The most accurate response is:

Cow proteins are broken down into smaller molecules, which then can be used to build human proteins.

When humans consume beef, the proteins from the cow are digested in the digestive system. Enzymes in the stomach and small intestine break these proteins down into smaller units called amino acids. These amino acids are then absorbed into the bloodstream and used by the body to synthesize human proteins, in accordance with the body's specific needs. The process does not involve using cow proteins directly; rather, it involves breaking them down into basic building blocks that can be reassembled into human proteins.
