Step-by-step explanation:
When people eat beef, they do consume cow proteins. However, the human digestive system is capable of breaking down and utilizing proteins from various sources, including cows.
Proteins are made up of amino acids, and although there are differences in the specific amino acids found in cow and human proteins, they are still similar enough that the human body can digest and use them. In fact, beef is considered a good source of protein for humans.
It is worth noting that some individuals may have allergies or sensitivities to certain proteins found in beef or other animal products. In these cases, it is important to avoid consuming those specific proteins to prevent adverse reactions.
Overall, the human body is able to digest and utilize the proteins found in beef, despite differences between cow and human proteins.
