<span>Pepsin is an enzyme that breaks down proteins into amino acids in the stomach (where the pH is 1-3). Pepsin needs to be in an acidic environment to be activated. The optimum temperature is between 30 oC and 40 oC because the average human body temperature is 37 oC. The optimum pH is the acidic one because your stomach has an acidic pH.</span>
What is part B I need more info.
<u>Answer:</u>
<em>ATP is used for immediate energy and short-term storage, while starch molecules are stable and can be stored for a long time.</em>
<u>Explanation:</u>
Starch and ATP can both be described as molecules that store energy. ATP is used for <em>immediate energy and short-term storage,</em> while starch molecules are stable and can be stored for a long time.
ATP is known as an <em>energy medium for a reason</em> does changes into energy. In this process starch does have to pass through various steps and series to convert into energy.
<em>Plants use starch for a very important purpose which is to store glucose.</em>
