What are the functional characteristics and structural arrangements of the biomolecules found inside a living cell? Illustrate their chemical structures.

Why should it make sense that a mitochondrion(a cellular organelle) is larger than a phospholipid molecule?

Which four kinds of atoms are most abundant in the body?

Lipids are a class of macromolecules that can be found in which of the following places? a) lipids can be found in all of these places b) in hormones such as testosterone  c) in the plasma membrane of cells  d) surround organs

All of the following are examples of the four major elements contributing to body mass except:  a) sulfur b) hydrogen  c) carbon  d) oxygen

Samples of illicit “street” drugs often contain an inactive component, such as ascorbic acid (vitamin C). After obtaining a sample of cocaine, government chemists calculate the mass of vitamin C per gram of drug sample, and use it to track the drug’s distribution. For example, if different samples of cocaine obtained on the streets of New York, Los Angeles, and Paris all contain 0.6384 g of vitamin C per gram of sample, they very likely come from a common source. Do these street samples consist of a compound, element, or mixture? Explain.

what are the specialized macromolecules and their specific functions within a living organism.
