CCBC BIOLOGY 109 EXAM 1
QUESTIONS WITH VERIFIED
ANSWERS
Steroids - ANSWER-Large Lipid molecules, share distinctive carbon-ring framework,
differ in functional groups attached to the ring
Phospholipids and Glycolipids - ANSWER-Both are synthesized by our cells
Both are diglycerides
Phospholipids - ANSWER-Phosphate group links diglyceride to nonlipid group
Micelles - ANSWER-Hydrophobic tails go away from water, heads go towards areas
of water
Proteins - ANSWER-large biomolecules, or macromolecules, consisting of one or
more long chains of amino acid residues.
Amino Acids - ANSWER-Building blocks of peptides that in turn combine to form
proteins
Enzymes - ANSWER-Catalysts in reactions
Specificity - ANSWER-lock and key
Efficiency - ANSWER-lowers activation energy for reaction
Control - ANSWER-controlled by genes, cofactors/coenzymes (minerals/vitamins)
Substrates - ANSWER-reactants for reaction
Substrates bind to surface of enzyme at active sites
Nucleic Acids - ANSWER-Organic molecules that contain carbon, hydrogen, oxygen,
and phosphorus
building blocks of nucleic acids
Deoxyribonucleic acid (DNA) - ANSWER-- Double Strain
- Genetic material, encodes instructions for protein synthesis.
- Double helix structure
- ATGC
-A=T
-G=C
Ribonucleic acid (RNA) - ANSWER-- Single Strain
- AGCU
, - Performs protein synthesis
Extracellular Fluid - ANSWER-Fluid surrounding cells
Interstitial fluid - ANSWER-Fluid in space between cells
ATP - ANSWER-Energy Molecule- Fueled by consumption of food/mitochondrion
ALL DNA IS STORED IN THE ________ - ANSWER-NUCLEUS
More fluid like the membrane is the _______ the transportation, the more rigid the
_________ it is - ANSWER-easier, harder
Cilia - ANSWER-hair-like projections of the plasma membrane that sweeps material
across cell surface
Flagella - ANSWER-Longer whip-like structure that helps cells move
Chromatin - ANSWER-DNA and proteins combined
Interphase - ANSWER-Cell increases in size, performs all necessary steps for
Mitosis
Freely Permeable - ANSWER-Anything is allowed to pass
Selectively - ANSWER-Only some are allowed to pass
Diffusion - ANSWER-Transferring from a high level of concentration to a low level of
concentration
Osmosis - ANSWER-Water transports from a low concentration to a high
concentration
Metabolic Pathway - ANSWER-Series of complex reactions where the product is the
reactant for another reaction
Decomposition - ANSWER-Reaction that breaks a molecule into smaller fragments
Hydrolysis- - ANSWER-Take a compound, combined with water, and it splits a large
compound.
Catabolism - ANSWER-Taking big and complex components and breaking them
down into their smaller components
Synthesis - ANSWER-Take two individual pieces and throughout the process to form
a compound
Dehydration synthesis - ANSWER-Formation of a complex molecule by removing a
water molecule
