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.
There are only four species of antelope found in India, Black Buck,Chinkara Gazelle,Nilgai and Four Horned Antelope. The Goat-antelope is a sub species of antelope, Other grazing wild animals are species of deer such as sambhar,chital and barasingha. Antelopes are different then deer and Gazelle, all species of antelope have pointed hollow and permanent horns, while deer have branched and their antlers shed annually.
