The correct answer is cholesterol.
To arrive at this answer, we can break down the question to identify the key concepts. We are looking for two things: the components of cell membranes and a substance used to create hormones.
To answer the first part, we need to understand the composition of cell membranes. Cell membranes consist of a phospholipid bilayer. Phospholipids are made up of two fatty acid chains (which are hydrocarbons) and a phosphate group. However, the question specifically asks for a single answer worth 1 point, so we should look for a more general term that encompasses the entire composition of the cell membrane.
Cholesterol is a key component of cell membranes. It is a type of lipid that helps maintain the fluidity and stability of the membranes. Therefore, cholesterol is the correct answer for what makes up cell membranes.
For the second part of the question, the substance used to create hormones, we can eliminate options like hydrocarbon, starch, and glucose, as they are not directly involved in hormone synthesis. Cholesterol, on the other hand, is a precursor molecule used to synthesize various hormones, including the steroid hormones produced in the adrenal glands and reproductive organs.
Therefore, the correct answer is cholesterol.
