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.
Castrated males are wethers. Goat meat from younger animals is called kid or cabrito (Spanish), and from older animals is simply known as goat or sometimes called chevon (French), or in some areas  mutton  (which more often refers to adult sheep meat).oats are among the earliest animals domesticated by humans. The most recent genetic analysis confirms the archaeological evidence that the wild Bezoar ibex of the Zagros Mountains are the likely origin of almost all domestic goats today.
