Biology Questions with complete
solution 2025/2026
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.
