to produce energy without the use of a membrane-bound electrâ¦on transport chain. Depending upon the organism, fermentation can occur in the presence (aerobic) and/or in the absence (anaerobic) of oxygen.
Anaerobic means without oxygen, and respiration refers to the processes in a cell that convert biochemical energy, such as that found in glucose, into usable energy in the form of ATP. Waste products like carbon dioxide are also produced during this process. The fermentation process in anaerobic respiration is roughly 5 percent as effective as what cells can do when they have access to oxygen. An aerobic cycle may produce between 36 and 38 ATP molecules, while anaerobic respiration only creates 2 ATP molecules.
