The two main chemicals released during the "light-or -llight response" (or"acute stress response") include: adrenaline and cortisol adrenaline and carbohydratos carbohydrates and selenium cortisol and selenium

## Step 1<br />The "light-or-flight response", also known as the "acute stress response", is a physiological reaction that occurs in response to a perceived harmful event, attack, or threat to survival. This response is primarily mediated by the adrenal glands, which release certain chemicals to prepare the body for a potential threat.<br /><br />## Step 2<br />The two main chemicals released during this response are adrenaline (also known as epinephrine) and cortisol. Adrenaline is responsible for the immediate reactions, such as increased heart rate and blood pressure, preparing the body for a quick response. Cortisol, on the other hand, is a steroid hormone that helps the body manage stress and maintain homeostasis.<br /><br />## Step 3<br />The other options provided, such as "adrenaline and carbohydrates", "carbohydrates and selenium", and "cortisol and selenium", are not the primary chemicals released during the "light-or-flight response". Carbohydrates and selenium are not hormones and do not play a direct role in the acute stress response.
