Questions and simplified correct
Answers
active transport - correct answer-movement of molecules across a cell membrane from a region of lower
concentration to a region of higher concentration—against the concentration gradient. Active transport
requires cellular energy to achieve this movement.
passive transport - correct answer-Requires NO energy, movement of molecules from high to low
concentration, moves with the concentration gradient
covalent bond - correct answer-A chemical bond that involves sharing a pair of electrons between atoms
in a molecule
ionic bond - correct answer-Linkage formed from the electrostatic attraction between oppositely charged
ions in a chemical compound. Such a bond forms when the valence (outermost) electrons of one atom
are transferred permanently to another atom.
allosteric bond - correct answer-The regulation of an enzyme by binding an effector molecule at a site
other than the enzyme's active site.
Substrate - correct answer-reactant of an enzyme-catalyzed reaction
substrate-enzyme complex - correct answer-The substrate connects to the enzyme to perform chemical
reactions. It connects to the enzyme at the active site.
substrate enzyme inhibition - correct answer-the substrate or product of an enzyme reaction inhibit the
enzyme's activity.
Carbohydrates - correct answer-Are sugar molecules- our body breaks down carbohydrates into glucose.
Glucose, or blood sugar, is the main source of energy for your body's cells, tissues, and organs.
Proteins - correct answer-Chains of amino acids
Lipids - correct answer-Energy-rich organic compounds, such as fats, oils, and waxes, that are made of
carbon, hydrogen, and oxygen.
nucleic acids - correct answer-Nucleic acids are naturally occurring chemical compounds that serve as
the primary information-carrying molecules in cells. The two main classes of nucleic acids are
deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Lysosomes - correct answer-An organelle containing digestive enzymes
Vacuole - correct answer-Cell organelle that stores materials such as water, salts, proteins, and
carbohydrates
