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.
Since variations in climate exist, it follows that God would provide animals the ability to adapt so this could be accomplished. Both biblical and hybrid data indicate that sheep (Ovis aries) and goats (Capra hircus) belong to a monobaramin (or basic type, a group belonging to the same kind).
