Chapter 1 - The Foundations of Biochemistry || with 100%
Errorless Solutions.
Biochemistry is... correct answers - The study of life at the molecular level
- the application of the principles of chemistry to explain biology
- the common sets of reactions and principles that underlie all living organisms
Living organisms have... correct answers - a high degree of chemical complexity and
microscopic organization
- systems for extracting, transforming, and using energy from the environment
- defined functions for each of the organisms components and regulated interactions among them
- mechanism for sensing and responding to alterations in their surroundings
- a capacity for precise self-replication and self assembly
- a capacity for change over time by gradual evolution
The living states in terms of five foundations correct answers - Cellular Foundations
- Chemical Foundations
- Physical Foundations
- Genetic Foundations
- Evolutionary Foundations
Plasma Membrane correct answers a thin, hydrophobic barrier that regulates the movement of
molecules in and out of the cell
Cytoplasm correct answers - the internal volume of the cell
- consists of cytsol and dissolved biomolecules
Cytsol correct answers the aqueous solution of the cytosol
Nucleic Acids correct answers genetic material contained in the nuclei or nucleus of a cell
Nucleic Acids in Bacteria correct answers genetic material is contained in the nucleoid which is
not separate from the cytosol
Nucleic Acids in Eukaryotes correct answers genetic material is contained in specialized
organelles called the nucleus
Two basic classes of living organisms correct answers Prokaryotes and Eukaryotes
Prokaryotes correct answers - "before nucleus"
- small, simple, single celled organisms
- their potential for rapid growth and division allow quick adaptation to changing environmental
conditions
, - a single compartment, the nucleoid, contains nucleic acids; other biomolecules are in a
complex, organized mix
Eukaryotes correct answers - true nucleus
- large complex cells
- make up multi-cellular organisms such as yeast, plants, fungi, and vertebrates
- organelles to support specialized functions
- differentiation of cells to unique and specialized cell types
Similarity in Prokaryotes and Eukaryotes correct answers use a common repertoire of building
blocks to create nucleic acids, proteins, polysaccharides, and lipids
The Four Major Classes of Macromolecules correct answers - Proteins
- Nucleic Acids
- Polysaccharides
- Lipids
Macromolecules: Proteins correct answers linear polymers of amino acids which serve a wide
range of biological functions (enzymes, receptors, transporters, etc.)
Macromolecules: Nucleic Acids correct answers linear polymers of nucleic acids that are
involved in all aspects storage and utilization of genetic information
Macromolecules: Polysaccharides correct answers polymers of sugars that serve in structural,
energy storage, and cellular recognition roles
Macromolecules: Lipids correct answers fats, and aggregates of fats, that serve in energy storage,
formation of membranes, and signalling
Biomolecules correct answers -often represent polymers of simple building blocks
- the structure and function of the final biomolecules are more complex than their precursor
molecules; the whole is greater than the sum of the parts
- within the cell, biomolecules undergo complex, organized interactions
Reductionist Approach correct answers an approach of studying molecules in isolation that
simplifies experiments, but possibly at the expense of biological significance
Two experimental approaches: correct answers - In Vitro and In Vivo
- experiments successful in vitro often fail in vivo because of the greater complexity of the
system
In Vitro correct answers - "in glass"
- studies the behaviour of molecules outside the context of the cell and organism
In Vivo correct answers - "in the living"
- studies occur within the context and complexity of the cell organism
