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.
Deer, Moose, Carriboe, and elk have antlers and they shed them. Antelopes have horns which do not shed. In terms of evolutionary relationships, deer and antelope are not the closest relatives of one another. Antelopes are classified as bovids, and they are basically any bovids that are not cattle, goats, or buffalo.
