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.
An antelope is a member of a number of even-toed ungulate species indigenous to various regions in Africa and Eurasia. Antelopes comprise a wastebasket taxon (miscellaneous group) within the family Bovidae, encompassing those Old World species that are not cattle, sheep, buffalo, bison, or goats.
