I just answered this question on USATEST PREP and got it right.
2-sensitive to pH and temperature of their environment
4-large proteins with a special surface pattern
They include the temperature and the pH value.
Each enzyme has a temperature range and pH range that makes them has the quickest action, they're called the optimum temperature and pH. Each optimum temperature and pH is different for each enzymes.
For example, the enzyme in our stomach has a optimum temperature of human temperature range, and a optimum pH for 2.0
However, if the temperature is too low or the pH value is too extreme, the enzyme may denature. The enzyme can no longer work to digests any substrate.

The <u>adrenal gland</u> releases a torrent of hormones, such as epinephrine and norepinephrine as the fight or flight response when a person is stressed or scared.
<h3>What are adrenal glands?</h3>
The adrenal glands are two small organs responsible for secreting hormones such as cortisol, adrenaline or noradrenaline into the bloodstream.
<h3>Characteristics of adrenal glands</h3>
- They are responsible for producing hormones that help regulate metabolism, the immune system, blood pressure, the response to stress and other essential functions.
- The main hormones secreted by the adrenal medulla include epinephrine (adrenaline) and norepinephrine (noradrenaline), which initiate the fight or flight response.
Therefore, we can conclude that the adrenal glands release certain hormones in response to stress, some of which are vital for survival.
