During the ebb response, what happens to plasma insulin?

During the ebb response, what happens to plasma insulin?

• A. Low
• B. Elevated
• C. Normal
• D. Fluctuating

Answer: (A)

During the ebb response the body is in a shocked, hypoperfused state with reduced metabolic activity. The hormonal environment is dominated by counter-regulatory hormones such as epinephrine, cortisol, and glucagon, which drive glucose production to preserve essential brain and organ function. This milieu also suppresses insulin secretion and lowers insulin action, so plasma insulin levels are typically low even as blood glucose may be high. This combination contrasts with later phases where insulin rises to support anabolic processes.
