of Life—Fueled by Nutrients
PURPOSE AND PERSPECTIVE OF THE CHAPTER
The purpose of this chapter is to highlight the cell as the fundamental structural and functional unit of
human life, emphasizing its role as a dynamic system fueled by nutrients. The chapter introduces the
structure and function of eukaryotic cells, detailing major cellular components such as the plasma
membrane, cytoskeleton, mitochondria, nucleus, endoplasmic reticulum, Golgi apparatus, lysosomes, and
peroxisomes. It explains how these structures interact to maintain cellular integrity, regulate
communication, and support metabolic processes essential for life.
From a nutrition and metabolism perspective, the chapter highlights how nutrients influence cellular
energy production (ATP synthesis), DNA replication, gene expression, enzymatic activity, and cellular
signaling. It connects molecular biology to nutritional factors, demonstrating how vitamins and minerals
support DNA maintenance, chromatin structure, oxidative protection, and overall cellular health.
CHAPTER OBJECTIVES
The following objectives are addressed in this chapter:
1.1 Identify cellular components and their functions.
1.2 Describe the roles of cell receptors and enzymes.
1.3 Explain the mechanisms by which enzymatic reactions are regulated.
1.4 Discuss the need for and pathways involved in apoptosis.
1.5 Describe how energy is released and utilized in chemical reactions.

KEY TERMS
Activation energy: energy introduced into reactant molecules to activate them to the transition state
so that an exothermic reaction can take place
Allele: a copy of a particular gene inherited from a parent
Anticodon: three-base sequence of nucleotides within transfer RNA molecules
Apoptosis: an organized series of events that, once triggered, leads to cell death
Autophagy: breakdown or digestion of the body’s proteins, such as those found in the blood or within
cells
Caspases: a family of cysteine proteases involved in the degradative events during apoptosis (cell
death)
Catabolism: the process by which organic molecules are broken down
Cells: basic units of all organisms that arise from preexisting cells
Codons: three-base sequence in DNA or messenger RNA molecule that specifies the location of a
single, particular amino acid in a polypeptide chain
Complementary base pairing: pairing of nucleotide bases in two strands of nucleic acids; A pairs
with T or U, while G pairs with C
Cytochromes: heme-containing proteins that serve as electron carriers (e.g., in oxidative
phosphorylation or the cytochrome P450 system)
Cytokine: a generic term for nonantibody protein messengers released from a macrophage or
lymphocyte that are part of an intracellular immune response
Cytoskeleton: microtubules and microfilaments in a cell that provide internal reinforcement and
communication
Cytosol (Cytoplasm): a continuous aqueous solution of the cell and the organelles contained in it
Elongation: (1) extension of the polypeptide chain of the protein product during protein synthesis; (2)
addition of carbons (in two-carbon increments) to a fatty acid chain
Endoplasmic Reticulum (ER): a network of membranous channels pervading the cytosol and
providing continuity between the nuclear envelope, the Golgi apparatus, and the plasma membrane

Endothermic: a reaction in which the products have more free energy than the reactants and therefore
requires energy

Eukaryotic cells: cells with a defined nucleus surrounded by a nuclear membrane
Exons: segments of a gene that code for a sequence of nucleotides in a specific molecule of messenger
RNA

give off energy as heat
Free energy: potential energy inherent in the chemical bonds of nutrients
Genome: the sum of all the chromosomal genes of a cell

1
neutral) often abbreviated as H2
