Enzymes function best at the normal pH level they were made to be in. Most work best at a neutral pH level (7), but some enzymes such as pepsin (located in the stomach) work best in very acidic pH levels. If the pH level becomes too acidic for the enzyme, it can lead to denaturing of the enzyme's active site.

Teratogens are drug or other agents that cause physical or functional bnormalities in fetuses that are exposed to such agents. A typical example is alcohol. The degree of the abnormality on the fetus depends on a number of factors which are:
- the type of agent
- the developmental stage of the fetus

- the concentration of teratogenic agent being exposed to
Answer:
a. The molecule is not lipid soluble b. The molecule is not derived from a series of steps beginning with cholesterol
Explanation:
All the steroid hormones have a four ring sterol nucleus in their structure. These hormones are soluble in lipids. Steroid hormones are produced by the pathways using cholesterol as the starting substance. Some of the examples of steroid hormones are aldosterone, calcitriol, estrogens, and progesterone. Therefore, if the given molecule is not soluble in lipids and is not derived from cholesterol, it cannot be a steroid hormone.
