Questions and Answers
What is Proteomics? Why is it important? - ANSWER✔✔-the study of the composition,
structure, functions and interactions of the proteins directing the activities of each living
cell. It is important is because proteins make up virtually everything and direct the
activity of cells.
Why are proteins essential in animals' diets? - ANSWER✔✔-they cannot synthesize all
of the amino acids needed and must obtain essential amino acids from food.
What are essential amino acids? - ANSWER✔✔-amino acids that cannot be synthesized
by an organism and must be obtained through diet.
What is arguably the most important function of cells? - ANSWER✔✔-the production of
the thousands of different proteins the body needs to function.
One of the key functions of some of the cellular proteins involves what? - ANSWER✔✔-
transport of nutrients and other materials in out of the cell.

, What is a cell and why is it important? - ANSWER✔✔-the basic structural, functional
and biological unit of all known living organisms. The smallest unit of life that can
replicate independently. Building blocks of life
Major components of a cell - ANSWER✔✔-Memebranous: Endoplasmic reticulum,
golgi apparatus, lysosomes, peroxisomes, mitochondria
Non Membranous: cytoskelaton, microvilli, centrioles, cilia, ribosomes, proteasomes
Tenets of cell theory - ANSWER✔✔-cells are the building blocks of all plants and
animals
all cells are produced by the division of pre-existing cells
Cells are the smallest units that perform all vital physiological functions
Each cell maintains homeostasis
Homeostasis at higher levels, reflects combined, coordinated action of many cells
What are the different structural levels of proteins? - ANSWER✔✔-Primary, secondary,
tertiary, quaternary
What are enzymes and why are they important? - ANSWER✔✔-The best known role of
protein inside the cell. They serve as a catalyst for chemical reactions. They are highly
specific and accelerate chemical reactions in metabolism and DNA manipulation.
