During cooking, what effect does heat have on proteins found in foods such as meat and eggs?

Proteins dissolve completely, creating a smoother texture.
Proteins become more elastic and expand in size.
Proteins firm up, shrink, and lose water. (correct)
Proteins break down into simple sugars, enhancing sweetness.

How do acids contribute to the cooking process of proteins, particularly in tougher cuts of meat?

Acids neutralize the flavors, requiring more seasoning.
Acids toughen the connective tissue, requiring longer cooking times.
Acids help tenderize the meat and quicken the protein firming process. (correct)
Acids increase the water content within the protein.
