Imagine what you would see if you came upon a group of cats in the dark with their eerily glowing eyes; it is easy to see how the term glaring came to be yet one more name for a group of cats. A group of wild cats can be called a dout or a destruction -- no need to wonder how that word association came about. If anyone offers to let you play with their mischief of kittens, you may want to decline the opportunity. A group of rats is sometimes called a mischief.. Baby rats and mice are called pups or kittens. So a mischief of kittens would actually be a group of baby rats, not cuddly little felines, though the term mischievous would be an apt description for a group of cute little furballs.
Cellular respiration can be an anaerobic or aerobic respiration, depending on whether or not oxygen is present. Anaerobic respiration makes a total of 2 ATP. Aerobic respiration is much more efficient and can produce up to 36-38 ATP with a single molecule of glucose.
The amount of energy contributed by glycolysis differs depending on which electron carrier (NADH or FADH2) is used to span the mitochondrial membrane. That is why the amount of ATP produced by cellular respiration is estimated to be between 36 and 38 moles. Also: Biology textbooks often state that 38 ATP molecules can be made per oxidized glucose molecule during cellular respiration (2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system).
