The correct answer is cholesterol, which makes up cell membranes and is also used to create hormones.

To determine this answer, you can break down the question and consider each option.

1. Glucose: Glucose is a type of sugar that is used as an energy source in cells. While it is an important component of cellular metabolism, it is not the main component of cell membranes or involved in hormone production. So, this is not the correct answer.

2. Starch: Starch is a complex carbohydrate that serves as a storage form of glucose in plants. It does not directly contribute to cell membranes or hormone creation in animals. Therefore, this is not the correct answer.

3. Cholesterol: Cholesterol is a lipid molecule that is a crucial component of cell membranes. It helps to maintain the structural integrity and fluidity of the membrane. Additionally, cholesterol is a precursor molecule for the synthesis of various hormones, including steroid hormones. Therefore, cholesterol is the correct answer.

4. Hydrocarbon: A hydrocarbon is a compound consisting of only hydrogen and carbon atoms. While certain hydrocarbons can be components of some lipids and hormones, the term itself is not specific enough to be the correct answer.

In summary, out of the given options, the correct answer is cholesterol, which is a major component of cell membranes and is involved in the production of hormones.
