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.
by Ricahrd Ochenfels AZ Game & Fish. Description: Pronghorn antelope are only found in North America. They are often referred to as antelope, however, they are not closely related to any African antelope species. The scientific name originates from Antilo =antelope and capra =goat, thus antelope-goat.
