Final answer:
During metabolic stress, the abundance of (+) and (-) acute phase proteins can change. Acute phase proteins are a group of proteins that are produced in response to inflammation or infection. In general, the levels of (+) acute phase proteins tend to increase during metabolic stress, while the levels of (-) acute phase proteins tend to decrease.
Step-by-step explanation:
During metabolic stress, the abundance of (+) and (-) acute phase proteins can change. Acute phase proteins are a group of proteins that are produced in response to inflammation or infection. In general, the levels of (+) acute phase proteins tend to increase during metabolic stress, while the levels of (-) acute phase proteins tend to decrease. This response helps the body to maintain homeostasis and combat stress.
