Steroids are classes of lipids that include cholesterol, sex hormones, and cortisone. steroids are not hydrocarbon chains like triglycerides, but instead contain four fused carbon rings. although steroids can bond to fatty acids, steroid molecules do not contain a fatty acid chain, and the monomer of a steroid biomolecule is difficult to define. which of these does not correctly pair a steroid and its function?
a) cholesterol is an energy source.
b) cholesterol decreases cell membrane fluidity.
c) estrogen contributes to the development and maintenance of female secondary sex characteristics.
d) cortisol can control blood sugar levels, regulate metabolism, reduce inflammation, and assist with memory formulation.

A

Explanation:

Cholesterol is not an energy source in the body. It is used to make Vitamin D, and hormones such as cortisol, estrogen, and progesterone, and digestive fluids like bile.

Cholesterol increases membrane fluidity, especially at lower temperatures when the cell membrane would freeze. This is because the molecule intercalates between the fatty acid chains of the lipid layer of the cell membrane. This prevents the lipids from packing tightly together which would cause the membrane to be rigid. However, it does decrease membrane fluidity at high temperatures preventing the cell membrane from melting at temperature that is higher than its melting point.

humans, along with other animals and plants, have linear chromosomes that are arranged in pairs within the nucleus of the cell. the only human cells that do not contain pairs of chromosomes are reproductive cells, or gametes, which carry just one copy of each chromosome.
