Cells do not use the energy from oxidation reactions as soon as it is released. Instead, they convert it into small, energy-rich molecules such as ATP and nicotinamide adenine dinucleotide (NADH), which can be used throughout the cell to power metabolism and construct new cellular components.
Another difference is that deer antlers are branched and antelope horns are not. Antelopes belong to family Bovidae (as do sheep, goat and cattle), while deer belong to family Cervidae. Both are even-toed ungulates (hoofed animals) and ruminant mammals.
Appearance. Sheep have a thicker, fuller coat that needs to be sheared and is the source of wool. Goats can also be sheered to produce mohair and cashmere. Most goats have horns, but sheep do not. Sheep and goats have different mouths -- sheep have an upper lip with a division in it called a philtrum, but goats don't.heep and goats are both small livestock animals raised for their wool, hair or pelts as well as milk and meat. Sheep and goats were the first animals that humans domesticated, and they continue to be among the most popular livestock animals.
